[BUG] Compilation problem on OS X

Postby brucey » Sat Dec 12, 2009 5:33 pm

In CEGUIOpenGLApplePBTextureTarget.cpp, I get two compilation problems related to an "invalid conversion ‘long int*’ to ‘GLint*’", on calls to CGLGetVirtualScreen() and CGLChoosePixelFormat().
I just added a cast to (GLInt*) and it compiled fine.
eg.
Code: Select all
    if (err = CGLGetVirtualScreen(cctx, (GLint*)&d_screen))

and
Code: Select all
    if (err = CGLChoosePixelFormat(fmtAttrs, &pix_fmt, (GLint*)&fmt_count))

Hi,

Thanks for this. Just a couple of questions to clarify a little... Is this when being compiled with Xcode? Which version of the development tools is in use? Which SDK version is this being built against?

I really only ask because Mac OS X is one of the platforms I use the most these days and I don't see these issues myself, so would like to try and identify where they are coming from without needing to test a dozen different configurations :)

CE.

It's being compiled with g++ using a custom make system, but it is using the XCode compile tools.
Building against the latest source from SVN trunk. But this error has occurred since that Mac-specific file was introduced.

The following is some output from the build, which gives an idea of the options being used, etc :
Code: Select all

Not such a big deal, as I just hack the code and move on, usually ;-)

Thanks for the info :) Looking at it, I'd guess it's a difference from the 10.3 SDK (since I only compile against 10.4 normally, this would explain why I do not see the issue). I'll look into it regardless and fix it - to save you a hack in future ;)
