Hi Haris,

To expand on what David said, make sure you first update the package manager:

sudo apt-get update

Then look for the package:

apt-cache search SDL

This will list a ton of libraries--I think they're in alphabetical
order, though, so you can find what you need quickly. Look for a
version ending in "dev" or (in some cases) "devel" and either copy it
from the terminal window, or remember it, char for char. To install
it:

sudo apt-get install <exact package name>

BTW, you might also use aptitude instead of apt-get/apt-cache. As far
as I know, it does the same thing in a slightly-easier-to-use way.

HTH,
Brendan

I always use aptitude myself, but apt-get is what is recommended on
Ubuntu.  The gui package tools on Ubuntu use apt-get rather than
aptitude, and it is advisable to stick with one or the other.

Aptitude used to have some significant advantages over apt-get, mainly
better tracking of automatically-installed packages (so that
installing and then uninstalling a package didn't leave one's system
with all the no-longer-needed dependencies still there).  For that
reason, aptitude has been preferred over apt-get on Debian for several
years.  For the most part, I use Debian rather than Ubuntu.

For whatever reason, Ubuntu has stuck with apt-get, but has also fixed
the tracking issues so that AFAIK there is no longer much of an
advantage to using aptitude.

Aptitude also has an ncurses interactive menu mode, but I always just
use it straight from the command line just like apt-get.

Cheers,

David

Hi,

To start of again fresh, I followed both Bruce's and Brendan's advice and
uninstalled all that I had installed from source like SDL_image, etc. I
cloned the repository anew with my "pull-push" privilege and ran autoreconf
(which worked fine when ran twice). Then while executing the configure file,
it pointed out which all libraries were missing. I apt-cache searched each
of them and apt-get installed them too. Everything went well and finally I
ran 'make' within the "build" directory. Here came the problem! A lot of
stuff came written on the screen of whose end was:

{
campaign.o: In function `briefPlayer':
/home/haris/mywork/project/tuxmath/build/src/../../src/campaign.c:206:
undefined reference to `T4K_LoadScaledImage'
collect2: ld returned 1 exit status
make[2]: *** [tuxmath] Error 1
make[2]: Leaving directory `/home/haris/mywork/project/tuxmath/build/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/haris/mywork/project/tuxmath/build'
make: *** [all] Error 2
}

And when I ran sudo make install, the end of the long line of outputs was:

{
campaign.o: In function `briefPlayer':
/home/haris/mywork/project/tuxmath/build/src/../../src/campaign.c:206:
undefined reference to `T4K_LoadScaledImage'
collect2: ld returned 1 exit status
make[1]: *** [tuxmath] Error 1
make[1]: Leaving directory `/home/haris/mywork/project/tuxmath/build/src'
make: *** [install-recursive] Error 1
}

What maybe wrong here now? It had worked fine earlier (without music).

Thanks,
Haris.

Make sure libt4k_common is being linked (also, make sure that it
*should* be linked! In the branch named master, T4K_Functions ought
not to be used)--look at the command for the linking step, which
should have a bunch of arguments like -lSDL -lSDL_mixer -lpthread -lm
and so forth. Is -lt4k_common one of them?

FWIW, I have the exact same problem.

OK, that's a bug in our code.  "T4K_LoadScaledImage()" is a function
from the new t4kcommon library, which is used by tuxmath's
"commonification" branch.  There shouldn't be any use of t4kcommon
functions in the master branch (at least until we get around to making
"commonification" the new "master", which should take place very
soon).

I would suggest going to line 206 in campaign.c and changing
"T4K_LoadScaledImage" to "LoadScaledImage", assuming that is the
correct function name in loaders.h/c, and see if it works.  If so, it
is your first bug fix!

However, the "commonification" branch is really our current dev
branch, so I wouldn't suggest spending too much time on the current
master.

Cheers,

David

Re: [Tuxmath-devel] Configuring the source code.

[blucalvin <blu...@gm...>]

Bingo!

Now got everything right. I changed the 206th line as Bruce had suggested
and "make" along with "sudo make install" worked fine. And the music and
sounds are working fine too. So now its up and running.

So the code I have downloaded is the current master right? How can I get
hold of the "commonification" branch? And is that term technical or just a
reference name? I would like to start development as soon as possible.

Looking forward to getting along with the job,
Haris.

It is a remote branch of the tuxmath git repo - see:

http://book.git-scm.com/4_tracking_branches.html

If you haven't done so already, create a local git clone that supports
pushing (i.e. writing) as well as pulling, and do the same for our new
t4kcommon library:

git clone git+ssh://blu...@gi.../git/tux4kids/tuxmath.git
git clone git+ssh://blu...@gi.../git/tux4kids/t4kcommon.git

(tuxmath and tuxtype have shared a lot of similar code for some time,
and t4kcommon is our project to make this into a proper library).

First go to your t4kcommon repo and build and install the library just
as you did for tuxmath:

mkdir build
cd build
autoreconf -if ..
../configure
make
sudo make install

(you may need to add /usr/local/lib to your system's link path, which
on Debian and Ubuntu can be done by simply running "sudo ldconfig"
with no arguments.  This only needs to be done once).

Then go to your tuxmath git repo and check out the "commonification" branch:

git branch --track commonification origin/commonification
git checkout commonification

This will change the contents of your local working copy to match the
commonification branch.  Now you can build and install our latest
current version.

I would recommend that you keep reading the git book and familiarize
yourself with the "pull" and "push" operations, commits, and local
branches.  Your work flow could be something like this:

(cd to tuxmath git directory)
git checkout commonification
git pull
(work on some files with editor of choice, test your changes, etc.)
git commit -a
git push

Everyone in the project has privileges to push commits into the repo,
but try not to push anything that breaks stuff.  Start out with minor,
innocuous stuff.  Of course, feel free to do whatever you want on your
own machine.  Local branches are good for trying out more radical
ideas, and you can simply delete the branch whenever you like.  It is
considered good git practice to do development in local branches, and
then use "merge" or "rebase" to move your work into the tree.

You really need to get a feel for git before you can do much with the project.

Best,

David
