Beyond Beyond Linux from Scratch (lfs - part3)

Filed under
Linux
HowTos
-s

In continuing with my Linux From Scratch series with Part 3, I present my adventures in setting up a more productive desktop system. Up until this point I have concentrated on just getting the basic underlying system in place and later installing X and a window manager. Today we strike out on our own some as we venture out of the docbook to go beyond Beyond Linux from Scratch.

Picking up where I left off last time, without kde's ksnapshot I was going to need some way to take screenshots. I remembered Imagemagick contains the "import" tool, but I also remembered scrot. Scrot is a small, easy-to-compile utility that would meet my needs. So, that was the route I took. Download giblib and scrot.

Then it's as simple as:

tar -zxvf giblib-1.2.4.tar.gz
cd giblib-1.2.4
./configure --prefix=/usr && make
su to root
make install

And do the same with scrot:

tar -zxvf scrot-0.8.tar.gz
cd scrot-0.8
./configure --prefix=/usr && make
su to root
make install

Then at the cli, one can take screenshots using a command something like this:
scrot -d 6 desktop.jpg

In this example the option "-d" is delay in seconds. My command delays taking the screenshot for 6 seconds, giving one time to open menus or whatever.

My friend wrote me on the day, actually right about the same time, I published my LFS: Part 2 and sent screenshots of a window manager he installed probably more as a joke than anything. To his surprise I wrote back and said "how cuuute!" I had fluxbox installed already, but my next course of action was to install Equinox Desktop Environment. I googled for the site and downloaded the required library and ede packages. I followed the Installation How-to and they installed in about 5 minutes with no issue. And I can really say that I'm enjoying it. To make icons, one right clicks the desktop, chooses "New desktop item" and fills in the blanks. Ede comes with a few icons in it's package, so that's handy. To set a wallpaper, right click the desktop and choose "Background Settings," and browse to the desired wallpaper. Of course it has all these menu entries for which I don't have applications. Big Grin Actually a few have the corresponding apps and I installed a few. But just when I was thinking "if it just had some other desktops..." I find it does. In the panel there's an icon of an indistinguishable image that allows one to choose another desktop. I find that a little inconvenient as one has to click twice to reach the other desktop, but at least it's there. Included are settings for the fonts, colors and windecs. There are
other themes on the website.

So, for a nice little light desktop that takes about 5 minutes to
install:

Download: the efltk library and the Equinox Desktop Environment package.

tar -jxvf efltk-2.0.5.tar.bz2
cd efltk-2.0.5
./configure --prefix=/usr --disable-mysql --disable-unixODBC --enable-xft && make
su to root
make install

tar -jxvf ede-1.0.4.tar.bz2
cd ede-1.0.4
./configure --prefix=/usr && make
su to root
make install

Then either type:
/usr/X11R6/bin/xinit /usr/bin/startede
or put startede in your ~/.xinitrc file to start it.



        

        

        

        



In case you noticed in my screenshots the output of:


configuration error - unknown item 'OBSCURE_CHECKS_ENAB' (notify administrator)
configuration error - unknown item 'CRACKLIB_DICTPATH' (notify administrator)
configuration error - unknown item 'PASS_CHANGE_TRIES' (notify administrator)
configuration error - unknown item 'PASS_ALWAYS_WARN' (notify administrator)

That's one little bug to which I hadn't paid too much attention at the time of my last write up, but it's easily fixed by editing out those lines in the /etc/login.defs file, as those functions are now handled by PAM. They're harmless and I'd been too lazy to fix it before the screenshots and now I'm too laz...er... busy to redo the screenshots. Big Grin

Next order of business was setting up a word processor or office application. My sources directory had become quite large and at this point I found I was going to have to delete what was in it. Freeing up over 3 GB, I preceded with the download of latest version of OpenOffice.org at the time - beta 2 of 2.0. But what a mess I found. The binary package was all rpms at the time and source package was about 100 different directories with no central configure script or makefile. I wasn't about to spend all day cd into each of those and doing the dance, so I downloaded the 30-day trial of TextMaker. I really like this program, too bad it costs 50 bucks. And of course I have vim and nano installed, so hopefully by the time the textmaker trial is up, OpenOffice.org will have a decent package for us who don't have rpm installed. The installation of TextMaker is simply a matter of untaring/uncompressing the downloaded tar.gz into our directory of choice and the start binary is called tml. So unless you put that directory in your path, you will need the full command to start it.

For example in my case that would be:

/usr/local/textmakertrial/tml.

...Or actually I made a desktop icon to that for me. FYI, the BLFS handbook does contain full instructions for installing OpenOffice-1.1.4.

