build issue on macosx

[serena-ivaldi]

Hello, I'm trying to install metapod on macosx. I've succeeded in installing all dependencies with homebrew, now I'm compiling and the building fails but I have no idea why. Cmake gives no errors, here's the output of the make (the part giving errors):

Hello Serena

you build system is trying to link this following executable (a test_

Linking CXX executable test_backward_traversal_prev_simple_humanoid
...
Undefined symbols for architecture x86_64:
"_main", referenced from:

but fails because the object file has no "main" function.
If you look at the source file you'll see that the main function is indeed not defined. This is because we expect the boost test framework to provide it.

Maybe playing with boost options in the CMakeLists.txt might help. You could also simply skip the tests.

Hope it helps

To be honest we never tried here on clang.
I ll try tomorrow on ubuntu 12.04 lts with clang.
Thx for the feedback.

Hi Serena,
Thanks for your feedback,
I tried with clang on Ubuntu 10.04 finally, and it looks like there is
some work to do to make it working.
Maybe I should try with a more recent distribution.
Unfortunately I am bit of a shortage time right now for the rest of the
month.
August will be more favorable for me on this.

Best, Olivier.
