[Linux, 64-bit] Compiling Issue - Python? posixmodule.o?

[ProxyIchig0]

I've been trying to compile the engine from source and have encountered some odd problem. I'm running Linux Slackware 13.0, with an Intel Core 2 Quad.

*CMake runs properly as far as I can tell:

bash-3.1$ cmake ..

*But after running make, I get some warnings and then errors:

*What is the problem or what should be changed? I tried installing the latest version of most dependencies, but so far with little luck. Any Ideas?

Thank you.

[kripken]

The warnings can be ignored, but not sure about the link errors. Some Googling suggests to link with 'util' (that is, add -lutil to the link command). Can you test if that fixes it?

Yes, that seems to fix things.

I added -lutil to CMAKE_EXE_LINKER_FLAGS and CMAKE_MODULE_LINKER_FLAGS. I'm not sure if both were necessary.

Thank you for the fix. I even started up the client for a bit and it seemed to run fine. I just hope no one else trying intensityengine, gave up if they encountered this. But considering it's relatively new and has impressive potential, any gamer and modder I know of wouldn't give up so easily.

Thanks again!

[kripken]

Glad it worked.

Kind of an odd problem, I guess it is something to do with CMake not correctly detecting system libraries on Slackware. I added a mention of the issue to the COMPILE.txt file for other people.
