Post 10: Getting CMUSphinx on your Slackware build.
(THIS IS INCOMPLETE)
I think this is a eparticularly difficult assignment. Since you are reading this, I assume you know what CMUSphinx is. If you do no, and you are curious check this out.
Among the first few challenges are to get the prerequisite softwares:
1] Get JDK. Consult this , if you do not already have the latest version of JDK.
2] get Apache Ant. I will elaborate on how to install Apache Ant when I find the time, but the installation shouldn't take much time. Remember, though, that upon successfully installing, you should, on running the command ant anywhere on your system (except when there is no build.xml file in your current directory), you should be able to to see the following output:
Buildfile: build.xml does not exist!
Build failed
3] Subversion will be a handy tool. Download subversion from here. Again, apologies for not elaborating. I am short on time and I will previde an elaborate description later.
4] Download your favourite IDE, say, Eclipse. You may want to consult this guide.

Post 9: Downloading all the files from a directory on the Internet.
Suppose someone tells you that you need to download all the files from a directory on the Internet, say, mirrors.usc.edu/pub/linux/distributions/slackware/slackware_source/l/vte/
, where .../vte/ contains all the files you need.
Personally, I found this quite tricky. In order to download all the files from this directory do:
wget -nH -r --cut-dirs=6 --no-parent mirrors.usc.edu/pub/linux/distributions/slackware/slackware_source/l/vte/
where ,
-nH --> --no-host-directories(the following have been directly lifted from the respective man page)
Disable generation of host-prefixed directories. By default, invoking Wget with -r http://fly.srk.fer.hr/ will create a structure of directories beginning with fly.srk.fer.hr/. This option disables such behavior.
-r --> files will be recursively retrieved. Say that /vte contained subdirectories a, b and c. Doing an -r would retrieve the files contained in all these directories as well. Without explicitly specifying the depth of this recursion, the default depth is 5. You can override the default depth by specifying the level explicitly as --level=x
--cut-dirs=6 --> ensured that you did not end up creating a hierarchy of directories from the path where you downloaded /vte. Without this prefix, you would have ended up with pub/linux/distributions/slackware/slackware_source/l/vte/. Instead, you want to prune away pub/linux/distributions/slackware/slackware_source/l/, which amount to 6 levels of hierarchy.
--no-parent OR -np --> (the following have been directly lifted from the respective man page)
Do not ever ascend to the parent directory when retrieving recursively. This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.

Post 8: Installing Eclipse on Slackware.
(*** Apologies if you tried this and it did not work! ***)
(*** Please refer the very last portion of the post, regarding exporting. ***)
Running Eclipse on Slackware 14 seemed extremely simple.
1] Download the version of Eclipse you want from this page.
2] Go to the directory where the download is.
For example,
cd /home/<username>/Downloads
3] tar -xvf eclipse-SDK-4.2-linux-gtk-x86_64.tar.gz
4] You will notice that a directory called eclipse has been created. Go inside the directory and type eclipse. If everything has gone the way it should, Eclipse should work.
5] Now, you probably want to move this out of your Downloads directory, say, to the /usr/local path. So do the following:
cp -r eclipse /usr/local
5] You do not want to manually go to /usr/local/eclipse every time you want to run Eclipse, so you create an alias. Open ~./bashrc. ie.
vim ~./bashrc
(If there is no such file already, vim would create one for you)
6] Create an alias for the executable, that is, /usr/local/eclipse/eclipse, as follows:
alias eclips=/usr/local/eclipse/eclipse
(*** Please be advised that there should NOT be spaces between 'eclipse', '=' and '/' ***)
(I chose the alias 'eclips', you could name it anything you want. I am not sure what the complications are when you name it 'eclipse' and you go into the directory that contains a similar file - a name collision, basically . I guess it should be alright, since, in order to run /usr/local/eclipse/eclipse, you would have to type ./usr/local/eclipse/eclipse. Note the '.' at the start of the command)
To make this change effective, type the following command:
source ~/.bashrc
You should be able to run Eclipse by typing eclips anywhere.

PangoFc will not work correctly.:
1] Download the latest version of pango from here. Note that this particular download is for a 64 bit version of slackware.
(Re)Install Pango for slackware from
2] Do a upgradepkg --install-new pango-1.30.1-x86_64-1.txz. If this tells you that Pango is already installed, then you need to do the following:
upgradepkg --reinstall --install-new pango-1.30.1-x86_64-1.txz
NOTE : If you are facing the same problem on some other Linux-OS, perform the corresponding reinstallation procedure on that.

