lang/gcc5 failing on macOS; which Fortran compiler?
Hi!
As far as I know, XCode on macOS does not come with a Fortran compiler. Joerg recommended I install gcc5 to get gfortran. However, the build breaks because there is no /usr/include:
if [ -d ../prev-gcc ]; then \
cd ../prev-gcc && \
/Applications/Xcode.app/Contents/Developer/usr/bin/gnumake real-install-headers-tar DESTDIR=`pwd`/../gcc/ \
libsubdir=. ; \
else \
set -e; for ml in `cat fixinc_list`; do \
sysroot_headers_suffix=`echo ${ml} | sed -e 's/;.*$//'`; \
multi_dir=`echo ${ml} | sed -e 's/^[^;]*;//'`; \
fix_dir=include-fixed${multi_dir}; \
if ! false && test ! -d `echo /usr/include | sed -e :a -e 's,[^/]*/\.\.\/,,' -e ta`; then \
echo The directory that should contain system headers does not exist: >&2 ; \
echo " `echo /usr/include | sed -e :a -e 's,[^/]*/\.\.\/,,' -e ta`" >&2 ; \
tooldir_sysinc=`echo "/opt/pkg/gcc5/lib/gcc/x86_64-apple-darwin16/5.4.0/../../../../x86_64-apple-darwin16/sys-include" | sed -e :a -e "s,[^/]*/\.\.\/,," -e ta`; \
if test "x`echo /usr/include | sed -e :a -e 's,[^/]*/\.\.\/,,' -e ta`" = "x${tooldir_sysinc}"; \
then sleep 1; else exit 1; fi; \
fi; \
/bin/sh ../../gcc-5.4.0/gcc/../mkinstalldirs ${fix_dir}; \
chmod a+rx ${fix_dir} || true; \
(TARGET_MACHINE='x86_64-apple-darwin16'; srcdir=`cd ../../gcc-5.4.0/gcc; ${PWDCMD-pwd}`; \
SHELL='/bin/sh'; MACRO_LIST=`${PWDCMD-pwd}`/macro_list ; \
gcc_dir=`${PWDCMD-pwd}` ; \
export TARGET_MACHINE srcdir SHELL MACRO_LIST && \
cd ../build-x86_64-apple-darwin16/fixincludes && \
/bin/sh ./fixinc.sh "${gcc_dir}/${fix_dir}" \
`echo /usr/include | sed -e :a -e 's,[^/]*/\.\.\/,,' -e ta` ); \
rm -f ${fix_dir}/syslimits.h; \
if [ -f ${fix_dir}/limits.h ]; then \
mv ${fix_dir}/limits.h ${fix_dir}/syslimits.h; \
else \
cp ../../gcc-5.4.0/gcc/gsyslimits.h ${fix_dir}/syslimits.h; \
fi; \
chmod a+r ${fix_dir}/syslimits.h; \
done; \
fi
The directory that should contain system headers does not exist:
/usr/include
gnumake[3]: *** [stmp-fixinc] Error 1
rm gcc.pod
gnumake[2]: *** [all-stage1-gcc] Error 2
gnumake[1]: *** [stage1-bubble] Error 2
gnumake: *** [all] Error 2
*** Error code 2
Any suggestions? Is there a supported Fortran compiler for macOS? Jonathan, which one do you use?
