Re: Yet Another Plotting System for Octave

[Marius Schamschula]

Alex,

I looked around a bit more (otool -L = ldd on Linux):

Saturn:~ marius$ otool -L /usr/X11R6/lib/libGL.dylib              

/usr/X11R6/lib/libGL.dylib:

        /usr/X11R6/lib/libGL.1.dylib (compatibility version 1.2.0, current version 1.2.0)

        /usr/lib/libXplugin.1.dylib (compatibility version 1.0.0, current version 1.0.0)

        /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib (compatibility version 1.0.0, current version 1.0.0)

        /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices (compatibility version 1.0.0, current version 22.0.0)

        /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 368.27.0)

        /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)

        /usr/X11R6/lib/libXext.6.dylib (compatibility version 6.4.0, current version 6.4.0)

        /usr/X11R6/lib/libX11.6.dylib (compatibility version 6.2.0, current version 6.2.0)

        /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.4)

Saturn:~ marius$ nm /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib | grep glBegin

92e83a4c T _glBegin

92e92b38 T _glBeginQuery

92e9b2f8 T _glBeginQueryARB

so glBegin is in the OpenGL.Framework...

Oops,

I was a bit quick to say that yapso installed correctly:

The install died with

checking for glBegin in -lGL... no

but

Saturn:~ marius$ nm /usr/X11R6/lib/libGL.dylib | grep glBegin

00002d7c T ___indirect_glBegin

         U _glBegin

         U ___indirect_glBegin

         U ___indirect_glBegin

Any ideas?

From the man page of nm, "U _glBegin" means that _glBegin is used but not defined in this library

since we don't see a "T _glBegin".

On my linux system (Fedora 5), I get:

nm libGL.a | grep glBegin

                 U glBegin

                 U glBeginFragmentShaderATI

                 U glBeginQueryARB

00000000000000b0 T glBegin

0000000000006c90 T glBeginFragmentShaderATI

0000000000004dc0 T glBeginQuery

0000000000004dc0 T glBeginQueryARB

I guess, that glBegin is defined in another (lower level) library. Can you run the following command?

nm --print-file-name *.dylib | grep glBegin

Cheers,

Alex

Marius
