From 43c991969ec5989ec093c07b487eb8fea2854be0 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Thu, 17 Apr 2014 22:23:32 -0700 Subject: [PATCH] Fixed bug 2489 - SDL2.framework references __Block_copy in /usr/lib/libSystem.B.dylib, but this symbol cannot be found on OSX-10.5 Thomas Schatz The dynamic library (extracted from SDL2-2.0.3.dmg and put in /Library/Frameworks/) references the __Block_copy symbol in /usr/lib/libSystem.B.dylib, which cannot be found: dlopen(/Library/Frameworks/SDL2.framework/SDL2, 6): Symbol not found: __Block_copy Referenced from: /Library/Frameworks/SDL2.framework/SDL2 Expected in: /usr/lib/libSystem.B.dylib From what I could gather __Block_copy seems to be related to the blocks extension to the C programming language introduced by Apple since OSX-10.6 (see: http://thirdcog.eu/pwcblocks/). If this is indeed the case, I don't think the SDL2-2.0.3.dmg on the website is at all compatible with OSX-10.5 countrary to what is announced. --- Xcode/SDL/SDL.xcodeproj/project.pbxproj | 2 ++ 1 file changed, 2 insertions(+) diff --git a/Xcode/SDL/SDL.xcodeproj/project.pbxproj b/Xcode/SDL/SDL.xcodeproj/project.pbxproj index 617975242..bd4be8ed3 100755 --- a/Xcode/SDL/SDL.xcodeproj/project.pbxproj +++ b/Xcode/SDL/SDL.xcodeproj/project.pbxproj @@ -2773,6 +2773,7 @@ 00CFA622106A567900758660 /* Release */ = { isa = XCBuildConfiguration; buildSettings = { + CLANG_LINK_OBJC_RUNTIME = NO; DYLIB_COMPATIBILITY_VERSION = 1.0.0; DYLIB_CURRENT_VERSION = 3.1.0; FRAMEWORK_VERSION = A; @@ -2827,6 +2828,7 @@ 00CFA628106A568900758660 /* Debug */ = { isa = XCBuildConfiguration; buildSettings = { + CLANG_LINK_OBJC_RUNTIME = NO; DYLIB_COMPATIBILITY_VERSION = 1.0.0; DYLIB_CURRENT_VERSION = 3.1.0; FRAMEWORK_VERSION = A;
