[cfe-dev] Clang API and __builtin_va_list definition

[Kamaljit Lall]

I am using the Clang c++ API. I have a blocking issue because the builtin __builtin_va_list clang isn't defined.



Here is the error:



..lib/clang/3.2/include/stdarg.h:30:9: error: unknown type name '__builtin_va_list'; did you mean '__builtin_va_list'? typedef __builtin_va_list va_list;



>From what I've read, this builtin is target dependent.



This builtin is not defined in Builtins.def or BuiltinsX86.def or anywhere else I can find in the clang source code.



I am on a Redhat Linux box.



How can I get this builtin to be visible? Do I have to supply it myself?



I missing something in my Clang C++ API usage it seems to me.



All the other builtins seem to be installed and working.
