Compile
Better download the latest update source of the interpreter and build it! It's quite easy to build this interpreter, what you need are only two things: C++ compiler and the make. There is no third-party library used in this project.
Make sure thread model is posix thread model, otherwise no thread library exists.
mingw32-make nasal.exe -j4
There is a CMakelists.txt to create project.
make -j
You could choose which compiler you want to use:
make nasal CXX=... -j
