[cfe-dev] cross-compilation llvm/clang 3.4 for ios simulator

[Anton Smirnov]

hey, guys.

i'm trying to cross-compile llvm/clang 3.4 for ios simulator:

export
CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
-arch i386 -Wno-extended-offsetof -miphoneos-version-min=5.0
-I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/include
-isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk"

export
CPP="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cpp"

export
AR="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar"

export LDFLAGS="-arch i386 -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk
-miphoneos-version-min=5.0 -stdlib=libc++"

../llvm_34_ios/configure
--prefix=/Users/asmirnov/Documents/dev/src/llvm_34_ios_i386_installed
--enable-optimized --disable-assertions

unset CC CXX CPP

make VERBOSE=1 -4

after compilation for about 10 minutes i'm getting an error:

clang: error: invalid argument '-mmacosx-version-min=10.9' not allowed with
'-miphoneos-version-min=5.0'

here is the full compilation command line:

clang: error: invalid argument '-mmacosx-version-min=10.9' not allowed with
'-miphoneos-version-min=5.0'

Note that '-mmacosx-version-min=10.9' was absent in my script and it was
appended by toolchain probably.

How to fix/walk-around it? Any thoughts are highly appreciated.

Regards, Anton.
