Hello Thomas, this error typically occurs when different compiler suites used for compiling C/C++ mixed source code. Please add CXX=icpc to your configure command in order to use a single compiler suite (=Intel) for compiling Open MPI. Otherwise, CXX is set to the default compiler (=g++) which isn't suitable for linking objects generated by the Intel compiler. Regards, Matthias
