programming type: I took a Juce tutorial and am moving from just getting Juce and Codeblocks to not ignore each other to audio programming and knowing nothing about a few more things. I bought this synth editor named Flowstone that works with Ruby code but I don't know Ruby yet either.. not well enough to customize that thing yet.
Click on start.bat, not on nim.exe and run something like cd path_to_hello_nim and then nim c -r myhello.nim. You don't need PCRE or SSL, Nim ships with them. You don't need to install MingGW, finish.exe does that for you, you need to let finish.exe write the PATH. And by now your computer setup is probably so messed up that nothing works, read about the basics of your operating system, presumably Windows:
