After installing CUDA on a machine with Fedora Core 6 I saw the following problem when I tried to run SDK examples:
./bin/linux/release/template: error while loading shared libraries: /usr/local/cuda/lib/libtlshook.so: cannot restore segment prot after reloc: Permission denied
The solution was to change the SELINUX settings for the CUDA lib directory:
[root@park]# chcon -t texrel_shlib_t /usr/local/cuda/lib/*.so
I suspect that the same problem could occur on other machines with SELINUX.
