config.log
I am attempting to build gcc 10.1.0 from source with Xcode 11.4.1 on macOS
Catalina 10.15.4.
I configure the build as follows:
export PREFIX=/usr/local
../configure --prefix=${PREFIX} --with-gmp=${PREFIX} --with-mpfr=${PREFIX}
--with-mpc=${PREFIX} --with-isl-prefix=${PREFIX} --with-cloog=${PREFIX}
--enable-checking=release --enable-languages=c,c++,fortran
--with-build-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
But this eventually leads to:
/lib/cpp
configure: error: in `/Volumes/ramdisk/gcc-10.1.0/build/gcc':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details
...
config.status: executing default commands
make[1]: *** [stage2-bubble] Error 2
make: *** [all] Error 2
config.log is attached.
In the config.log I see:
xgcc: error: unrecognized command-line option '-V'
and
xgcc: error: unrecognized command-line option '-qversion'; did you mean
'--version'?
But more importantly:
/Volumes/ramdisk/gcc-10.1.0/build/prev-gcc/include-fixed/limits.h:195:15: fatal
error: limits.h: No such file or directory
