Summary

0008068: gccxml fails to parse MSVC9 STL with -D_DEBUG

Description

Hi,

the following file
$ cat v.h
#include <vector>
cannot be parsed with the current trunk when selecting the debug STL implementation of MSVC9:
$ gccxml v.h -fxml=v.xml -D_DEBUG
In file included from C:/Program Files/Microsoft Visual Studio 9.0/VC/include/utility:6,
                 from F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/xutility:7,
                 from F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/iterator:6,
                 from F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/memory:6,
                 from F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/vector:6,
                 from v.h:1:
F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/iosfwd: In static member function 'static _Elem* std::char_traits<_Elem>::_Copy_s(_Elem*, size_t, const _Elem*, size_t)':
F:/root/gccxml-2008-08-11-vc9/GCC_XML/Support/Vc9/Include/iosfwd:253: error: there are no arguments to '__debugbreak' that depend on a template parameter, so a declaration of '__debugbreak' must be available

and many more. (Never mind the dir name of GCCXML in above example - it _is_ the current trunk.) I need to parse the debug version because it is binary incompatible with the release implementation. Hurray. Any chance of fixing that?

Cheers, Axel.

(0014080) Brad King (manager) 2008-11-10 08:58	Yes, of course, but I won't be able to get to it for a while. If you need a solution right away I suggest trying to fix it yourself (and I'll put a patch in when I get time to work on it). Many of the headers I had to patch had this error for the release version. I thought I did the debug ones too. Is this a service pack or something? Anyway, you should find the declaration or definition of the missing templates elsewhere in the MS headers. Just copy it to create a forward declaration at the top of iosfwd or whatever header is complaining. Basically ths MS header has invalid C++ code but their compiler is okay with it.

(0014084) axel (reporter) 2008-11-10 13:47	No service pack, int'l version, nothing special. And I think you did add the decls - it still uses an undeclared intrinsic and a funny widened version of __FUNCTION__. Attached patch crtdbg.h.diff works for me.

(0014266) axel (reporter) 2008-12-02 06:54	Hi Brad, any chance of getting this patch into the repository? Cheers, Axel.

(0014352) Brad King (manager) 2008-12-15 15:43	I've applied a similar patch and re-generated the patch gccxml applies on installation: /cvsroot/GCC_XML/gccxml/GCC_XML/VcInstall/vc9Include.patch,v <-- GCC_XML/VcInstall/vc9Include.patch new revision: 1.3; previous revision: 1.2
