Xcode 4 中出现了“环境变量过长”的错误提示

Question

我有一个由cmake生成的Xcode 4项目。

当我在我的iOS设备（iPod/iPad）上构建并尝试调试时，

gdb控制台会打印出这样的消息：

warning: Environment variable too long, skipping: DYLD_FRAMEWORK_PATH=/Users/dokinkon/src/gamekit/build_iphone/Samples/IPhoneDemo/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/GameKit/Utils/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/GameKit/AnimKit/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/Blender25/Serialize/BlenderSerialize/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/Blender25/Serialize/BulletFileLoader/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/FreeImage/ZLib/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/FreeType/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/OIS/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/Codecs/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/Lua/lua/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Dependencies/Source/FreeImage/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Ogre-1.8/OgreMain/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/bullet/src/BulletDynamics/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/bullet/src/BulletCollision/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/bullet/src/LinearMath/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Ogre-1.8/RenderSystems/GLES/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Ogre-1.8/PlugIns/ParticleFX/bin-iphoneos/Release:/Users/dokinkon/src/gamekit/build_iphone/Engine/bin-iphoneos/Release

会连续打印这些信息，导致我无法调试程序。 <我确定我没有设置DYLD_FRAMEWORK_PATH。也许Xcode4或cmake在某个地方设置/取消设置了这个环境变量？

我已经尝试像这个答案一样重置DYLD_FRAMEWORK_PATH，但没有作用。 如何在Xcode 4中为我的产品设置环境变量？

谢谢

不确定这是否是您的问题，但如果您在目标的构建设置中设置了头文件/框架/库搜索路径并勾选了递归复选框，则会递归添加每个子路径。这可能会导致路径数量巨大（字符串太长而无法适合环境变量）。这曾经给我带来过类似的问题。

在那种情况下，我真正想做的是仅添加一个搜索路径，以便找到主头文件或特定框架或框架文件夹的位置。一旦我进行了调整，它就可以正常工作了。
