### These instructions are a WIP and may be missing steps

## Compiling mk64 Decomp In Windows
|
||||
|
||||
The extraneous and convoluted process to building mk64 decomp on Windows begins with disabling your anti-virus program or adding an exception to the mk64 decomp folder and/or the msys2 installation folder.

### Preamble
|
||||
Any misteps may require a complete uninstall of `MSYS2 MinGW x64` and restarting from the very beginning.
|
||||
It is unknown if `MSYS MinGW x32` works.

It is unknown if `MSYS MinGW x32` is supported (most likely not).

Follow the initial instructions to update the base packages. Ignore installing any extra packages in-case they conflict with the below steps.
|

|
||||
MinGW is a separate program from Msys2. However, it must be wrapped right into msys2.
|
||||
Compiling recomp requires steps using `MSYS2 MSYS` *and* `MSYS2 MinGW x64`. The instructions will clearly differentiate which program to launch and run in the section titles.

##### Why flip-flop between both?
|
||||
Compiling the recomp executable that generates the source files for compiling the compiler requires capstone. A disassembly, analysis, and reverse-engineering framework. Capstone is only available on `MSYS2 MinGW x64`. It is not available on `MSYS2 MSYS`. However, compiling the compiler itself requires `MSYS2 MSYS` because it contains an equivallent dependency for `mman`. A memory mapping library. `MSYS2 MinGW x64` does not contain an equivallent dependancy.
