Hi Salvatore, I've run into similar error messages occasionally. I've never been able to fully track down the cause, but it seems to happen if I change the content of a derived type (e.g. add some new variable to it), recompile the module containing it, but don't recompile some other module that USEs that first module. It seems like there are then multiple definitions of the derived type (from different modules) that are out of sync. So, recompiling everything resolves this issue for me.
But, as I said, I'm not 100% sure that this is the explanation! -Andrew On Monday, October 17, 2022 2:28:33 AM PDT Salvatore Filippone via Fortran wrote: > Dear all > I am getting the following error message, which I find quite confusing > > 68 | use amg_prec_mod > > | 1 > > Fatal Error: Mismatch in components of derived type > '__vtype_psb_c_par_mat_mod_Psb_c_par_mat_type' from 'psb_c_par_mat_mod' at > (1): expecting 'bldext', but got 'aclsum' > compilation terminated. > > from > mpifort -v > mpifort for MPICH version 3.4.3 > Using built-in specs. > COLLECT_GCC=/opt/gnu/12.1.0/bin/gfortran > COLLECT_LTO_WRAPPER=/opt/gnu/12.1.0/libexec/gcc/x86_64-pc-linux-gnu/12.1.0/l > to-wrapper Target: x86_64-pc-linux-gnu > Configured with: ../gcc-12.1.0/configure --prefix=/opt/gnu/12.1.0 > --enable-languages=c,c++,fortran > Thread model: posix > Supported LTO compression algorithms: zlib > gcc version 12.1.0 (GCC) > > > What might the compiler be complaining about?
