This is probably a case of the blind leading the blind but....
you've got a few errors e.g
gcc Not found in current path*** ERROR: Some required tools are missing or were not found. ***[/CODE]
I got a little further (since I have gcc and the kernel source installed) but then got this error
[code] *********************************** ERROR ************************************* ERROR: 3.1 kernels are not supported! ** Running a 2.4.x or 2.6.x kernel is required to continue this installation. ************************************ ERROR ************************************
So I'm guessing it won't work (properly?) with 12.1. I am just going through installing 11.4 (which uses kernel version 2.6.x).
NB:
These errors were for only the GPIB and the VISA but I'm not going to faff around with seeing which "parts" might work although Labview did run without quitting (version 8.5)
