【问题描述】：
我尝试按照 README.md 中的说明从源代码编译最新的平铺。
我的工作环境：
平铺源代码：平铺-0.16.1
Mac 操作系统：10.11.1
Xcode：7.1
QMake：3.0
Qt：5.7.0
苹果 LLVM：7.0.0
但是 make 失败并出现以下错误：

经过一番研究，我尝试在tiled.pro 文件中添加一行CONFIG+= c++11，然后make clean、qmake、make，但我仍然遇到同样的错误......
平铺.pro：
# Check the Qt version. If QT_VERSION is not set, it is probably Qt 3.
isEmpty(QT_VERSION) {
error("QT_VERSION not defined. Tiled does not work with Qt 3.")
}
include(tiled.pri)
!minQtVersion(5, 1, 0) {
message("Cannot build Tiled with Qt version $${QT_VERSION}")
error("Use at least Qt 5.1.0.")
}
TEMPLATE = subdirs
CONFIG += ordered
CONFIG += c++11
SUBDIRS = src translations
不知道这里出了什么问题。
任何建议将不胜感激，谢谢:)
更新：
试过了
QMAKE_CXXFLAGS += -std=c++11
和
QMAKE_CXXFLAGS += -std=c++0x
还是一样的错误......
我想可能是在C++编译make命令使用，这里是一些资料：

【问题讨论】：
-
也试试
QMAKE_CXXFLAGS += -std=c++11 -
也可以试试
QMAKE_CXXFLAGS += -std=c++0x -
感谢您的快速回答尝试了两个标志，但仍然有相同的错误。请查看此问题的更新信息。

你试过编译其他项目吗？如果没有，您可能需要打开 Xcode 并接受其许可协议或在终端中运行它：
xcode-select --install
