#598: MacOS X / OpenGL and Wxpython incompatible ---------------------+------------------------------------------------------ Reporter: vince | Owner: [email protected] Type: defect | Status: new Priority: normal | Milestone: 6.4.0 Component: NVIZ | Version: svn-trunk Resolution: | Keywords: Platform: MacOSX | Cpu: OSX/Intel ---------------------+------------------------------------------------------ Comment (by vince):
Replying to [comment:5 hamish]: > dumb question: are 64bit binaries even needed for programs which will not load datasets of massive size? or is just 64bit and twice the memory to allocate and move around because 64>32 is somehow interpreted as "more must be better"? Definitely not. 64-bit, in Intel architectures, is better because all the math instructions will be executed by the SSE2 unit which is far more accurate and stable than the old i387. Then you have a lot of instructions that are simply not available in 32-bit mode, if not the 4 Gb barrier break. Finally, I think we must face it: 64-bit is the future, and MacOS 10.6 will be 64-bit from top to down, so better get prepared for it right now. > ie is there any real rush or advantage to have 64bit GUI components? None whatsoever. I've already patched configure to strip out -arch x86_64 and -arch ppc64 when checking for Tcl, so now configure runs okay. Next step is to remove those flags from Makefiles where we link against tk. Can someone tell me if this happen outside of GUI functions? -- Ticket URL: <http://trac.osgeo.org/grass/ticket/598#comment:6> GRASS GIS <http://grass.osgeo.org>
