When I installed the pgf yesterday, I was able to run my model by using ‘make’. I did something (to try to solve other problems), and it’s not working anymore. The message is saying
make: pgf90: Command not found
This morning I changed $PATH, and it might have caused the problem. However, I have no idea.
What should I do to make my machine to recognize pgf90/pgf77 that I installed?
