[cfe-dev] problem embedding clang 2.7 (__builtin_fabsf not found) - confused!

Wed Jun 2 19:56:53 PDT 2010

Hi,

I'm trying to embed Clang 2.7 into a tool driven by Lua. I had this working fine with 2.6, but am having problems with 2.7: some builtins appear to not be found. Including <math.h> leads to errors such as:

error (/usr/include/architecture/i386/math.h): use of undeclared identifier '__builtin_fabsf'

I printed out the list of builtins used by context, and __builtin_fabsf is in that list:

		llvm::SmallVector<const char *, 32> BuiltinNames;
		Ctx.BuiltinInfo.GetBuiltinNames(BuiltinNames, Ctx.getLangOptions().NoBuiltin);
		for (int i = 0; i<BuiltinNames.size(); i++) {
			printf("Builtin %s\n", BuiltinNames[i]);		//--> list includes '__builtin_fabsf'
		}

Also, if I disable C++ in the LangOptions, incuding "stdarg.h" leads to errors about 'redefinition of va_list'. 

I'm including the lib/clang/1.1/include path, so these headers are being found. 

It's hard to know what else to try - I've been banging on this all day and can't figure it out - any help would be *much* appreciated!

here's the main code driving the compilation - if anything here looks unusual let me know!:

		std::string unitsrc = ... // source code to compile is entered at runtime.

		// Souce to compile
		llvm::MemoryBuffer *buffer = llvm::MemoryBuffer::getMemBufferCopy(unitsrc.c_str(), unitsrc.c_str() + unitsrc.size(), unitname.c_str());
		if(!buffer) {
			luaL_error(L, "couldn't load %s", unitsrc.c_str());
		}

		clang::TargetInfo * target = clang::TargetInfo::CreateTargetInfo(diags, targetopts);

		... and on to error handling etc.

This is using LLVM/Clang 2.7 release, built on Mac OS 10.6, with the following ./configure/make invocation (I need to support OS 10.5+ and 32/64 bit universal):

env MACOSX_DEPLOYMENT_TARGET=10.5 ./configure --enable-targets=x86,x86_64 --enable-jit --enable-optimized --enable-pic
env MACOSX_DEPLOYMENT_TARGET=10.5 sudo make DARWIN_VERSION=10.5 UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" UNIVERSAL_SDK_PATH=/Developer/SDKs/MacOSX10.5.sdk/
