Kernel sources not found on Scientific Linux 6

[Taomach]

Hello!

I am having trouble installing NI-VISA on Scientific Linux 6. The installer can not find kernel source despite the fact the kernel-headers and kernel-devel packages are installed. How to point the NI-VISA installer to the kernel source location?

Hello,

It looks like there's some information about this listed in the installation instructions and installation FAQs of the readme file for NI-VISA here.  Have you looked through this before your attempted install?
