Likely you have system boost headers installed (like in /usr/include). These probably got picked up for the build and then ended up mismatching those of a separately installed newer boost. Just deinstall the system-wide boost dev stuff using rpm. If that's not the case, then check with ldd /usr/local/lib64/python2.5/site-packages/pycuda-0.90.2-py2.5-linux- x86_64.egg/pycuda/_driver.so that the right boost library is getting picked up and report back. Also, why use an old version (0.90.2) of PyCuda? 0.91.1 is out and fixes numerous bugs. (and has more features) Andreas
