llvm dev - Nov 2009 - [LLVMdev] llvm-c: LLVMCreateExecutionEngine returning empty error message

Hello, I'm using the llvm-c bindings for C, but I'm getting some
problems,
the LLVMCreateExecutionEngine is returning 1 but the error message is an
empty string (it's !=NULL).

The steps I'm doing is to create the module, then I call LLVMVerifyModule to
verify and it works fine, later I call
LLVMCreateModuleProviderForExistingModule and it returns !=NULL MP, so it's
ok, but then when I call something like this: error_ret
LLVMCreateJITCompiler(&engine, provider, 0, &verror)
It returns 1 in error_ret and an empty string in verror, does someone knows
why or how can I get the error message ? Or when it returns an empty error
message ?
I'm using the pre built 2.6 binaries from default ubuntu karmic
installation.

Thank you,
- Christian

Just to report the answer to the problem if someone get the same problem
with llvm-c bindings:

Before calling the LLVMCreateJITCompiler, you must do:
LLVMLinkInJIT();
LLVMLinkInInterpreter();
LLVMInitializeNativeTarget();

Otherwise it will return 1 and an empty error message.
