Dear Open MPI support team, I am trying to install Open MPI with Intel compiler suite for the Fortran side and GNU compiler suite for the C side. For factors that don’t depend upon me, I’m not allowed to change the C compiler suite to Intel one since that would mean an additional license.
Problem arises with the fact that the installation should not dynamically depend on Intel libraries, so the flag “-static-intel” (or similar) should be passed to the Fortran compiler. I’ve seen in the FAQ that this problem is solved by passing an Autotools option “-Wc,-static-intel” to the variable LDFLAGS when invoking configure with Intel compilers. This works if both C/C++ and Fortran compilers are from Intel. However, it crashes if the compiler suite is mixed since GNU C/C++ does not recognise the “-static-intel” option. Is there any way to bypass this crash and to indicate that such option should only be passed when using Fortran compiler? Configure call to reproduce the crash is made as follows: *./configure --prefix=/usr/local/ --libdir=/usr/local/lib64/ --includedir=/usr/local/include/ CC=gcc CXX=g++ 'FLAGS=-O2 -m64' 'CFLAGS=-O2 -m64' 'CXXFLAGS=-O2 -m64' FC=ifort 'FCFLAGS=-O2 -m64' LDFLAGS=-Wc,-static-intel* Please, find attached the output from configure and config.log. Additional data: · Operating system SLES12 SP3. · Open MPI version 4.0.5 · Intel Fortran compiler version 17.0.6 · GNU C/C++ compiler version 4.8.5. I’ll very much appreciate any help provided to solve this problem. Kind regards, Álvaro
