We found the problem. We made some changes to the default compile line for xlf so that our users don't have to type long compile lines. We edited the file: /etc/opt/ibmcmp/xlf/12.1/xlf.cfg and appended this line to the xlf90 sections: options= -qfree=f90,-q64,-qextname,-qarch=auto,-qtune=

I don't know if anyone has tried the xlf compilers in a long time; it's probably unsurprising that they don't work. :-( However, if you can handle not having the Fortran 90 bindings, you might be able to eek by with the --disable-mpi-f90 option to configure. On Jan 13, 2009, at 12:03 AM,

Hi, I am trying to compile openmpi-1.2.8 on an IBM Power6 box using the xlc and xlf compilers. Here is my configure line: ./configure CC=xlc_r CXX=xlc++_r F77=xlf_r FC=xlf90_r --disable-shared --enable-static When I type make the build stops with the following error. Anyone have any ideas as to
