Hey - it seems like the math library is not being linked in. Apparently it's
required by that version of python, and cmake can't figure that out.
A workaround: try adding the library to the cmake file in src/CMakeLists.txt.
You'll want to change:
target_link_libraries(qpid-dispatch ${Proton_LIBRARIES} ${pthread_lib}
${rt_lib} ${dl_lib} ${PYTHON_LIBRARIES})
To:
target_link_libraries(qpid-dispatch ${Proton_LIBRARIES} ${pthread_lib}
${rt_lib} ${dl_lib} ${PYTHON_LIBRARIES} m)
Totally untested - I don't have access to a centos5 box atm. I'm assuming
libm.so is available on your system.
Then remove the CMakeCache.txt file in your build directory, and re-run cmake.
Don't forget to change the python settings before building.
I wouldn't try python 3.3 at this point, IMHO.
