Use of %ll in PropertyHelper.h doesn't play well with mingw

Postby gamecat » Tue Oct 15, 2013 04:40

I'm gettting

.../PropertyHelper.h:329:42: warning: unknown conversion type character 'l' in format [-Wformat]
.../PropertyHelper.h:329:42: warning: too many arguments for format [-Wformat-extra-args]

warnings when compiling my program using mingw with gcc 4.7.2.

This gets into the whole lame mingw MSVCRT .vs. C99 compliance issue. On my system, the program compiles and
runs ok despite the warning, but I'm worried about compatibility with other systems.


the issue is that formatter-width specifier %ll isn't supported for all msvcrt-DLL versions, therefore gcc warns about its use. The
variant for specifying 64-bit integer-scalar-width in formatter for msvcrt in a backward-compatible way is by using %I64.

I've tried using the __USE_MINGW_ANSI_STDIO macro, but it doesn't seem to help.

As far as I can tell, PropertyHelper.h is the only CEGUI file that uses %ll. Would it be possible to get some conditional thrown in?

Code: Select all

#ifdef __MINGW32__
#include <inttypes.h>

static return_type fromString(const String& str)
      uint64 val = 0;
#ifdef __MINGW32__
      sscanf(str.c_str(), " %"PRIu64"", &val);
      sscanf(str.c_str(), " %llu", &val);
      return val;

Have any of you other mingw people out there encountered this problem? If so, then how did you deal with it?

I'm tempted to try out MinGW-w64 since it has better C99 support and 64bit capability, among other things. Has anyone out there tried building CEGUI / Ogre3D / Boost with MinGW-w64? Is it more or less drop in compatible, or will I be opening another can of worms?
