Great to see you still working on this. :)

Sorry for the redundant issue. Just wanted to give you a virtual high five. When I saw that Berlios was gone, I assumed this was too.

Looks like I'm missing a boost dependency. I can't actually see libboost 1.53 in Mint 17. Perhaps this kind of thing should be statically compiled i.e. bundled with/inside Antargis?

$ antargis
antargis: error while loading shared libraries: libboost_signals.so.1.53.0: cannot open shared object file: No such file or directory

Loaded Antargis, tried the tutorial. I see 2 leaders with their men sat around campfires. There is no instruction on what to do.

I get the following issues when trying to compile antargis against libpng 1.6 (which is the default version here on Mageia):

My guess would be that it would work if I were to compile using libpng 1.2, but even though it's available in my repositories, since SDL_image requires libpng 1.6, the build system seems to try to use the latter no matter what.

I could have a go at patching the buildsystem so that it uses libpng12, but maybe it would be better to port antargis to libpng16 which is pretty standard nowadays?

I'm not a developer myself, but for some context about what would need to change to port to newer versions of libpng, you can see for example what Stratagus had to change: http://bazaar.launchpad.net/~stratagus/stratagus/trunk/revision/7993#src/video/png.cpp

I copiled boost from scratch using the LFS way:

http://www.linuxfromscratch.org/blfs/view/7.6/general/boost.html

These were the 3 commandline things I used:

./bootstrap.sh --prefix=/usr &&
./b2 stage threading=multi link=shared
./b2 install threading=multi link=shared

Am I missing something? Could perhaps the error message
show some additional information related to boost?

I can recompile boost from source, no problem, but I am
not sure what I am missing altogether.
