I checked and found PetscComplex was correctly defined to std::complex, and clang-6.0 was also fine to use GNU C++ library. The problem was the gcc-4.8.5 C++ library clang picked up was a bit old, which conformed to C++11. However clang-6.0's default uses C++14, which changed the rules of *constexpr.* Workarounds include: - define PETSC_SKIP_CXX_COMPLEX_FIX in the offending *.cxx file. - add CXXOPTFLAGS=-std=c++11 - update clang-6.o or gcc-4.8.5 (of 2015) on that machine. --Junchao Zhang On Fri, May 14, 2021 at 10:42 AM Satish Balay <balay(a)mcs.anl.gov> wrote: > You can login to: isdp001.cels.anl.gov - using your MCS account > credentials [and then setup ~/.ssh/authorized_keys] > > Satish > > On Fri, 14 May 2021, Junchao Zhang wrote: > > > Satish, how to access this machine?

Problem with the reorganization of complex with clang
by Matthew Knepley 13 May '21

In this CI run (linux-clang-avg): https://gitlab.com/petsc/petsc/-/jobs/1260342204 The compile fails building a C++ file, demangle.cxx. It fails at the first line, including <petsc/private/petscimpl.h>, down in petscsystypes.h. It bombs during the definition of complex because it looks like the compiler is not defining __cplusplus, and thus takes the wrong branch. Is this what is happening? I cannot access this machine.
