RE: [Condor-users] Problem running examples about PVM

I may be able to help, but it's been awhile since I worked with condor-pvm, so please bear with me.

Yeah, if you can't find pvm3.h you'll have all sorts of trouble.

Changing that first '-I' enabled you to pick up the system's default pvm3.h, which is why it *almost* worked.

Condor ships a _slightly_ altered version (4 lines of code) of PVM.  See

http://www.cs.wisc.edu/condor/pvm/ and 

Those pages are quite old, but I believe they are still valid.  I believe that condor makes its own version of pvm available (the entire pvm distribution, not just the few condor-pvm binaries).  The pvm 3.4.1 distribution is available from the pages above; I don't know if a more recent version is available.

If you can alter the installed version of pvm in /usr/share/pvm3, just change the four lines of code described above and it should work for you.

Hope that helps,
