How do I invoke the MinGW cross-compiler on Linux?

by

If you look at the file lists on the Ubuntu package webserver for mingw-w64‘s constituent packages:

  • gcc-mingw-w64-x86-64
  • g++-mingw-w64-x86-64
  • binutils-mingw-w64-x86-64
  • mingw-w64-x86-64-dev
  • gcc-mingw-w64-i686
  • g++-mingw-w64-i686
  • binutils-mingw-w64-i686
  • mingw-w64-i686-dev

You can see that mingw-w64 provides a toolchain, i.e. a set of alternative tools (compiler, linker, headers, etc.) used to compile your code for another system.

Assuming you want to compile C++ code for a 64-bit system, you’ll need to use /usr/bin/x86_64-w64-mingw32-g++-win32. You can use the CXX environment variable to tell most Makefiles to use that compiler to compile code.
