GFortran 10 Argument Mismatch

Opened this issue · 2 comments

Just as in ADIOS2: ornladios/ADIOS2#2228

@michaelkuhn reported an issue in Spack, which indicated that ADIOS needs the Fortran compiler flag -fallow-argument-mismatch flag in order to build with GCC/GFortran 10.

Note:

Using this option is strongly discouraged. It is possible to provide standard-conforming code which allows different types of arguments by using an explicit interface and TYPE(*).

Describe the bug
Please see spack/spack#16569

To Reproduce
s. above

Desktop (please complete the following information):

  • OS/Platform: Ubuntu
  • Build: GCC 10
  • ADIOS version: 1.13.1

Additional context
See: spack/spack#16569

Yeah, I just hit this as well; I couldn't figure out a robust fix. My workaround was just

FCFLAGS="-g -O2 -fallow-argument-mismatch" ./configure

which I suppose is fairly obvious to anyone who works with configure scripts with any regularity. (Not me!)

Yes, We were wondering if there is an actual change that we can implement in the code to address the raised diagnostics instead of muting it.
