Compiling gcc-trunk r278783M on MacOS Catalina (10.15.1) fails.
The configure -line (in an out-of-source-build):
OSX_SDK_VERSION=`xcodebuild -showsdks | grep 'macOS\ 10' | cut -f2- -d'-' | cut
-f2 -d' '`
OSX_SDK_PATH=`xcodebuild -sdk $OSX_SDK_VERSION -version | grep -E '^Path: ' |
cut -f2 -d' '`
../configure --prefix=$PWD/usr --enable-bootstrap
--enable-languages=c,c++,fortran,jit,lto --enable-host-shared --enable-multilib
--with-sysroot=$OSX_SDK_PATH --disable-werror
(please note, this is with & without --disable-werror)
In stage 2 it fails with:
