SIerra: issue with assembler "as" in conjunction with gfortran

[rjones-sandia]

I've removed and reinstalled "port" $ port version Version: 2.5.3 I've only installed gcc7 at this point: $ port installed The following ports are currently installed:

bzip2 @1.0.6_0 (active) cctools @895_7+llvm50 (active) gcc7 @7.3.0_3 (active) gcc_select @0.1_8 (active) gettext @0.19.8.1_0 (active) gmp @6.1.2_1 (active) isl @0.18_0 (active) ld64 @3_1 (active) ld64-latest @274.2_2+llvm50 (active) libcxx @5.0.1_2+universal (active) libedit @20170329-3.1_2 (active) libffi @3.2.1_0 (active) libgcc @1.0_0 (active) libgcc7 @7.3.0_2 (active) libgcc8 @8.2.0_0 (active) libiconv @1.15_0 (active) libmpc @1.1.0_1 (active) libunwind-headers @5.0.1_0 (active) libxml2 @2.9.7_0 (active) llvm-5.0 @5.0.2_0 (active) llvm_select @2_0 (active) mpfr @4.0.1_0 (active) ncurses @6.1_0 (active) openssl @1.0.2p_0 (active) xar @1.6.1_0 (active) xz @5.2.4_0 (active) zlib @1.2.11_0 (active)

and I'm still getting : $ /opt/local/bin/gfortran-mp-7 test.f90 FATAL:/opt/local/bin/../libexec/as/x86_64/as: I don't understand 'm' flag!

$ which as /opt/local/bin/as

Not sure how to get around this with macports.

thanks Reese

btw removing /opt/local/bin from my PATH:

$ which as /usr/bin/as $ which gfortran /usr/local/bin/gfortran $ gfortran test.f90 $

works
