I need to reproduce your issue on my machine to debug it. It doesn't have to be a small reproducer. Is there any way to do that?
UNFINISHED
I'll slowly write instructions here as I try to make a smallish reproducer. I'm not familiar with thge library in question which doesn't help.
I'm using GCC 14.2 greshly build from source. Next, download FEAST solver from http://feast-solver.org/ Unfortunately you have to fill in a short questionnaire.
Unpack the archive and cd to FEAST/4.0/src
Also unfortunately FEAST no longer compiles cleanly so I had to make the following change:
# gnu fortran
ifeq ($(F90),gfortran)
F90FLAGS= -O3 -fopenmp -ffree-line-length-none -ffixed-line-length-none -cpp #-fPIC
ifeq ($(MKL),yes)
F90FLAGS += -DMKL
endif
# PJF added line below
F90FLAGS += -g -fallow-argument-mismatch
endif
Build with make F90=gfortran feast
. FEAST/4.0/lib/x64 should now contain libfeast.a.
Next steps.
I'm testing using mold as a replacement for ld.bfd on a large Linux project. The build speed times look impressive.
However I am getting new failures in some of our tests.
It may be difficult to make a small reproducer. We are using
I had problems with FEAST a while back (see https://stackoverflow.com/questions/76208029/building-libfeast-eigenvalue-solver-with-gfortran) and I used the kludge -fallow-argument-mismatch
Now I'm wondering if that could be causing problems with mold?
I'm a C++ dev and I find it hard to debug fortran.
