如何从命令行启用'std = c ++ 0x'？

Question

我试图在离散分布后生成随机数并找到此链接：

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

我编译了他们给出的例子并得到了这个错误

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()':

这告诉我需要启用＆＃39; -std = c ++ 0x＆＃39;。这可以在IDE中轻松完成，但我如何通过cmd完成此操作？

像这样：

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

对于它的价值，你的编译器已经过时了。你最好更新到现代版本。
