Compiling SVN-wxMax on Vista Ultimate/32

I've successfully compiled wxWidgets, but wxMax on Vista in VMWare Fusion gives me this:

How can I fix this?
(And I promise I'll have more questions tomorrow, when I'll be compiling wxMax on Ubuntu 8.04, also in VMWare Fusion.)

Ah.... yes. Building on Win32 requires a bit more effort these days, since I've added the graphics context stuff.

You need to compile wxWidgets with the graphics context enabled.

So you'll need this : http://wxmax.googlecode.com/files/gdiplus_headers.zip
(these come from the Windows SDK, which I had to install and find first... which also had to be "tweaked" in order to work)
Oh, there's also something important to *fix* in wxWidgets itself, which I appear to have neglected to write down anywhere... but you'll find it when you try to compile. (I vaguely remember something to do with an abs() call which needs to be changed to absf() or fabs()....)

Which you can extract to *somewhere* in an included folder. I generally just dump it into my MinGW/include dir.
It's only required for building wxWidgets, so we don't need it specifically for wxMax.

Why do we want wxGCDC and wxGraphicsContext? Well, it gives us some improved GDI drawing on Win32 - like antialising and alpha - which gets it up to the same standard as Mac and Linux.


Yeah, I *really* need to update my build notes :-p

In msw/graphics.cpp, you will need to edit this:

void wxGDIPlusPathData::AddArc( wxDouble x, wxDouble y, wxDouble r, double startAngle, double endAngle, bool clockwise )
{
    double sweepAngle = endAngle - startAngle ;
    if( abs(sweepAngle) >= 2*M_PI)
    {
...

and change the abs to fabs...

void wxGDIPlusPathData::AddArc( wxDouble x, wxDouble y, wxDouble r, double startAngle, double endAngle, bool clockwise )
{
    double sweepAngle = endAngle - startAngle ;
    if( fabs(sweepAngle) >= 2*M_PI)
    {
...

Weird. I didn't change any source files, but it compiled anyhow now.

BUT I am getting this, which does not really surprise me, because there is no gdiplus.dll anywhere on my Vista VM:

Building aui
Compiling:aui.bmx
flat assembler  version 1.67.26  (1155308 kilobytes memory)

Linking:aui.exe
C:/Program Files/BlitzMax/bin/ld.exe: cannot find -lgdiplus
Build Error: Failed to link C:/Program Files/BlitzMax/mod/wx.mod/samples/aui.exe
Process complete

By the way, my other VM is currently building wx on Ubuntu 8. It was a pain in the $/(!" to find all those libs and dependencies and whatever else.

Ok. Building wxMax on Ubuntu 8 fails with one million or so error messages. I can't even scroll up to the beginning of them in the Terminal window.

I can't for the life of my understand why some people like Linux. Nothing. Ever. Works. Then again, maybe that's exactly the reason why; it's like fixing that Harley Davidson every single day...

Well, that's a bummer...

Perhaps you can leave out

Import "-lgdiplus"

from wx.mod/common.bmx

:-/

Assuming everything is in the right place, and you are using the same version of gcc to build both, I wouldn't expect too many errors.

I just tried removing the Import from my XP build, and it don't like it at all...

Which is a bit of a shame.


If you can confirm it works for you without the Import, then at least that's something to work on, otherwise I may as well remove the feature for Win32 altogether.

It probably is just one error somewhere, but it shows me dozens of "wxglue.cpp: error: syntax error" messages, and there are so many of them that I cannot see with what it starts.

By the way, after applying the source code change above, I am now getting errors compiling wxWidgets on Windows. Stuff like "GdiplusShutdown" was not declared in this scope and "expected primare-expression before )" and so on. How can that happen after changing only one letter?

Perhaps Vista doesn't require that "fix", which was certainly needed on XP to get it to compile here.

Ho hum...

Oh, I guess it was just me, Mr Smarty... It didn't find the gdiplus headers - I had them in a sub directory named "gdiplus_headers" in MinGW's include folder, and it didn't look for them there.

After fixing that, I got the compiler error for which you posted the fix up there.

Now it compiled.

Max still complains about the missing -lgdiplus. I am now recompiling it without the Import statement.

Ok, the Vista build now works!!

Going back to Linux...

Ah! I forgot to copy setup.h to include/wx. Now it compiles on Linux as well.

Without the Import?

Dunno how I'm going to fix that then... cuz it's definitely required for < Vista....

Yes, without the Import.

I don't know, maybe Mark can add a ?Vista condition flag... There are so many differences between pre-Vista systems and Vista, it would probably come in handy in many situations.

Well, with my BMK-NG, I could probably hack something up to do it based on your current OS version, but I really don't want to go back to having to rely on a non-default BMK at this time.

I guess for now, I add notes : if you are building on Vista, comment out this...

No big deal, I suppose.

Ahh, I may have solved the problem... or, I should probably do as Homer Simpson... D'oh!

GCC likes .a files for dlls, a link time. You probably don't have the libgdiplus.a file, and hence it complains about -lgdiplus.

Mind you, without the file, I would expect you to get link errors. Which implies your wxWiddgets build settings are not including GDI+ integration.

Anyhoo, there's a libgdiplus.a file available in the win32 static libs distribution.
Come to think of it, that file probably wants to be included in the headers release too - just in case someone wants to build with it :-p

Adding that file (to the win32/lib dir) should fix your build problem.

*sigh*... this is what happen when one fails to keep ones notes in order ;-)

Um, I think it is configured to use GDI Plus, at least I changed the settings in two files from 0 to 1, so it -should- use it. I don't have the VM running right now; when I do, I can post the files here and check once more.

Heh... I just kicked mine off to have a peek in the lib folder, as I had a horrible feeling that this was the reason... and there it was, libgdiplus.a, sitting there at the top...

Funny thing is, I don't even remember building that file from the dll... which I would have had to do... I think I need a holiday :-p

Here's what my config.gcc says:

# Link with gdiplus.lib? (Needed for wxGraphicsContext, will also set wxUSE_GRAPHICS_CONTEXT) [0,1]
USE_GDIPLUS := 1

And that's the relevant part in setup.h:

// Enable the new wxGraphicsPath and wxGraphicsContext classes for an advanced
// 2D drawing API.  (Still somewhat experimental)
//
// Please note that on Windows you will need to link with gdiplus.lib (use
// USE_GDIPLUS=1 for makefile builds) and distribute gdiplus.dll with your
// application if you want it to be runnable on pre-XP systems.
//
// Default is 0
//
// Recommended setting: 1
#ifndef wxUSE_GRAPHICS_CONTEXT
#define wxUSE_GRAPHICS_CONTEXT 1
#endif

And these are the GDIPlus.dll files on my Vista VM:

Somehow I have the feeling that none of them are actually used by or related to wxWidgets.
