如何启用Codelite中的C ++ 11功能 [英] How to Enable C++11 Features in Codelite
问题描述
以下代码在Xcode 5和Visual Studio 2013中编译和运行。我有兴趣尝试Codelite，但Codelite不会编译以下程序（一个问题，因为我在我的项目中使用scoped枚举）。根据我的理解，Codelite使用与Xcode相同的编译器。
The following code compiles and runs in Xcode 5 and in Visual Studio 2013. I am interested in trying out Codelite, but Codelite will not compile the following program (a problem since I am working with scoped enums in my project). As far as I understand it, Codelite is using the same compiler as Xcode.
每个C ++ 11的代码是否有效？为什么Codelite无法编译它？
Is the code valid per C++11? Why is Codelite unable to compile it?
#include <iostream>
namespace abc
{
namespace xyz
{
enum class SampleEnum
{
SomeValue = 0,
SomeOtherValue = 1
};
}
}
int main(int argc, char **argv)
{
abc::xyz::SampleEnum e = abc::xyz::SampleEnum::SomeValue;
return 0;
}
这是Codelite的构建输出。如果它是乱码，它在变量的实例化和说期望一个类或命名空间指向单词SampleEnum。
Here is the build output from Codelite. In case it's garbled, it's pointing to the word "SampleEnum" in the instantiation of the variable and saying "expected a class or namespace".
/bin/sh -c 'make -j8 -e -f Makefile'

codelite-cc /usr/bin/clang++ -c "/Users/xxx/Desktop/Test/ClangTest/main.cpp" -g -O0 -Wall -o ./Debug/main.cpp.o -I. -I.

推荐答案
有必要将-std = c ++ 11传递给编译器以启用C ++ 11功能。下面是在Codelite中执行此操作的步骤：
It is necessary to pass -std=c++11 to the compiler to enable C++11 features. Here are the steps to do so in Codelite:
- 在工作区视图中右键单击项目。
- 选择此弹出式菜单底部附近的设置。通用设置 - >编译器 - > C ++编译器选项
- 单击分号分隔的编译器开关列表以显示缺省值并单击缺省值。
- 点击-std = c ++ 11的复选框。
- Right click on the project in the workspace view.
- Select Settings near the bottom of this pop-up menu. Common Settings->Compiler->C++ Compiler Options
- Click into the semicolon delimited list of compiler switches to reveal elipses and click on the elipses.
- Click the checkbox for -std=c++11
