cmake broken in svn rev. 971?

[Joczhen]

Hi,

I'm not able to build the complete bullet project with the latest revision 971 from svn.

It fails because he tries to link multiple object files with function main together to one shared object file.

Code: Select all

Linking C shared library libLibXML.so
CMakeFiles/LibXML.dir/runtest.o: In function `main':
runtest.c:(.text+0x3cd0): multiple definition of `main'
CMakeFiles/LibXML.dir/runsuite.o:runsuite.c:(.text+0x1b40): first defined here

make[1]: *** [Extras/LibXML/CMakeFiles/LibXML.dir/all] Error 2
make: *** [all] Error 2

Below you'll find a patch to create a static library instead.

I'm pretty new to this project, so I don't know whether I'm doing something wrong or if cmake isn't intended to work.

2. there is a typo in Extras/BulletMultiThreaded/SpuParallelSolver.cpp (see patch below)

After these two simple changes make finished the build process.

Thanks a lot for the fixes, cmake should be working and supported on all platforms.

btQuickprof should be lower-case, and there are some files in libxml project that should not be part of the library (they include 'main' methods and are probably for testing libxml).

Can you check if the latest trunk builds?
Thanks,
Erwin

[Joczhen]

works very good now! Thanks!
