For ex: git clone https://github.com/spack/spack/ cd spack ./bin/spack install gcc@7.5.0 Satish On Sat, 30 Sep 2023, Pierre Jolivet wrote: > You are using g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23). > You need to use a less ancient C++ compiler. > Please send logs to petsc-maint, not petsc-users. > > Thanks, > Pierre > > > On 30 Sep 2023, at 7:00 AM, Ivan Luthfi <ivanluth...@gmail.com> wrote: > > > > I am trying to configure my pets-3.13.6, but I have an error when running > > configure on cmake.