Solution to (acroread:1525): Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.:
1] Download the latest version of pango from here. Note that this particular download is for a 64 bit version of slackware.
(Re)Install Pango for slackware from
2] Do a upgradepkg --install-new pango-1.30.1-x86_64-1.txz. If this tells you that Pango is already installed, then you need to do the following:
upgradepkg --reinstall --install-new pango-1.30.1-x86_64-1.txz
NOTE : If you are facing the same problem on some other Linux-OS, perform the corresponding reinstallation procedure on that.
Post 6: Installing 32-bit softwares on Slackware64
Please follow the instructions on this link on multilibs. I have extracted the essence of what the page instructs here. Basically, what you will be doing is enabled execution of 32-bit softwares like XAMP, on your 64-bit Slackware system.
1] Make sure you have lftp service on your SlackWare install. Otherwise , download and install it from here. (Be advised that I have not had the need to install lftp manually, but doing so shouldn't be a big problem)
cd /home/<username>/Downloads
installpkg --install-new lftp-4.3.8-i486-1.txz
You should be done.
2] You are in /home/<username>/Downloads
Create a temporary folder called, say , LFTP and cd into it.
cd LFTP
3] Run the following commands and read read the brief notes .
lftp -c 'open http://slackware.com/~alien/multilib/ ; mirror 14.0'
(where 14.0 is the version of your Slackware build. The latest version at the time of writing is 14.0.)
After you are done downloading all the files from the mirror, you will notice that a new
directory is created. In this case, you will have a directory called 14.0. cd into it.
cd 14.0
4] Enter the following command in the terminal:
upgradepkg --reinstall --install-new *.t?z
You would have installed all the packages present in the directory upon it's execution.
Additionally, you will find a new package create called compat32-tools.
5] cd to the directory slackware64-compat32
cd slackware64-compat32
and run
upgradepkg --install-new *-compat32/*.t?z
6] Finally, run
massconvert32.sh -u http://slackware.mirrors.tds.net/pub/slackware/slackware-13.1/slackware
7] Now, test if all this really works... I tried to run XAMPP, which is meant for 32-bit systems exclusively, and it works! Adobe Reader works too!
WELCOME TO THE BLOG
Hello, like you (maybe), I am a SlackWare beginner. With any Linux-based OS, the primary problem with getting used to it is that one may easily forget the way an arbitrary, yet previously successfully attempted, change needs to be implemented. For example, you may finally manage to install Google Chrome on your new Slackware build, but you may forget what you did to install it within a few days. Such things should be documented... So too is the purpose of this blog. While it is primarily meant to serve as a ready-reference for me in the future, I hope that you can also make use of the information I post on this blog.
If you find any discrepancies in any of my posts, I strongly urge that you point them out to me, so that I may rectify my mistake(s) and learn from them.
Good Day!
Rahul Rajaram.

Post 5: Install Google Chorme on Slackware
Follow the instructions on this link. If that does not help, you could refer to the following steps, which I have merely paraphrased.
If you are using a 32-bit install of Slackware:
1] Download Google-Chrome meant for Debian-32 bit from here.
2] Go to this. Look for the title Download SlackBuilds and download google-chrome.tar.gz.
3] Now, cd to the directory that contains google-chrome.tar.gz and untar it.
For example,
cd /home/<username>/Downloads
untar-ing:
tar -xvf google-chrome.tar.gz
4] Copy the google-chrome... .deb file into google-chrome
cp google-chrome-stable_current_amd64.deb google-chrome/
5] Go into this new directory and run the following command:
sh google-chrome.SlackBuild
For a 64-bit install of slackware, you need to make the following modifications:
1] cd /home/<username>/Downloads/google-chrome
2] Modify the contents of google-chrome.SlackBuild:
- Change the value of ARCH from i368 to x86_64
- Wherever you find google-chrome-beta_current, change it to google-chrome-stable_current. (You would need to change this in only two or three places)
3] Now, run sh google-chrome.SlackBuild, and you should be done.
IMPORTANT: By default, you will not be allowed to run Google Chrome as a super user. To make it so that even as a super user you can run Google Chrome do the following:
1] vim /usr/bin/google-chrome
2] Go to the last line of this file and hit space. Do not go to the next Line.
3] append the last line with --user-data-dir

