Hi, Interestingly, the errors are gone after I removed "-g" from the app compile options.
I tested again on the fresh Ubuntu 11.10 install: both 1.4.3 and 1.5.4 compile fine, but with the same error. Also I tried hard to find any 32-bit object or library and failed. They all are 64-bit. - D. 2011/9/24 Jeff Squyres <jsquy...@cisco.com>: > Check the output from when you ran Open MPI's configure and "make all" -- did > it decide to build the F77 interface? > > Also check that gcc and gfortran output .o files of the same bitness / type. > > > On Sep 24, 2011, at 8:07 AM, Dmitry N.
