I strongly disagree. Clang works excellently. Here's my way to build NetBSD
(does not need command line tools being installed, Xcode in /Applications is
sufficient):
#!/bin/csh
set MACHINE=amd64
set DIST=${cwd}
set SRCDIR=${cwd}/src
set TOOLDIR=${cwd}/tools
set X11SRCDIR=${cwd}/xsrc
set OBJDIR=obj.${MACHINE}
set JOBS=`sysctl -n hw.ncpu`
set BUILD="./build.sh -j${JOBS} -U -N0 -u -x -X${X11SRCDIR} -m${MACHINE}
-T${TOOLDIR} -O${OBJDIR}"
set XCODE=/Applications/Xcode.app/Contents/Developer
set HOST_CFLAGS=-O2\ -pipe\ -march=core2\ -fomit-frame-pointer\
-fno-stack-protector
set HOST_CPPFLAGS=-isysroot\
${XCODE}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
set
HOST_LDFLAGS=-Wl,-syslibroot,${XCODE}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
set HOST_CC=${XCODE}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
set HOST_CXX=${XCODE}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++
cd ${SRCDIR}
${BUILD} -V HOST_CC="${HOST_CC} ${HOST_CPPFLAGS}" -V HOST_CXX="${HOST_CXX}
${HOST_CPPFLAGS}" -V HOST_CPPFLAGS="${HOST_CPPFLAGS}" -V
HOST_CFLAGS="${HOST_CFLAGS}" -V HOST_CXXFLAGS="${HOST_CFLAGS}" -V
HOST_LDFLAGS="${HOST_LDFLAGS}" release
Kind regards,
Adam