I soon grew tired of the little xterm and decided it was time to install Eterm. It was merely a matter of installing libast and then Eterm. No problems there and now I could use my "myeterm" script to which I've grown quite spoiled. Eterm is my favorite terminal emulator because you can customize it so easily. If you wish to use Eterm:

download: the libast library and

tar -zxvf libast-0.6.1.tar.gz
cd libast-0.6.1
./configure --prefix=/usr && make
su to root
make install

download: Eterm and

tar -zxvf Eterm-0.9.3.tar.gz
cd Eterm-0.9.3
./configure --prefix=/usr && make
su to roo
make install

The command I use to start mine so that it'll look like the terminal is running on the background (transparent with no windec or scrollbars etc.) is this:
Eterm --trans -g 75x25 -f white -F '-*-lucidatypewriter-medium-r-normal-sans-16-*-*-*-*-*-*-*' -O --tint=#ffffff --shade 0 --borderless --scrollbar-popup --scrollbar-floating --scrollbar no --double-buffer -a "toggles buttonbar false"

If you are like me, there is nothing more annoying than booting a system to do some work and notice that your time is off by 15 minutes or even 6 hours. There should be a law against an OS changing anything in the bios!!! This is another petpeeve of mine. To quietly handle this problem, I enlist the services of ntpdate. The instructions for installing NTP-4.2.0 are included in the BLFS docbook and work quite well. Follow those, and then instead of running the ntpd all the time, we can just use the included utility ntpdate. You can run ntpdate as a stand alone command any time you wish in any terminal, set it up to run periodically as a cron job, or as I do as a boot time service. After your ntp package install, forego the configuration instructions unless
you're needing to supply time service to your network. Instead:

nano /etc/rc.d/init.d/ntpdate
and simply type and save as root:

/usr/sbin/ntpdate -b time.nist.gov

Then as root issue the following commands to make it executable and run at boot:

chmod ug+xr /etc/rc.d/init.d/ntpdate
ln -s /etc/rc.d/init.d/ntpdate /etc/rc.d/rc3.d/S22ntpdate

You may even wish to adjust your bios time, and in which case you can add on the next line in your /etc/rc.d/init.d/ntpdate file:

/sbin/hwclock --systohc

The -b switch tells ntpdate to use 'settimeofday' instead of the 'adjtime', which I'm convinced is a curse from satan himself (no hate mail please). And the --systohc for hwclock tells it to set the bios time to our new adjusted system time.

For image manipulation, Gimp is outlined in the BLFS docbook, but if you follow it word for word, it won't be able to decode jpegs. So, modify their suggestions to:

./configure --prefix=/usr --sysconfdir=/etc --disable-print && make

And as a bonus, the menu entry in Ede now works. Big Grin

Some other applications from the BLFS docbook one might need are: unzip, which, and openssh. The instructions work well for these.

For a backup and the availability of xffm, I decided to include xfce4 as well. For the sake of brievity I don't think I'll outline each and every command used, as this is quite a collection of modules. However, download the xfce4 package. With the xfce4 package uncompressed you will find many directories containing the required library and base install as well as the different modules that you might like. Just cd into each one of interest and do the configure, make, make install routine. A graphical installer is available as well, although it installs an older version and the site is in German.

    

I use bash for my file manager, but it's always nice to have a graphical version available. A real nice and extremely useful one is emelfm. You can download it here. Installation is easy peasy, just

tar -zxvf emelfm-0.9.2.tar.gz
cd emelfm-0.9.2
make
su to root
make install

Note however, the executable will be located in /usr/local/bin.

So at this point we have our basic system with X and nvidia graphic drivers, three window managers from which to choose, xffm and emelfm for file management, mozilla and opera for browsing, news and email, feh, iv, and gimp for image viewing and manipulation, and TextMaker, vim, and nano for publishing and editing. Next is multimedia. <deep breath>

    

You may not know this about me, but I have to have xawtv. I've tried a lot of tv applications over the years, but none stack up to the stability and resource overhead of xawtv. So the next order of business was installing xawtv. This isn't the daunting task it once was before the kernel included bttv drivers. Now it's just simply a matter of enabling support in the kernel and installing xawtv. Xawtv is a fairly straight forward compile. Download: xawtv and tv-fonts.

tar -jxvf tv-fonts-1.1.tar.bz2
cd tv-fonts-1.1
./configure --prefix=/usr && make
su to root
make install

then:
tar -zxvf xawtv-3.94.tar.gz
cd xawtv-3.94
./configure --with-x --enable-gl --enable-quicktime -with-xvideo
--with-alsa --prefix=/usr && make

su to root and make install.

