Another follow up,
Since I am using the latest drivers and toolkit from NVidia (195 and 3.x,
respectively), I also attempted to compile pycuda against the emulation
driver. Still, I get the very same missing symbol error. I've been
meticulous with the LD_LIBRARY_PATH as well and can verify that the
dependencies are accessible.
libboost_python.so.1.42.0 => /usr/local/lib/libboost_python.so.1.42.0
(0x00007faeb6ec9000)
libboost_thread.so.1.42.0 => /usr/local/lib/libboost_thread.so.1.42.0
(0x00007faeb6cb4000)
libcudartemu.so.3 => /usr/local/cuda/lib64/libcudartemu.so.3
(0x00007faeb6a7d000)
Note that although the boost libraries are not installed under lib64, they
are in fact 64-bit:
ldd /usr/local/lib/libboost_python.so.1.42.0
linux-vdso.so.1 => (0x00007fff05dff000)
libutil.so.1 => /lib64/libutil.so.1 (0x00007f1da1cb7000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f1da1a9a000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f1da1896000)
librt.so.1 => /lib64/librt.so.1 (0x00007f1da168e000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f1da1383000)
libm.so.6 => /lib64/libm.so.6 (0x00007f1da1100000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f1da0ee6000)
libc.so.6 => /lib64/libc.so.6 (0x00007f1da0b77000)
/lib64/ld-linux-x86-64.so.2 (0x00000036fd400000)
Thanks again,
Paul
