[Pw_forum] installing OpenMPI and Quantum Espresso on a Mac OS X system

[Michael Hayden]

Alain,

Again, thanks for your efforts and time.

I have successfully installed and tested OpenMPI.  I also configured  
Quant Espresso and received the "Parallel environment detected  
successfully, configured  for compilation of parallel executables"  
response at the end of the config process.

I then compiled it,but the end of a very long output read:

ld: in /usr/local/lib, can't map file, errno=22
collect2: ld returned 1 exit status
make[1]: *** [pw.x] Error 1
make: *** [pw] Error 2

This doesn't look good and I can't find any list of these errors in  
the user guide.  I tried example01 and received (of course) this output:
ERROR: /usr/local/espresso-4.0.5/bin/pw.x not existent or not executable
Aborting

Any ideas?

cheers,
Mike
