This is the contents of config.log with the same substitution as before. It APPEARS that the problem is invalid command line options being passed to GCC! How do I fix this? This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by GNU Offloading and Multi Processing Runtime Library configure 1.0, which was generated by GNU Autoconf 2.64. Invocation command line was $ $HOME/Development/gcc-source/gcc-8.2.0/libgomp/configure --srcdir=$HOME/Development/gcc-source/gcc-8.2.0/libgomp --cache-file=./config.cache --enable-multilib --prefix=$HOME/gcc-built --disable-shared --disable-assembly --enable-languages=c,c++,fortran,lto,objc,obj-c++ --program-transform-name=s,y,y, --disable-option-checking --with-target-subdir=x86_64-apple-darwin17.7.0 --build=x86_64-apple-darwin17.7.0 --host=x86_64-apple-darwin17.7.0 --target=x86_64-apple-darwin17.7.0 --disable-intermodule --enable-checking=yes,types --disable-coverage --enable-languages=c,c++,lto --disable-build-format-warnings ## --------- ## ## Platform. ## ## --------- ## hostname = Bryans-iMac.local uname -m = x86_64 uname -r = 17.7.0 uname -s = Darwin uname -v = Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 /usr/bin/uname -p = i386 /bin/uname -X = unknown /bin/arch = unknown /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown /usr/bin/hostinfo = Mach kernel version: Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 Kernel configured for up to 4 processors. 4 processors are physically available. 4 processors are logically available.
