this is how I usually do it under ubuntu22
export CC="/usr/bin/clang"
export CXX="/usr/bin/clang++"
export PREFIX="/usr"
export
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:${PREFIX}/bin"
export PKG_CONFIG_PATH="/usr/lib/pkgconfig/:/usr/local/lib/pkgconfig/"
export RUNTIME_VERSION="gnustep-2.1"
export OBJCFLAGS="-fblocks"
export CFLAGS="-I ${PREFIX}/include"
export LDFLAGS="-fuse-ld=gold"
export GNUSTEP_INSTALLATION_DOMAIN="SYSTEM"
cd libobjc2
git submodule init
git submodule update
mkdir Build
cd Build
/usr/bin/cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DOLDABI_COMPAT=OFF
-DBUILD_STATIC_LIBOBJC=1 -DCMAKE_C_COMPILER=${CC} -DCMAKE_CXX_COMPILER=${CXX}
-DCMAKE_INSTALL_PREFIX=/usr -DGNUSTEP_CONFIG:FILEPATH=GNUSTEP_CONFIG-NOTFOUND
OLDABI_COMPAT=OFF
make
make install
this is before gnustep-make is even installed
