I have two gcc's installed in cygwin right now: i686-w64-mingw32-gcc-4.5.3.exe and the cygwin gcc. Ill show you what I did for the sake of clarity:
我现在有两个gcc安装在cygwin中:i686-w64-mingw32-gcc-4.5.3。exe和cygwin gcc。我会给你看我为了清楚起见做了什么:
$ ls -al /usr/bin/gcc* lrwxrwxrwx 1 User None 21 Aug 16 13:15 /usr/bin/gcc.exe -> /etc/alternatives/gcc -rwxr-xr-x 2 User None 94741 Feb 25 2009 /usr/bin/gcc-3.exe $ ls -al /etc/alternatives/gcc* lrwxrwxrwx 1 User None 18 Aug 16 13:15 /etc/alternatives/gcc -> /usr/bin/gcc-3.exe $ rm /etc/alternatives/gcc $ ln -S /usr/bin/i686-w64-mingw32-gcc-4.5.3.exe /etc/alternatives/gcc $ gcc -v Using built-in specs.

How do I get gcc to work?

If you need a native MinGW-w64 GCC, use a native Windows version of the compiler and call it from cmd or if you must MSYS. If not, use the Cygwin to Windows cross-compiler and encode the prefix in a Makefile/CMakeLists.txt/configure script.
如果您需要一个本地的MinGW-w64 GCC，请使用编译器的本地Windows版本，并从cmd调用它，或者您必须使用MSYS。如果没有，请将Cygwin应用于Windows交叉编译器，并在Makefile/CMakeLists中对前缀进行编码。txt / configure脚本。
Remember Cygwin != Windows, and what you are doing is cross-compiling, which in GCC land is done by calling prefixed binaries.
记住Cygwin != Windows，你所做的是交叉编译，在GCC中，通过调用前缀二进制文件来完成。

I think you need to change the gcc symlink in /usr/bin to point to your correct version of GCC. Alternatively, you can edit your PATH to have /etc/alternatives come before /usr/bin, but that may have unintended side effects, depending on your setup.
我认为您需要更改/usr/bin中的gcc symlink来指向正确版本的gcc。或者，您可以编辑您的路径以在/usr/bin之前使用/etc/替代品，但这可能会产生意外的副作用，这取决于您的设置。
