Hi,
I've got a program using libclang to compile C/C++ scripts at run-time.
When trying to use it with libstdc++, specifically <string>, although I
get similar errors when using other standard headers, I get errors of
the form "use of undeclared identifier '__builtin_clz'; did you mean
'__builtin_clz'?" or "unknown type name '__builtin_va_list'; did you
mean '__builtin_va_list'?"
I've checked the list of identifiers to see that __builtin_clz (and
others that it's complaining about) are in there, and __builtin_va_list
is defined in the ASTContext.
The full code for how I've set up and am calling the compilation are at
http://pastebin.com/SASu4xMi and the output from clang::ParseAST when
including <string> is at http://pastebin.com/UphYaNj8 . Despite the
outside saying that those builtins exist, using the program at
http://pastebin.com/UphYaNj8 says that the builtins don't exist at
compilation time.
Cheers,
Rohan Smith
