[solved] NVIDIA Linux 3.11 compatibility (error: ‘num_physpages’ undeclared (first use i

/usr/src/nvidia-325.15/os-interface.c: In function ‘os_get_system_memory_size’:
/usr/src/nvidia-325.15/os-interface.c:244:21: error: ‘num_physpages’ undeclared (first use in this function)
/usr/src/nvidia-325.15/os-interface.c:244:21: note: each undeclared identifier is reported only once for each function it appears in
/usr/src/nvidia-325.15/os-interface.c:245:1: warning: control reaches end of non-void function [-Wreturn-type]

Here’s a simple fix for Linux 3.11, edit nv-linux.h and replace num_physpages with get_num_physpages.

Or apply this patch:

Hopefully NVIDIA will release new drivers with this fix shortly.
