I am not familiar with installing mpich and am having problems with installation. I have found from searching online that mpich-1.2.6 produces libmpich.so.1.0 which I require run a certain program in parallel. I am unable to follow the installation documentation I have found online for this version because when i configure for ch_p4mpd I get an error when I run make. Therefore I just run ./configure and make but this does not produce my required libmpich.so.1.0. What do I need to specify prior to either configure or make in order to build this? I am building on a linux86-64 with pgi/10.2 compiler.
