问题
I want to use Regular expression in c++11 and gcc 4.8.2 supports it. But the MinGW installer only supports up to gcc 4.8.1. How can I update it to gcc 4.8.2?
回答1:
You can manually install it yourself. There's a MinGW-w64 distribution for 4.8.2 available here.
You'll need 7zip to extract the file contents. After you unzip it to a location of you're choosing just add the bin subdirectory from there to your environment path and you should be good to go.
For example, if you extracted the toolchain into x:\mingw32-4.8.2 then add x:\mingw32-4.8.2\bin using
setx path "%path%;x:\mingw32-4.8.2\bin"
Restart the Command Prompt for it to take effect. If you have an older mingw version installed you might want to remove that to avoid potential conflicts.
