Re: [osg-users] OSG on iPhone (size?)
Hi All I've been spending the last few hours trying to save some extra KB off of my final exe size onIOS. In the end I got my final exe from nearly 10 MB down to 3.T MB, sweet ay I'm using OpenThreads, osg, osgUtil, osgGA, osgViewer, osgDB, depreciated osg pugin and imageio plugin. The trick has been firstly build the osg libs with Optimization set to Fastest-Smallest. Then I set my exe to build for ARM 7 only, this way you basically half the exe size. Bear in mind though that ARM 7 chips are only in 3GS and above One other tip is to only draw in the parts of the plugins you need e.g. I load Texture2D from files, but i don't tend to load Texture1D //USE_DOTOSGWRAPPER(Texture1D) USE_DOTOSGWRAPPER(Texture2D) Cheers Thomas -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38662#38662 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, Am 02.12.10 03:54, schrieb Chris 'Xenon' Hanson: I don't know if you can static link on iOS, or how you would go about doing it. For now static linking is the only way on IOS. So the lib sizes do not matter, as only needed code get linked into the app. And: most of the time I am only using OpenThreads, osg, osgDB, osgGA, osgUtil and osgViewer, you don't have to include all libs. One of my osg based iphone apps is about 20 MB which utilize some of the osg libs, and some of my own libs. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] OSG on iPhone (size?)
Hello Mike: I have not tried to build the iphone OS port but it appears in your cut and paste you have the Active configuration as Debug as seen with the link path .Debug-iphoneos/osg.build/osg-generated-files.hmap. What are the Active configuration targets available and if a Release target is available try to select that. There should be a drop down box labeled Active Build Configuration or an equivalent. There just appears to be some level of debug symbols still in your binary distribution.

Okay... so the libraries need to have all of that (ie, all symbols), but when the .app is created and dead code stripping is enabled, any unneeded symbols are stripped away.
