ERROR: Failed to load COLLADA conversion DLL

[jinzo]

Hello,

So I compiled 0 A.D from SVN on Gentoo Linux. Compiling went reasonably well, now I encounter an error when I start the game:

ERROR: dlopen error: ./libCollada_dbg.so: cannot open shared object file: No such file or directory
ERROR: Failed to load COLLADA conversion DLL
ERROR: Could not load mesh 'art/meshes/structural/settlement_1.dae'
ERROR: CObjectEntry::BuildModel(): Model art/meshes/structural/settlement_1.dae failed to load

That's after I try to start the Single Player mode.

Before that, I get some warnings/errors, I'm posting the whole log here:

P.S: That's the same error as here.

Do you need any further info ?

Greetings!

Uhoh, those previous errors are already showstoppers.

Since even the simplest of the VFS mount calls is failing (line 570, accessing pre-existing directories within the SVN tree), it looks like we're failing to determine the executable's directory.

Does it help if you launch the game from gdb, which sets argv[0] correctly? Can you please step through source/lib/sysdep/os/linux/linux.cpp's sys_get_executable_name and check what source/ps/GameSetup/Paths.cpp's Paths::Root is returning so we can find out the cause?

Unfortunately I can't help much with the libCollada problem (am developing on Windows). Do you see anything in the build log that indicates the .so wasn't actually built?

[jinzo]

Hello,

Thanks for your replay. Looks like there was something wrong at compile time. Today I recompiled the game with "make" ( instead of "make -j5" ) and now it works.

Keep up the good work! The game looks really promising.

What is "0ad"? (The game currently requires the pyrogenesis_dbg executable to be run from a non-PATH-based command so it can find it from (effectively) argv[0]; if you're running it strangely then that'll fail.)

[jinzo]

That was a wrapper script done by the gentoo ebuild. But as I allready figured out, there are some problems with that ebuild and parallel make. So that's solved, at least what's concerning 0 A.D development. Thanks for your help.
