The boot compiler is GCC 12.1.0.
Configuration fails because the C compiler can’t produce an executable. I don’t have the log, but the errors were like
configure:3943: gcc -c -g conftest.c >&5
<built-in>: error: unknown value '13.0.0' of '-mmacosx-version-min'
I tried setting CFLAGS and CXXFLAGS as here:
export CFLAGS=-mmacosx-version-min=12.0.0
export CXXFLAGS=-mmacosx-version-min=12.0.0
$GCC_SRC/configure \
--prefix=$PREFIX \
--without-libiconv-prefix \
--disable-libmudflap \
--disable-libstdcxx-pch \
--disable-libsanitizer \
--disable-libcc1 \
--disable-libcilkrts \
--disable-multilib \
--disable-nls \
--enable-languages=c,c++,ada \
--host=$BUILD \
--target=$BUILD \
--build=$BUILD \
--without-isl \
--with-build-sysroot="$(xcrun --show-sdk-path)" \
--with-sysroot= \
--with-specs="%{!sysroot=*:--sysroot=%:if-exists-else($XCODE $CLU)}" \
--with-build-config=no \
--enable-bootstrap \
CFLAGS=-mmacosx-version-min=12.0.0 \
CXXFLAGS=-mmacosx-version-min=12.0.0
(having checked that this flag was needed to avoid the error in a standard-alone compilation) but the configure now failed in fixincludes/. It seems that sometimes the CFLAGS setting is used and sometimes it isn’t??? See lines 3674, 3744, 3800, 3857, 3905 below and then 3943
