[Linuxppc-users] Caffe compilation failed

[Jason Furmanek]

Generally, Nvidia code only supports the kernel/GCC/GLIBC levels of a 
particular distro.

See:

http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#system-requirements


Sometimes newer kernels work, but a lot of their Cuda code gives compile 
time errors like this on newer toolchains. Basic reasoning as far as I 
can tell is their code is closed so they have to do all of the work 
themselves, which means they pick certain levels to support in order to 
contain it.
