I had downloaded and installed OpenMPI on my Mac OS-X 10.6 machine a few months ago. I ran the configure and install commands from the FAQ with no problems. I recently upgraded to Max OS-X 10.7 (Lion) and now when I run mpicc it cannot find the standard C library headers (stdio.h, std lib.h…) I had noticed that I had to modify my path to point to the Xcode gcc executable, /Developer/usr/bin/gcc, (I believe 10.6 included gcc in /usr/bin, but 10.7 does not appear to include it there now). So I figured that I could just reinstall OpenMPI and it would be able to locate the new libraries. However, during the "configure" operation I received the messages below. I normally use the Apple Xcode IDE for my initial code development and then compile using mpicc from a terminal window. gcc also fails to find the standard libraries from the command line. Is there an environment variable that I should set that tells gcc where the libraries are located?
Thank you!
