导读：自从将 Xcode更新到6.3版以来,我在编译C代码时收到了以下警告： /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/module.map:1:25: warning: unknown attribute 'extern_c' [-Wignored-a

自从将 Xcode更新到6.3版以来,我在编译C代码时收到了以下警告：

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/module.map:1:25: warning: unknown attribute 'extern_c' [-Wignored-attributes]
module Darwin [system] [extern_c] {
                        ^

module os [system] [extern_c] {
                    ^

module krb5 [system] [extern_c] {
                      ^

module XPC [system] [extern_c] {
                     ^

除了忽略-Wignored属性之外,有没有人知道如何解决这个问题？

解决方法

事实证明我使用旧版本的clang和Xcode的SDK.使用默认的clang删除警告.
