[cfe-dev] clang failing to link with LLVM objects (sparc/SunOS)

[Alex Heinz]

I'm attempting to compile LLVM and clang on a Sparc machine from the LLVM
2.9 Release source code, and while LLVM seems to be building correctly,
clang is failing at link time with a huge number of undefined symbols that
appear to reference LLVM objects:

[snip]
llvm[4]: Compiling cc1_main.cpp for Release build
llvm[4]: Compiling cc1as_main.cpp for Release build
llvm[4]: Compiling driver.cpp for Release build
llvm[4]: Linking Release executable clang (without symbols)
Undefined                       first referenced
 symbol                             in file
llvm::Function::hasGC() const
/home17/aheinz/Documents/Misc/llvm-clang/build/Release/lib/libLLVMBitWriter.a(BitcodeWriter.o)
llvm::sys::path::is_absolute(llvm::Twine const&)
/home17/aheinz/Documents/Misc/llvm-clang/build/Release/lib/libclangFrontend.a(InitHeaderSearch.o)
llvm::CallInst::init(llvm::Value*, llvm::Value* const*, unsigned int)

llvm::Value*, llvm::Twine const&, llvm::Instruction*)

llvm::Regex::match(llvm::StringRef, llvm::SmallVectorImpl<llvm::StringRef>*)
/home17/aheinz/Documents/Misc/llvm-clang/build/Release/lib/libclangFrontend.a(VerifyDiagnosticsClient.o)
[snip] (there are a very large number of similar such errors)

It appears as though the linker can't find any of the LLVM symbols. Has
anyone seen this before? Is there something I need to change in a makefile /
my config options / my path / etc. to correct this? I've been googling all
day to no avail.

Help appreciated,
