As a follow up,
My system is a fedora 11 with the latest kernel
(2.6.30.10-105.2.23.fc11.x86_64), nvidia drivers and boost library (1.42).
I've double checked that the library dependencies are accessible and
present. I've also listed the symbol table in libcudart.so and the symbol
('cuTexRefSetAddress') reported missing does indeed exists.
The following lists what the pycuda driver wrapper is linked against:
linux-vdso.so.1 => (0x00007fffb39ff000)
libboost_python.so.1.42.0 => /usr/local/lib/libboost_python.so.1.42.0
(0x00007f8bc42f6000)
libboost_thread.so.1.42.0 => /usr/local/lib/libboost_thread.so.1.42.0
(0x00007f8bc40e1000)
libcudart.so.3 => /usr/local/cuda/lib64/libcudart.so.3 (0x00007f8bc3e86000)
libpython2.6.so.1.0 => /usr/lib64/libpython2.6.so.1.0 (0x00007f8bc3ad9000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f8bc37ce000)
libm.so.6 => /lib64/libm.so.6 (0x00007f8bc354b000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f8bc3331000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f8bc3114000)
libc.so.6 => /lib64/libc.so.6 (0x00007f8bc2da6000)
libutil.so.1 => /lib64/libutil.so.1 (0x00007f8bc2ba3000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f8bc299e000)
librt.so.1 => /lib64/librt.so.1 (0x00007f8bc2796000)
/lib64/ld-linux-x86-64.so.2 (0x00000036fd400000)
Thanks,
