【问题描述】：

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 控制台打印这样的消息：

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

gdb 连续打印这些消息，因此我无法调试我的程序。

我确定我没有设置 DYLD_FRAMEWORK_PATH。也许 xcode4 或 cmake 可以在某处设置/取消设置此环境变量？

我已经尝试过像这个答案一样重置 DYLD_FRAMEWORK_PATH，但不起作用 How do I set up environment variables for my product in Xcode 4?

谢谢

【解决方案1】：

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标题/框架/库搜索路径并点击递归复选框，它将递归添加每个子路径。这可能是大量路径（字符串太长而无法放入 env var）。这给我带来了类似的问题。

在这种情况下，我真正想做的只是添加一个搜索路径，用于查找主标题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。
