[BUG] Compilation problem on OS X

[brucey]

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

Hi,
Is this when being compiled with Xcode? Which version of the development tools is in use? Which SDK version is this being built against?

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