You'll need a configuration file, ~/.xawtv, and if you don't have one, here's an exerpt of mine for an example:

[global]
freqtab = us-cable

[defaults]
input = Television
norm = NTSC

[WKRN (2)]
channel = 2

[VMP (3)]
channel = 3

[WSMV (4)]
channel = 4

[WTVF (5)]
channel = 5

That was the easy one. Next I require mplayer, and I require mplayer to play anything it encounters. In the old days that meant downloading all the libraries and codecs from many many sources and reading a long doc to get all the flags to use during compile time. This became obsolete with distros like pclos, gentoo, and some others. All this to say, I'm a little rusty in this area. But thankfully the BLFS has the instructions in their docbook and a lot of the codecs are bunded together in one (or two) package(s). And of course, it went without a hitch. Using the information in the instruction I can now watch any movie file I run into.

    

Also included in the multimedia section of the docbook are xmms and cdrecording applications and tools. At the risk of repeating myself, the instructions work wonderfully in these areas as well and I recommend just following the instructions.

As of now, I have a fairly complete system all compiled from scratch and taking up about 1.3 gig of space. It boots in less than 30 seconds and performs very well. It's fast and stable. More than that is the satisfaction and sense of accomplishment that can come from completion or near completion of a daunting task. I found the whole experience quite fullfilling, educational and fun. I can't encourage you enough to visit the Linux from Scratch website and download your instruction book today.

Excellent series

Thanks for the LFS/BLFS/BBLFS series. They were very informative and makes me want to try it again. I did get a basic LFS up and running two years ago, but never went beyond mainly because the computer I was playing with is a P2 300 Sad Time to convince the wife that we really could use new computers Wink

re: Excellent series

Why thank you kind sir for your nice words. It was really quite a bit of work, but it was a labor of love - not done for the sake of an article (or 3). Big Grin

I know what you mean about the slower computers, I put gentoo on a p150 about 18 months ago and well, it don't get updated too often. Tongue

----
You talk the talk, but do you waddle the waddle?

re: comparison

Well, I'd say that gentoo is much easier in that it does all the grunt work for you. If I want an application/package in gentoo I type emerge <application> and it handles all the downloading and installing of dependencies as well as the compile and install. And their repository is so huge, I've rarely searched for something and it not be in gentoo's portage. Although some packages I prefer to do on my own, KDE being one of them, I can still get the dependencies installed through portage. For the source-based distro fan, it's like having your cake and eating it too. Fortunately the lfs/blfs docbooks lists dependencies and provides links, and that helps big time.

As far as kde not being installed on my LFS, I was being lazy or in too bigga hurry I guess. KDE itself is a fairly easy compile usually, but it does have a lot of dependencies and can take quite a bit of time. Yes, mozilla/firefox and opera were shortcuts to getting on the internet. The BLFS docbook contains instructions for kde and gnome.

Part 4 Perhaps? :)

Hi!

First off, great review regarding LFS!

I know it's been quite some time since your last review/reply to comments here. I've wondered how goes the LFS install?

Have you continued to tweak it, expand on the package? I've wondered if you kept it around, played with it, and, or, made it a part of your everyday computing experience Smile

I'll try not to date myself heavily here, I started way-way back with only a CLI learning basic/basica and dabbled in assembly. Through that time I went from dos/unix/posix/windows/linux (variations ie: DosLinux) and I always found myself coming back to Linux in one flavour or another.

Recently, the last year or so I've found myself totally going over to Linux. I missed the CLI environment and feel of yesteryear..lol With that I've been put off in a sense with many of the distributions and such that just seem to weigh down a really top-notch OS such as Linux. I stumbled across LFS somehow, who knows, and now my son and I (he's 14, yes I'm old) have a bit of a competitive project going on. We're both currently working on building the base LFS system then we're going to migrate to BLFS as well and see who's system is the best in functionality and asthetics, but not only that, we'll both be taking a step neither of us ever considered and it's kind've added another new excitement to beyond computing in general Smile

Your review was just what I was looking for and should've read it beforehand. It's helped a lot seeing someone successfully complete the process and give it a very decent pat on the back.

Thanks for taking the time to review it, and thanks for reading this rather lengthy comment Smile

Take Care!

re: Part 4 Perhaps? :)

Um, no I haven't kept it up. I played with it for a few months adding features and stuff, but I didn't implement one of the package management ideas and soon just quit messing with it. If I hadn't already been settled into Gentoo I might have made it my permanent system. It's a very cool project for sure. I surely enjoyed setting it up.

Thanks for your visit and comments. I might look around and see if I still have it around here somewhere and if it can be saved.

