environment settings

[Mark Brethen]

(resent with correction)

I’m using the compilers group with

compilers.choose    cc f77
compilers.setup     require_fortran

below is the env settings:

:debug:configure Environment: 
:debug:configure CC='/usr/bin/clang'
:debug:configure CC_PRINT_OPTIONS='YES'
:debug:configure CC_PRINT_OPTIONS_FILE='/opt/local/var/macports/build/_Users_marbre_ports_math_taucs/taucs/work/.CC_PRINT_OPTIONS'
:debug:configure CFLAGS='-pipe -Os -arch x86_64'
:debug:configure CPATH='/opt/local/include'
:debug:configure CPPFLAGS='-I/opt/local/include'
:debug:configure CXX='/usr/bin/clang++'
:debug:configure CXXFLAGS='-pipe -Os -stdlib=libc++ -arch x86_64'
:debug:configure F77='/opt/local/bin/gfortran-mp-8'
:debug:configure F77FLAGS='-m64'
:debug:configure F90FLAGS='-pipe -Os -m64'
:debug:configure FCFLAGS='-pipe -Os -m64'
:debug:configure FFLAGS='-pipe -Os'
:debug:configure INSTALL='/usr/bin/install -c'
:debug:configure LDFLAGS='-L/opt/local/lib -Wl,-headerpad_max_install_names -arch x86_64'
:debug:configure LIBRARY_PATH='/opt/local/lib'
:debug:configure MACOSX_DEPLOYMENT_TARGET='10.12'
:debug:configure OBJC='/usr/bin/clang'
:debug:configure OBJCFLAGS='-pipe -Os -arch x86_64'
:debug:configure OBJCXX='/usr/bin/clang++'
:debug:configure OBJCXXFLAGS='-pipe -Os -stdlib=libc++ -arch x86_64'

for this particular port, I need to override the build and pass F77 as the linker. I tried

build.args-append   CC=${configure.cc} \
                   F77=${configure.f77}

build.target        lib/${os.platform}${os.major}/libtaucs.a

build {
   ui_info "Building libtaucs archives:"
   system -W ${worksrcpath} "${build.cmd} ${build.args} ${build.target}"
}

with 'LD = $(F77)’ in the Makefile, but that didn’t work. How should I pass this during build?
