build errors on GCC 10 (gfortran)

[dpgarrick]

GCC10 is the default on Ubuntu 22.04.

During the build step there are many compilation errors of the form:

scalapack/SRC/pstrord.f:3264:54:

  490 |      $         CALL IGAMX2D( ICTXT, 'All', TOP, 1, 1, MMAX, 1, -1,
      |                                                      2
......
 3264 |                CALL IGAMX2D( ICTXT, 'All', TOP, 1, 1, INFO, 1, -1,
      |                                                      1
Error: Rank mismatch between actual argument at (1) and actual argument at (2) (rank-1 and scalar)

See this link for the explanation and the fix.

Until the code is fixed the workaround is to configure cmake with the following flag: -DCMAKE_Fortran_FLAGS="-fallow-argument-mismatch" which converts the error into a warning.

e.g.

mkdir -p build && cd build && cmake -DCMAKE_Fortran_FLAGS="-fallow-argument-mismatch" .. && make scalapack

Thanks for the observation and for the workaround!

Just to repeat what is in your link: GCC 10 now rejects argument mismatches occurring in the same source file.

Same issue on gcc-11.3.0. Thanks for workaround.

Hi All,

Following on from the above, I'm trying to build ScaLAPACK 2.2.0 around gcc 11.2.0.

I've run the following cmake command to include the Fortran flags which were causing the errors mentioned above to start with. This seems to do part of the job for me now, producing warnings as predicted.

cmake ../CMakeLists.txt -DCMAKE_Fortran_FLAGS="-fallow-argument-mismatch" -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/install/path -DCMAKE_VERBOSE_MAKEFILE=ON

However, upon running

make -j 16 > make.out 2> make.err

I get the following errors and I'm not sure how to proceed.

I have modules loaded for openblas 0.3.28, openmpi 4.1.3, libxc 6.2.2 and fftw 3.3.10 all build around gcc 11.2.0

If this should be a new issue, please let me know.

Thanks,