Post 4: Install a package that ends with the .txz/.tgz
Whenever you see a file that ends with the .txz/.tgz extension, it means that you will be able to install the package that the file represents. For example, if you want to install Adobe Reader on your Slackware machine, you install the package using the following command:
installpkg --install-new adobe-reader-9.5.1-i486-1sl.txz
installpkg --install-new adobe-reader-9.5.1-i486-1sl.txz
Post 3: SSH basics
I wanted to doenload files from a remote machine. So, I found the need to use the scp command. Check the following link out. Remember, though, that when you need to scp a directory and not any single file, you will need to do a scp -r <hostname>@...
I will post more links here, when I find them and if I find them appropriate.

Post 2: Download and install LibreOffice
Even Slackware's full DVD install does not seem to come with LibreOffice, so I had to manually download the binaries from OpenOffice.org.
Step1: Download the appropriate tar file from http://www.libreoffice.org/download/?type=src&version=4.0.3. I assume that the first file should be alright.
Step2: Go to the directory where you downloaded the file and do the following. For example
cd /home/rahul/Downloads
unxz libreoffice-4.0.3.3.tar.xz
tar -xf libreoffice-4.0.3.3.tar
cd /libreoffice-4.0.3.3
Step3: Now, you are inside libreoffice-4.0.3.3. You need to do the following:
./configure
make
make install
Problems you might face:
PERL:
- You may be told that certain Perl modules aren't found. You need to follow the subsequent commands to solve the issue. (You may be prompted to install cpan):
$ su -
cpan
cpan> install Archive::Zip
cpan>quit
JAVA:
- Problem of the sort of 'JDK not found'
Follow this. If that didn't help, see if this tells you where you are going wrong.
krb5_sendauth (KERBEROS):
- 'could not find function 'krb5_sendauth' required for Kerberos 5'
Go here and download and install the appropriate package.
Gnome-VFS:
- Download your version of gnome-vfs here and install it using the following command (also present on the site):
./configure --without-junit
make install: throws an error when I try running it. Specifically, the error is as follows:
ERROR: Include file cliureversion.mk not found!
: ADD_INCLUDE_FILES = cliureversion.mk,clioootypesversion.mk at /home/rahul/Downloads/libreoffice-4.0.3.3/solenv/bin/modules/installer/worker.pm line 960.
Step1: Download the appropriate tar file from http://www.libreoffice.org/download/?type=src&version=4.0.3. I assume that the first file should be alright.
Step2: Go to the directory where you downloaded the file and do the following. For example
cd /home/rahul/Downloads
unxz libreoffice-4.0.3.3.tar.xz
tar -xf libreoffice-4.0.3.3.tar
cd /libreoffice-4.0.3.3
Step3: Now, you are inside libreoffice-4.0.3.3. You need to do the following:
./configure
make
make install

krb5_sendauth (KERBEROS):
- 'could not find function 'krb5_sendauth' required for Kerberos 5'
Go here and download and install the appropriate package.
Gnome-VFS:
- Download your version of gnome-vfs here and install it using the following command (also present on the site):
# upgradepkg --install-new gnome-vfs-2.24.4-x86_64-1sl.txz
Junit:
- Chances are that you will be informed about the unavailability of 'Junit' . It is safe to ignore junit. You do this by configuring without junit:./configure --without-junit
make install: throws an error when I try running it. Specifically, the error is as follows:
ERROR: Include file cliureversion.mk not found!
: ADD_INCLUDE_FILES = cliureversion.mk,clioootypesversion.mk at /home/rahul/Downloads/libreoffice-4.0.3.3/solenv/bin/modules/installer/worker.pm line 960.
Once I figure out what the fix is, I will update the post.

POST 1: Installing Java on Slackware.
Installing Java on Slackware turned out to be relatively simple. All that you have to do is follow guide in the following page and have the Slackware DVD with you. (If you do not have the DVD, all you need to do is download them from here, put all the files in the same directory and then go to the directory to perform the actions prescribed in the Official Slackware guide)
Official Slackware guide: http://docs.slackware.com/howtos:software:java
Note, however, that you need to make a slight modification to a couple of the commands. Specifically, you need to get the version number of the download correctly. For example, the file I downloaded had the prefix jdk-7u21-x86_64-1, where 7u21 is the latest version of JDK. Be sure to modify the "-xuyz-" part of the command. Also, if you be sure to download the right version of jdk.
