Hello List,
I've built llvm/clang 3.2 for the x86 architecture only by specifying
LLVM_TARGETS_TO_BUILD=X86 . I then proceeded to write a program based on
clang to parse a source file. Unfortunately it seems the target being
used is x86 32 bit as the diagnostics are outputting the following error:
/usr/include/x86_64-linux-gnu/gnu/stubs.h:7:11: fatal error: 'gnu/
stubs-32.h' file not found
Having looked in Base/Targets.cpp it seems to all depend on what
Triple.getArch() returns; Also have in vain tried to find out how clang -
the compiler - (identifies and ?) sets the correct architecture by
default.
How can I set the target options to 64 bits?
Currently doing:
llvm::IntrusiveRefCntPtr<TargetOptions> pto(new TargetOptions());
pto->Triple = llvm::sys::getDefaultTargetTriple();
TargetInfo *pti = TargetInfo::CreateTargetInfo(ci.getDiagnostics(),
*pto);
ci.setTarget(pti);
The contents of pto->Triple are: x86_64-unknown-linux-gnu
