Based on Jones Forth. The number of natively defined words is kept very low on purpose to ease porting.
A C compiler (GCC and MSVC tested) is needed to build the C version.
The x86/x64 assembly versions require NASM.
It's easiest to build using CMake. In the source directory run:
mkdir build
cd build
cmake ..
cmake --build .
To cross-compile for ARM (for debian install gcc-arm-linux-gnueabihf
and libc6-dev-armhf-cross):
cmake -DCMAKE_TOOLCHAIN_FILE:PATH=../toolchain-arm.cmake ..
The interpreter(s) read from standard input by default, but a filename can be supplied on the command line.
