C++錯誤：'內聯'只能出現在函數上

Question

我想在OS X 10.7下使用clang ++編譯VCMI。

我配置了CXX=clang++的項目，因爲蘋果的gcc似乎沒有認出所需的-std=c++0x標誌。

我添加了-stdlib=libc++到CXXFLAGS，因爲沒有那個鏗鏘聲甚至沒有找到#include <array>。

目前我已經有了：CXXFLAGS= -std=c++0x -stdlib=libc++ -Wall -Wextra -Wcast-align -Wpointer-arith -Wno-switch -Wno-sign-compare -Wno-unused-parameter -Wc++11-extensions

的問題是，我收到以下錯誤：

clang: warning: treating 'c-header' input as 'c++-header' when in C++ mode, this behavior is deprecated 
clang: warning: argument unused during compilation: '-ggdb'

我必須承認，我從來沒有見過這樣的事。這些都在libC++源代碼中！ 有人知道可能是什麼原因嗎？

你的問題就在這裏：

./../tchar_amigaos4.h:157:16: note: expanded from macro '_T' 
#define _T(x)   x 

定義一個名爲_T宏在你的代碼，然後包括標準的頭，是不確定的行爲，嚴格地說。

IIRC，較新版本的libC++避免使用名稱_T，特別是因爲人們傾向於這樣做，所以您可能想嘗試升級到最新版本的命令行工具。
