OK, I've got a working libGL.dylib now, and glut compiles/links through, as do all the other macports programs I tried.

Still, I'm not really where as I want to be w/ my leopard system, because of two different issues

a) manta-independent:
Macports seem to still build in 32-bit mode, at least the libglut.dylib contains only a 32-bit i386 version, whereas libGL.dylib contains both G5 versions, intel 32-bit, and intel 64-bit versions.
The same is true for all macports modules I build, including, e.g., libmagick.dylib, etc.
Does anybody know of a way how I can tell macports to build in 64 bit mode ?

b) manta specific:
I can't even compile through, it dies in a weird position:

/Users/ingowald/Projects/manta/SCIRun/Core/Thread/Thread_pthreads.cc(736): error: incomplete type is not allowed
 handle_quit(int sig, SigContext /*ctx*/)

The problem is that line 736 should only be compiled if CYGWIN is defined, which (I think) shouldn't happen under leopard, should it ?

I havent seen this particular problem , it's likely an issue between the old x11 that shipped with OSX and the new--but in general I would link to the Apple version of GLUT instead of the Darwin port version.

You also probably don't need to run glut applications through the X11 server.. (also glut isnt a manta dependency).

Hi all,

I just tried building manta on my leopard-updated machine, and since it didn't work, I started to suspect macports to not be properly updated (it still had everything 32-bit).

To track it down, I eventually uninstalled all of macports, made sure I have the newest xcode installed, got the newest version of the macports installer, and installed it.

port selfupdate runs through, and says everything is up to date, but then, a simple "sudo port install glut" already runs into gl link errors:

Any ideas ?

PS: BTW - it seems to be somewhat related to two different libGL's with different contents
207:icc ingowald$ nm /Developer/SDKs/MacOSX10.5.sdk/usr/X11/lib/libGL.dylib | grep glPushMatrix
00007c55 T ___indirect_glPushMatrix
       U _glPushMatrix
207:icc ingowald$ nm /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib | grep glPushMatrix
00001370 T _glPushMatrix
...
but don't ask me why these files differ if they're both in the 10.5.sdk subdir, nor why there are multiple files at all, or why macports uses the wrong (?) one ....
