--- Comment #2 from Sam James <sjames at gcc dot gnu.org> --- ``` mkdir /tmp/fortran && cd /tmp/fortran # Unfortunately, we have to install at least one library, so we do it in /tmp/fortran/prefix to keep it off the real system. mkdir /tmp/fortran/prefix git clone https://github.com/ecmwf/ecbuild export PATH="/tmp/fortran/ecbuild:${PATH}" git clone https://github.com/ecmwf/eckit cmake -B build -S . -DCMAKE_INSTALL_PREFIX=/tmp/fortran/prefix make -C build -j$(nproc) -l$(nproc) make -C build -j$(nproc) -l$(nproc) install cd /tmp/fortran git clone https://github.com/ecmwf/fckit # This will fail because of PR118789. Workaround is to use gfortran-14, like: # FC=gfortran-14 CC=gcc-14 CXX=g++-14 FFLAGS="-O2" CFLAGS="-O2" CXXFLAGS="-O2" cmake -B build -S . -DCMAKE_INSTALL_PREFIX=/tmp/fortran/prefix FFLAGS="-O2" CFLAGS="-O2" CXXFLAGS="-O2" cmake -B build -S . -DCMAKE_INSTALL_PREFIX=/tmp/fortran/prefix make -C build -j$(nproc) -l$(nproc) make -C build -j$(nproc) -l$(nproc) install cd /tmp/fortran git clone https://github.com/ecmwf/atlas cd atlas # If this fails, you can try disable more arguments.
