Question

自从将Xcode更新为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 ldap [system] [extern_c] {
                      ^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/module.map:1635:23: warning: unknown attribute 'extern_c' [-Wignored-attributes]
module krb5 [system] [extern_c] {
                      ^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/module.map:1662:22: warning: unknown attribute 'extern_c' [-Wignored-attributes]
module XPC [system] [extern_c] {
                     ^

除了忽略-Wignored-attributes之外，有没有人知道如何解决这个问题？

原来我使用旧版本的clang和Xcode的SDK。使用默认的clang摆脱了警告。

如何摆脱OSX10.10 SDK中的module.map警告？
