wxGLCanvas compiling problem in simple example

Do you have a question about makefiles, a compiler or IDE you are using and need to know how to set it up for wxWidgets or why it doesn't compile but other IDE's do ? Post your questions here.

wxGLCanvas compiling problem in simple example

Post by Daniel_Cro » Tue Aug 31, 2010 9:16 am

Hello,

I have recently tried simple openGL example, but failed.
I have followed instructions:
- edited include/wx/msw/setup.h with wxUSE_GLCANVAS=1
- added USE_OPENGL=1 to command line in CodeLite project preferences under compiling (but I am not sure if this is correct)
- opengl32.lib I did NOT add !!!

I am a newbie in GUI programming and don't understand quite a lot...
To me it seems that wxWidgets does not come complete for openGL... I have downloaded glut for win32 therefore and corrected include statements in my source... no help.

When I get home, I can post the compiling errors, but I was hoping that someone probably knows what is wrong...
Basically, I have downloaded CodeLite with wxWidgets and it all works "from the box" for the "non openGL" programs. What else is needed to make simple "penguin" example work??

Thank you in advance!
Daniel

These errors simply look like you forgot

Code: Select all

#include <wx/glcanvas.h>
Now, if that's not the problem, please post the source code, if possible with annotations so we can easily see at which lines the errors are being reported

OK.

You say :
- edited include/wx/msw/setup.h with wxUSE_GLCANVAS=1
- added USE_OPENGL=1 to command line in CodeLite project preferences under compiling (but I am not sure if this is correct)
but did you rebuild wxWidgets after changing that? You will need to build wxWidgets after enabling OpenGL support

uuuuu
this is new information... no I did not recompile it...
Thank you for the info! I will try that!
One question, however... Since I downloaded CodeLite with wxwidgets and it all worked out of the box... I am afraid that recompiling could damage what is already working...?

I will inform you on my progress...

Thank you again!

Well, setting up wxWidgets manually is a tiny bit more complicated than using a pre-compiled binary, that's right. But CodeLite comes with its own DLLs so you can't mess up CodeLite itself. You will need to reconfigure your project however.

Maybe you can ask the CodeLite author if he could provide builds with OpenGL included ;)
Or maybe you can use the binaries from wxPack. Or wx 2.9, since 2.9.x includes OpenGL by default

I have successfully recompiled wxWidgets with setup.h modified (hope it was the right one since more of them existed there; C:\wxWidgets-2.8.11\include\wx\msw\setup.h) and with command added USE_OPENGL=1 (and with RELEASE=debug instead of release)

Afterwards in CodeLite I have changed build environment form version 2.8.10 to 2.8.11 (one I recompiled) and run it...

It obviously complained about missing GL/glut.h which does not exist...
So I have downloaded precompiled GLUT libraries for Windows...
This time error compiling error was:

which (alongside the date in accompanying txt file that states year 2001) should mean that I have outdated version? Or build with different compiler?

Is my solution to download new version of GLUT and recompile it my computer???
Or, would it be more easier to use version 2.9 of wxWidgets???
Isn't that unstable release by the way?

Thank you for your help... I think we are making progress!

You need to link against the OpenGL DLL (and also the GLUT one, if you wish to use GLUT, but you could just remove the glut parts too)

FYI:
The wxWidgets that comes with codelite is not compiled with OpenGL

Hello!

- I have downloaded wxWidgets version 2.9.0
- then I have changed all setup.h which contained line wxUSE_GLCANVAS to "1"
- then I successfully recompiled with mingw but with options USE_OPENGL=1 and with BUILD=debug
- compiling penguin, cube and previous examples resulted in error messages like this (glut related lines were removed where they caused problems):

I will try now with "release" instead of "debug" since this is only thing that I modified...

You need to link against the OpenGL DLL. GO in your build settings and add the OpenGL DLL in the librairies over there

Hm...
No luck here... from what I found on Internet I should be linking against libopengl32.a (MinGW opengl library) since openGL.lib (not DLL) is from (for) Visual Studio...

in MinGW there is a tool called dlltool and something sounds like like reimp. With the latter you generate .def from dll and using that def file and dll you invoke dlltool to get .a file. I will post example for you later
