RGL again
One more thing. R 2.1.1 that comes from CRAN has libR statically linked against libpng, thus png support is there already (try png(); example(plot); dev.off()) But if you want to build rgl package you need to have libpng include files (at least). So you only need to install libpng following the steps at http:// www.economia.unimi.it/R and remove all *png*.dylib entries from /usr/ local/lib. stefano

I have upgraded to Tiger 10.4.2 and R 2.1.1. When launching rgl, everything seems to work OK. However the demo(rgl) doesn't do what it is supposed to do. demo(hist3d) works perfectly, but demo(abundance) just produces a single sphere. demo(regression) doesn't draw the points, demo (lsystem) displays the error message RGL: Pixmap load: file format unsupported RGL: Pixmap load: failed and in demo(bivar) once you click and try to move the surface on the X11 graphics window it disappears. Any similar behaviour from any of you? Any hints?
You are doing better than me. My attempt to install rgl from source ends thus: g++ -no-cpp-precomp -I/Library/Frameworks/R.framework/Resources/ include -I/System/Library/Frameworks/OpenGL.framework/Headers -I/ usr/ X11R6/include -DDarwin -DNO_GL_PREFIX -I/usr/X11R6/include -I/usr/ local/include -Wall -pedantic -fno-exceptions -fno-rtti -fno-common -g -O2 -c scene.cpp -o scene.o types.h:76: warning: 'class DestroyHandler' has virtual functions but non-virtual destructor gui.h:55: warning: 'class gui::WindowImpl' has virtual functions but non-virtual destructor gui.h:89: warning: 'class gui::GUIFactory' has virtual functions but non-virtual destructor pixmap.h:39: warning: 'class PixmapFormat' has virtual functions but non-virtual destructor scene.cpp: In member function 'void Texture::beginUse (RenderContext*)': scene.cpp:1994: error: invalid conversion from 'int*' to 'GLint*' make: *** [scene.o] Error 1 which looks pretty terminal. I fudged up the code in scene.cpp and got it to install. Now I have your problem. I assume this is because the R binary has been built without libpng. Mine certainly was. I will try again with libpng. Bill Northcott PS Rebuilt R with libpng and now it all works.
