[mesa-users] Mesa revision 4153 installation error

[Neil Miller]

Hey,

It looks like you haven't defined the OMP_NUM_THREADS environment
variable.  For example, in my .bashrc file I have the line

export OMP_NUM_THREADS=8

It is suggested that this number correspond to the number of cores you have.

There is an error message that is supposed to show up if this variable
isn't defined and stop the installation script.  Perhaps we should
tell people they need to define this variable in the README or online
instructions.  We could also presumably set a default value if it
isn't defined.
