@H_403_1@我正在尝试打开一个使用iOS 6.0构建的旧项目.该项目用于编译正常,但在xCode 5下打开时,我得到这个神秘的错误消息.
Unsupported compiler 'com.apple.compilers.llvmgcc42' selected for architecture 'armv7' Unable to determine concrete GCC compiler for file /Users/alexanderstone/Desktop/Development/RestKit/Vendor/NXJSON/NSError+Extensions.m of type sourcecode.c.objc.

Unable to determine concrete GCC compiler for file /Users/alexanderstone/Desktop/Development/RestKit/Vendor/NXJSON/NXJsonSerializer.m of type sourcecode.c.objc.
我已经检查了两个项目构建设置,它们看起来是正确的 – LLVM 5.0被选为两者的编译器.
另外,我检查了编译器抱怨的.m文件,并且没有看到任何对GCC的引用.有一些ASSERT()和其他宏,但我不知道它们是否是特定于编译器的.
当所有子项目似乎都设置为llvm5.0时,如何解决xCode 5中缺少的llvmgcc4.2编译器？
解决方法
Found this similar question.对我来说,解决方案是转到编辑器>验证子项和Restkit项目的项目设置.
