Users looking for such functionality should look to Cygwin or Microsoft&#039;s Interix instead.<br /> To build an application for MSYS (as opposed to using MSYS), users will need to install the MSYS Toolchain. It contains headers and libraries for MSYS along with a patched version of GCC and Binutils.<br /> An example would be building a library that uses the autotools build system. Users will typically run &quot;./configure&quot; then &quot;make&quot; to build it. The configure shell script requires a shell script interpreter which is not present on Windows systems, but provided by MSYS.";
