Hi

I tried building charm++ (v6.8.2) on my laptop with macOS Sierra. I used the
following build command,

CC=gcc-8 CXX=g++-8 FC=gfortran ./build AMPI multicore-darwin-x86_64 gcc
gfortran --enable-ampi-error-checking --enable-charmdebug

I installed gcc-8 using homebrew and have disabled SIP.

The build process said it finished successfully. But when I tried to compile
a simple test program using ampif90 I got the following errors,

$> ampif90 test.f90 -o test
...
ld: warning: could not create compact unwind for _AMPI_Send: dwarf uses
DW_CFA_GNU_args_size
ld: warning: could not create compact unwind for _AMPI_Ssend: dwarf uses
DW_CFA_GNU_args_size
...

And when I tried running the generated executable it just segfaults. Any idea
what could be wrong?

Regards,
