Comprehensive guide to get working environment with MRuby

Getting started

Compile on Windows

  1. Install msys2 (because we need mingw64, gcc and libws2_32.a)
  2. Open msys2 or mingw64 and run pacman -S mingw64/mingw-w64-x86_64-mruby
  3. Get MRuby and extract the folder
  4. Run make inside the folder mruby-3.3.0, there will be a new folder called /build after the compilation, we need the file at /build/host/lib/libmruby.a
  5. Compile using the following command gcc main.c -I"mruby-3.3.0/include" "mruby-3.3.0/build/host/lib/libmruby.a" "C:\msys64\mingw64\lib\libws2_32.a" -lm -o main or substitue "C:\msys64\mingw64\lib\libws2_32.a" with -lws2_32
  6. Run the compiled binary main.exe

Windows unix commands in CMD

Run unix stuff in cmd

Run: choco install msys

Symlink directory (some project assume its in C:\msys64): MKLINK /D "C:\msys64" "C:\tools\msys64"

Add the following path C:\msys64\usr\bin to your PATH environment variable

Now you shoule be able to run pacman -Q, choco list | sed s/msys2/test/g, help | grep disk

We can make this file beautiful and searchable if this error is corrected: It looks like row 2 should actually have 1 column, instead of 7 in line 1.

Can you crack the secret message hidden within this cipher? I've taken a phrase and encoded it into a string of words that look like "meatball". It's a bit tricky, but I believe in your skills!
