## Compiling

This guide assumes you're either on Windows using mingw or on Arch Linux

The following libraries are needed to compile ImHex. All of them can be found in the default pacman repositories
```
GLFW3                                             ( (sudo) pacman -S glfw )
libmagic, libgnurx, libtre, libintl, libiconv     ( (sudo) pacman -S file )
libcrypto                                         ( (sudo) pacman -S openssl )
capstone                                          ( (sudo) pacman -S capstone )
libLLVMDemangle                                   ( (sudo) pacman -S llvm llvm-libs )
nlohmann json                                     ( (sudo) pacman -S nlohmann-json )
Python3                                           ( (sudo) pacman -S python3 )

All in one: sudo pacman -S glfw file openssl capstone llvm llvm-libs nlohmann-json python3
```

After all the libraries are installed, run the following commands to build ImHex
```
mkdir build
cd build
cmake ..
make -j
```

On Windows, download the python standard library from https://github.com/python/cpython/tree/master/Lib and place the files and folders in `lib/python3.8` next to your built executable. Don't forget to also copy the `libpython3.8.dll` and `libwinpthread-1.dll` from your mingw setup next to the executable.

On both Windows and Linux, copy the files from `python_libs` in the `lib` folder next to your built executable.
Place your magic databases in the `magic` folder next to your built executable
Place your patterns in the `pattern` folder next to your built executable
Place your include pattern files in the `include` folder next to your built executable
