Compiling

You need a C++20 compatible compiler such as GCC 10.2.0 to compile ImHex. Moreover, the following dependencies are needed for compiling ImHex:

• GLFW3
• libmagic, libgnurx, libtre, libintl, libiconv
• libcrypto
• capstone
• nlohmann json
• Python3
• freetype2
• Brew (macOS only)

Windows and Linux

Find all-in-one dependency installation scripts for Arch Linux, Fedora, Debian/Ubuntu and/or MSYS2 in dist.

After all the dependencies are installed, run the following commands to build ImHex:

mkdir build
cd build
cmake ..
make -j

---

To create a standalone zipfile on Windows, get the Python standard library (e.g. 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

macOS

To build ImHex on macOS, run the following commands:

brew bundle --no-lock --file dist/Brewfile
mkdir build
cd build
CC=$(brew --prefix llvm)/bin/clang CXX=$(brew --prefix llvm)/bin/clang++ PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig":"$(brew --prefix)/lib/pkgconfig" cmake ..
make -j
