This is the biggest "visibility" patch. Instead of doing a "export" symbol on demand, export everything in the sdk, so that if some module fails due to an unresolved symbol, it is because it is using a symbol not in the sdk. Most exported symbols shouldn't really be made visible, neither advertised in the sdk, as they are only used by a single shared object. Symbols in the sdk (or referenced in sdk macros), but not defined anywhere include: XkbBuildCoreState() XkbInitialMap XkbXIUnsupported XkbCheckActionVMods() XkbSendCompatNotify() XkbDDXFakePointerButton() XkbDDXApplyConfig() _XkbStrCaseCmp() _XkbErrMessages[] _XkbErrCode _XkbErrLocation _XkbErrData XkbAccessXDetailText() XkbNKNDetailMaskText() XkbLookupGroupAndLevel() XkbInitAtoms() XkbGetOrderedDrawables() XkbFreeOrderedDrawables() XkbConvertXkbComponents() XkbWriteXKBSemantics() XkbWriteXKBLayout() XkbWriteXKBKeymap() XkbWriteXKBFile() XkbWriteCFile() XkbWriteXKMFile() XkbWriteToServer() XkbMergeFile() XkmFindTOCEntry() XkmReadFileSection() XkmReadFileSectionName() InitExtInput() xf86CheckButton() xf86SwitchCoreDevice() RamDacSetGamma() RamDacRestoreDACValues() xf86Bpp xf86ConfigPix24 xf86MouseCflags[] xf86SupportedMouseTypes[] xf86NumMouseTypes xf86ChangeBusIndex() xf86EntityEnter() xf86EntityLeave() xf86WrapperInit() xf86RingBell() xf86findOptionBoolean() xf86debugListOptions() LoadSubModuleLocal() LoaderSymbolLocal() getInt10Rec() xf86CurrentScreen xf86ReallocatePciResources() xf86NewSerialNumber() xf86RandRSetInitialMode() fbCompositeSolidMask_nx1xn fbCompositeSolidMask_nx8888x0565C fbCompositeSolidMask_nx8888x8888C fbCompositeSolidMask_nx8x0565 fbCompositeSolidMask_nx8x0888 fbCompositeSolidMask_nx8x8888 fbCompositeSrc_0565x0565 fbCompositeSrc_8888x0565 fbCompositeSrc_8888x0888 fbCompositeSrc_8888x8888 fbCompositeSrcAdd_1000x1000 fbCompositeSrcAdd_8000x8000 fbCompositeSrcAdd_8888x8888 fbGeneration fbIn fbOver fbOver24 fbOverlayGeneration fbRasterizeEdges fbRestoreAreas fbSaveAreas composeFunctions VBEBuildVbeModeList() VBECalcVbeModeIndex() TIramdac3030CalculateMNPForClock() shadowBufPtr shadowFindBuf() miRRGetScreenInfo() RRSetScreenConfig() RRModePruneUnused() PixmanImageFromPicture() extern int miPointerGetMotionEvents() miClipPicture() miRasterizeTriangle() fbPush1toN() fbInitializeBackingStore() ddxBeforeReset() SetupSprite() InitSprite() DGADeliverEvent() SPECIAL CASES o defined as _X_INTERNAL xf86NewInputDevice() o defined as static fbGCPrivateKey fbOverlayScreenPrivateKey fbScreenPrivateKey fbWinPrivateKey o defined in libXfont.so, but declared in xorg/dixfont.h GetGlyphs() QueryGlyphExtents() QueryTextExtents() ParseGlyphCachingMode() InitGlyphCaching() SetGlyphCachingMode()
