Ah, ok.
I did see a curious error in your config.log:
-
12164 configure:62128: gfortran conftest.f90 -Isubdir -lz
12165 f951.exe: Fatal Error: Reading module 'ompi_mod_flag' at line 21 column
49: Unexpected EOF
12166 compilation terminated.^M
12167 configure:62135: $? = 1
-
Which looks like it failed to compile a program that used the test Fortran
module that configure created.
Specifically, the overall test is here:
https://github.com/open-mpi/ompi/blob/master/config/ompi_fortran_find_module_include_flag.m4#L36-L72
It basically does this:
1. Make a "subdir"
2. Cd into that "subdir"
3. Compile a trivial Fortran program that should emit a Fortran module
4. Cd back into ..
5. Try compiling a trivial Fortran test program that uses the module that was
just emitted, using a few different CLI options to specify the subdir where the
test Fortran module can be found
The first option -- "-I" -- seems to work, but it seems to think that the
emitted Fortran module is invalid. That's where we get that config.log error.
I admit that I'm a bit confused as to why gfortran thinks the module file is
invalid ("Unexpected EOF"). You might want to try replicating what the test is
doing manually to see if your gfortran really is emitting invalid modules...?

Re: [OMPI devel] Openmpi configure: Could not determine the fortran compiler flag
Precisely, that was the problem. I disabled Fortran support to move ahead and see if I could manage that way (and I found I couldn't!), at least in some of my uses. But I (and perhaps others as well) would still need to have Fortran support, so the issue is not moot at all.

Re: [OMPI devel] Openmpi configure: Could not determine the fortran compiler flag
For what it's worth, it looks like Open MPI's configure found your mingw fortran compiler, but was unable to determine what flag to use to find fortran modules -- that's what caused configure to abort. From your later messages, it looks like you just ended up disabling Fortran support, so this is somewhat moot, but I wanted to tie up this email thread for the archive. > On Oct 21, 2018, at 6:01 PM, Santiago Serebrinsky > wrote: > > Compiler: > $ which gfortran.exe > /mingw64/bin/gfortran.exe > > I am attaching config.log (renamed to keep track of the error produced). > > PS: To try moving further, I did > ./configure --prefix=$HOME/usr/local --disable-mpi-fortran > which led me to a later error.

Re: [OMPI devel] Openmpi configure: Could not determine the fortran compiler flag
Compiler: $ which gfortran.exe /mingw64/bin/gfortran.exe I am attaching config.log (renamed to keep track of the error produced). PS: To try moving further, I did ./configure --prefix=$HOME/usr/local --disable-mpi-fortran which led me to a later error. This is posted in a separate thread.
