So some good new! After updating my installed packages it turns out that version updates of gcc versions 4-8 now allows for the successful compilation of AmberTools (and amber?) using the gnu gcc compilers on macOS 10.14.4 and Xcode 10.2.1
However, as the homebrew versions of both openMPI and mpich somehow depends on clang, I have yet found a way to successfully perform the parallel compilation. Compilation using either openMPI or mpich terminates with the following error:
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [/Users/guolaa/SOFTWARE/amber18/bin/mdgx.MPI] Error 1
make[1]: *** [parallel] Error 2
make: *** [install] Error 2
With the "clang: error:” part probably being the issue. So for both openMPI and mpich, the following warning is presented:
Warning: mpich/open-mpi dependency gcc was built with a different C++ standard
library (libstdc++ from clang). This may cause problems at runtime.
and 'mpirun —version’ for mpich provides the following output:
HYDRA build details:
Version: 3.3
Release Date: Wed Nov 21 11:32:40 CST 2018
CC: clang
CXX: clang++
F77: gfortran
F90: gfortran
Regardless of any symlink/env/export bypass I have tried I cannot seem to get around ‘clang’ for the MPI compilation though I suspect this is just a matter of effort. Possiblest re-compiling openmpi/mpich from source using gnu gcc.
Rounding up, clang serial and clang+openMPI/mpich parallel works while gnu gcc4-8 serial works however parallel does not work without further configuration on the latest versions of macOS and Xcode using homebrew as package manager. I will update the website accordingly as soon as I have some time.
