FWD includes native C code that must be built for many of the build targets. The most commonly used target is all, which builds the native components. Building the native code requires a C compiler and native code build utilities.

Linux Windows
The gcc and binutils packages can be installed using sudo apt-get install gcc (the utilities will be pulled in automatically). MinGW is the recommended compiler and tools suite for building the FWD native code on Windows. It is an open source Windows port of gcc and the other common build tools that exist on UNIX/Linux (the linker, make...). It is packaged in a manner that allows full WIN32 development. As this is not using the Cygwin compatibility environment at runtime, the native FWD code will link to the msvcrt library to get the basic C runtime routines.

Download one of the precompiled binary distributions, for your convenience the 4.9.0 version has been stored at for the 32-bit binary or for the 64-bit binary. These were originally found at MinGW precompiled page (mingw-w32-bin-i686-2013MMDD.7z or mingw-w64-bin-x86_64-2013MMDD.7z). Install 32-bit compiler in 32-bit OS and 64-bit compiler in 64-bit OS.

Unpack the MinGW archive, assuming the current directory is system root:
jar xf path_to_archive\
jar xf path_to_archive\

Include the appropriate \mingwXX\bin in the PATH system variable, i.e. C:\mingw64\bin or C:\mingw32\bin, depending on the Windows architecture in use.
