C++ 无法在运行Apple LLVM 10.0.1版的mac上捕获2 hello测试

我只是在尝试我的教程来尝试catch2单元测试库。我用10.14的mac电脑。 我没有完整的XCode，只有cmd工具和macports在我的设置中运行完美（没有brew）。 我使用合并的单头文件和源文件的建议

然而，一个简单的教程：

#define CATCH_CONFIG_MAIN  // This tells Catch to provide a main() - only do this in one cpp file
#include "catch.hpp"

unsigned int Factorial( unsigned int number ) {
    return number <= 1 ? number : Factorial(number-1)*number;
}


TEST_CASE( "Factorials are computed", "[factorial]" ) {
    REQUIRE( Factorial(1) == 1 );
    REQUIRE( Factorial(2) == 2 );
    REQUIRE( Factorial(3) == 6 );
    REQUIRE( Factorial(10) == 3628800 );
}

请推荐，谢谢

@Tiib建议尝试使用

g++-std=c++17

后，代码被编译并生成

g++-std=c++11

也不起作用。不明白为什么。

您试图用什么命令编译代码？看来你在某些C++ 11模式下运行编译器，C++ 11确实改变了C++语法。只是做了<代码> GCC Test1.CPP。有没有其他方法来构建测试？试试gcc-std=c++11 test1.cpp输出都是一样的。嗯，但是clang++-std=c++11 test1.cpp
