c++ - 如何从命令行启用 'std=c++0x'？

Question

我试图生成遵循离散分布的随机数并找到了这个链接:

http://www.cplusplus.com/reference/random/discrete_distribution/

我编译了他们给的例子，出现了这个错误

C:\Users\Anand\Desktop>g++ random.cpp -o rand
In file included from c:\mingw\bin\../lib/gcc/mingw32/4.6.2/include/c++/random:3
5:0,
             from random.cpp:3:
c:\mingw\bin\../lib/gcc/mingw32/4.6.2/include/c++/bits/c++0x_warning.h:32:2: err
or: #error This file requires compiler and library support for the upcoming ISO
C++ standard, C++0x. This support is currently experimental, and must be enabled
 with the -std=c++0x or -std=gnu++0x compiler options.
random.cpp: In function 'int main()':

这表明我需要启用“-std=c++0x”。这可以在 IDE 中轻松完成，但我如何通过 cmd 执行此操作？

像这样:

g++ -std=c++0x random.cpp -o random.exe

就其值(value)而言，您的编译器已经过时了。你最好更新到现代版本。
