[Solved][1.9] Mingw5.3 32bits GetModuleHandleEx

[Suryavarman]

I try to build ogre 1.9 with my gdeps project :
http://gdeps.org/
https://sourceforge.net/p/gdeps/mercuri ... re/ogre.py

At the moment i have this error to solve with Mingw 5.3 32bits (see http://www.mingw.org )

E:\..\GDeps\trunk\Projects\ogre\ogre\OgreMain\src\WIN32\OgreConfigDialog.cpp|49|error: 'GetModuleHandleEx' was not declared in this scope|

For this mingw version i have the winbase.h

Code: Select all

#if (_WIN32_WINNT >= 0x0501)
WINBASEAPI BOOL WINAPI GetModuleHandleExA(DWORD,LPCSTR,HMODULE*);
WINBASEAPI BOOL WINAPI GetModuleHandleExW(DWORD,LPCWSTR,HMODULE*);
#endif

...

#if (_WIN32_WINNT >= 0x0501)
#define GetModuleHandleEx GetModuleHandleExA
#endif

To understand why, i would to know, where is the #include to include winbase.h ?

[Suryavarman]

I have find the includes path:

OgreMain\src\WIN32\OgreConfigDialog.cpp

#include "OgreConfigDialog.h"

OgreMain\include\OgreConfigDialog.h

#elif OGRE_PLATFORM == OGRE_PLATFORM_WIN32
# include "WIN32/OgreConfigDialogImp.h"

OgreMain\include\WIN32\OgreConfigDialogImp.h

#include <windows.h>

x:\MinGW\include\windows.h

#include <winbase.h>

I think i have find the problem but not the why ?

I'm on windows 7:

on c:\MinGW\include\sdkddkver.h the value for windows 7 it's that:

Code: Select all

#define _WIN32_WINNT_WIN7	0x0601	

But the value for _WIN32_WINNT it's 0x0500 (windows 2000)

Code: Select all

#ifndef _WIN32_WINNT
# ifdef WINVER
#  define _WIN32_WINNT WINVER
# else
#  ifdef _WARN_DEFAULTS
#   warning "Assuming default setting of _WIN32_WINNT_WIN2K for _WIN32_WINNT"
#  endif
#  define _WIN32_WINNT _WIN32_WINNT_WIN2K
# endif
#endif

In sdkddkver.h I haven't find a line with

Code: Select all

define _WIN32_WINNT _WIN32_WINNT_WIN7

I have find the origin.
ogre\CMakeLists.txt
line 144:

Code: Select all

if (MINGW)
  add_definitions(-D_WIN32_WINNT=0x0500)
  # set architecture to i686, since otherwise some versions of MinGW can't link
  # the atomic primitives
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=i686")
  # Fpermissive required to let some "non-standard" casting operations in the plugins pass
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fpermissive")
  # disable this optimisation because it breaks release builds (reason unknown)
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-tree-slp-vectorize")
  # Ignore some really annoying warnings which also happen in dependencies
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-error=cast-qual -Wno-unused-local-typedefs")
endif ()

Now i call cmake with -D_WIN32_WINNT = 0x0501 (windows xp) and not with windows seven value to keep the compatibility with XP and vista.


EDIT:
Error....
ogre\CodeBlocks\Mingw_32\release_dynamic\CMakeCache.txt

Code: Select all

//No help, variable specified on the command line.
_WIN32_WINNT:UNINITIALIZED=0x0501

EDIT:
Ok i'm stupid it's just an add_defitions without cmake variable. It's a bug from ogre CMakelists.txt. I'm oblige to edit the CMakeLists.txt.
