You don't have standard C++ math library on your system ??? Very strange...

Comment 2 Guillaume Paumier 2011-05-02 10:28:21 UTC

I don't know. This happened after a distribution upgrade, maybe there was some wonkiness there?

Do you know what ubuntu package this library belongs to, so I can check?

Comment 4 Guillaume Paumier 2011-05-02 10:59:24 UTC

Libm was installed:
http://packages.ubuntu.com/search?suite=natty&&arch=amd64&mode=filename&searchon=contents&keywords=libm.so

It was a cmake cache issue. After clearing the build directory and redoing a cmake, everything works fine.
