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
