Just an update - editing the VS6 Project Settings is trivial - a pain but trivial so I reckon this is just a simple "TODO" (or "MUSTDO") for VS 6 users.

but more VS 6 build issues

==================================

OpenThreads

==================================

Win32Thread.cpp(554) : error C2065: 'DWORD_PTR' : undeclared identifier

The line should read "DWORD res" instead of "DWORD_PTR res", as this the value returned by SetThreadAffinityMask

==================================

Producer - all 64 bit issues

==================================

Producer\PipeTimer(10) fails to compile unless defined as

    #ifdef _WIN32
    typedef          __int64 GLint64EXT;
    typedef unsigned __int64 GLuint64EXT;
    #else
    typedef long long int GLint64EXT;
    typedef unsigned long long int GLuint64EXT;
    #endif

================================

Producer/RenderSurface_Win32.cpp( 260, 279, 1379 )

    #ifdef _WIN32
                SetWindowLong(_win, GWL_WNDPROC, (LONG) _oldWndProc);
    #else
                SetWindowLongPtr(_win, GWLP_WNDPROC, (LONG_PTR)_oldWndProc);
    #endif

Producer/RenderSurface_Win32.cpp(770)

    #ifdef _WIN32
                _oldWndProc = (WNDPROC)SetWindowLong(_win, GWL_WNDPROC, (LONG) ((WNDPROC)s_proc) );
    #else
                _oldWndProc = (WNDPROC)SetWindowLongPtr(_win, GWLP_WNDPROC, (LONG_PTR)((WNDPROC)s_proc));
    #endif

================================

src\PipeTimer.cpp(128 in double PipeTimer::getElapsedTime( GLuint query )

#ifdef _WIN32

return 0.0; /* Temp fix */

#else

if( !_valid )
return 0.0;

            GLuint64EXT timeElapsed = 0;
            GLint available = 0;
            while( !available )
            {
                (*_glGetQueryObjectiv)( query, GL_QUERY_RESULT_AVAILABLE, &available );
            }

(*_glGetQueryObjectui64v)(query, GL_QUERY_RESULT, &timeElapsed );

return (double)timeElapsed*_div;
#endif

src/ConfigLexer.cpp(24)

#include <stdio.h> // to define EOF

================================

OpenSceneGraph

================================

The following .dsp files can't be loaded - all modified for VS 7 i think

freetype.dsp

ive.dsp

dot_osg.dsp

No doubt there will be a few more issues to resolve

================================

regards

Hi Mike, Robert

There is one other VS 6 gotcha - see the attached picture.

VS 6 objects to a project' General settings including environmental variables. On hitting the OK button, it erases them from the workspace and apparently from the disk since even if I cancel the settings dialog and close the workspace without saving, these variables never return.

The reality is that its not a big deal if the VS 6 build solution is to just delete the PlatformName and ConfigurationName environmental names from the workspaces.

I'll report back if any other solution appears --- just don't wait for one, since it would probably be unique to VS 6 and undo the good work put in by Mike. My preferred solution is just to make it a documentation issue and amend the README file, something along the lines of:

"VS 6 users must delete references to PlatformName and ConfigurationName environmental names from the workspace before attempting a build."

or as per Mike's suggestion, perhaps OSG could include two command (.BAT) files for 32 bit Debug and Release builds which set the variables and then invoke the compiler. Not so intuative, but this requires no changes to the various .dsp / .dsw files, except perhaps the gotcha. The users just have to remember that switching builds between Debug and Release means exiting VS 6 and invoking the alternative BAT file.

Personally I think I prefer the former, but time will tell.........

regards

Philip