LFS or Arch Linux

Hi, Im reading this exellent review of LFS, because I have just downloaded liveCD of LFS. Im new to Linux, about four months, I have passed through few distros: Fedora, Ubuntu, and Slackware, ending up with Mint and Arch Linux. I wonder if you could compare LFS with Arch, witch I enjoy very much for its simplicity, speed, and the pacman command. But, Im thinking to give LFS a try, although some say that LFS is not good as distro for daily use, but just as learning experience to know Linux better.
Blessing.

re: LFS or Arch Linux

Well, I really couldn't compare LFS with anything else - not even Gentoo. Although Gentoo would probably be the closest. Arch is a binary distro with a great commandline package manager. LFS didn't have a package manager last I messed with it. There were methods of managing packages, but the user had to sorta build it from scratch. Big Grin

There's no reason why LFS couldn't be fine for an everyday desktop if that's what you wanted to do. If so, perhaps you might want to look into some of those described package management solutions.

Go ahead and go for it. I don't know how you have your disk partitioned, but I suggest slicing it up into several partitions so that you can play with one distro while keeping one or two intact for daily use.

LFS or Arch Linux

Hi,
thanks a lot for this fast reply. Yes. I will take your advice about partitioning. I wonder why there are so few good reviews of LFS. The more your afford is appreciated. Take care.

The nice thing about LFS

The nice thing about LFS is that you can always install any package manager including pacman, make packages and even start your own distribution.

OSS and Openwashing Leftovers

  • Why retail marketers must get CX right the first time and how open source plays a key role

    One of the great things about technology is that it has raised all of our expectations. Once upon a time, people worried that controlling their television with a remote would make them lazy. Now, we don't even have to find the remote. We just talk to the TV — literally. We access hundreds of goods and services easily, without leaving the comfort of our chairs: we download games, order the supermarket shop, watch films and read books online. It really is a brave new world. But with new worlds come new challenges, and the challenge of the new, tech-driven, marketplace is to make your business stand out in a global crowd. Of all the businesses in all the world, why should your customers choose (and stick with) you? Lots of people will tell you that the key to gaining market share lies in improving the customer experience. And they'll be right. A combination of the need to impress and increased customer expectations have combined to make CX fundamental to gaining and retaining custom.

  • The Future of Great Customer Experience Relies on Open Source

    A majority of U.S. consumers feel that brands don't meet their expectations. The bar for customer experience has been set high -- and its on marketers to reach it. [...] In the early 2000s, enterprise IT was dominated by proprietary software companies. Now, with the rise of public cloud computing, more and more developers are adopting open source tools within their organizations due to lower overall costs and access to the latest innovations. The adoption is spreading from IT into other sectors of the business as well, notably marketing. In total, marketing and experience cloud vendors invested over $8 billion to acquire open source companies in 2018, according to PitchBook.

ReactOS 0.4.12 features a lot of work on its open-source kernel including some driver compatibility enhancements, rewritten write-protecting system images, Blue Screen of Death fixes, and a lot of other low-level work.

  • Tencent Offers Open-Source System for IoT Innovation

    Chinese internet giants are quickly cottoning onto the benefits of offering open-source technologies to global developers. Tencent is the latest to throw its hat into the ring. The company announced Wednesday that it is allowing developers to use an open-source operating system to create an internet-of-things (IoT) projects that will allow Tencent to improve the performance of its IoT solutions and strengthen its foothold in the sector. Called “TencentOS tiny,” the operating system is lighter, requires fewer resources, and uses less energy compared with other major systems, according to a Tencent release. The company also said it hopes TencentOS tiny will encourage developers to create IoT projects for smart cities, intelligent connected vehicles, and digital wearables — sectors that Tencent is aggressively targeting.

  • How spicy should a jalapeno be?

    Everyone has opinions and preferences, especially when it comes to food. To establish a criterion when answering "How spicy should a jalapeño be?." the Scoville Heat Scale was developed as a standard to measure spiciness. This scale allows people to communicate and share information about how spicy we like our peppers. Similarly, open source technology standards, such as USB, I2C, MQTT, and others, were developed to enable global compatibility. Furthermore, open source hardware platforms have enabled communities to “speak the same language” without reinventing the wheel. For example, Raspberry Pi makes it easy for people to use their hardware as a baseline and then add onto it. This has created a revolution in many industries by enabling individuals, startups, and large corporations to apply hardware and software to complex problems without having to design them from the ground up.

Linux 5.4 Adds Support For The FlySky FS-iA6B - A Receiver Popular With DIY Drones

The input driver updates for the Linux 5.4 kernel include the addition of an interesting, budget-friendly RC receiver that can be used for home-built drones and other use-cases while now the driver allows the receiver when paired with a supported RC controller to serve as a traditional Linux joystick input. The input updates were sent in earlier this week and among the changes are allowing drivers to support more precise timestamps for better velocity tracking, improvements to the BU21013 touchpad driver, and other changes as outlined in the pull request.
