• PHP (optional, for preprocessing of gfx2imgui.lua)

(* The C++ compiler must be ABI-compatible with MSVC on Windows)

Library requirements:

By default these will be picked up from the system or downloaded if missing.

• Boost (1.81 or newer)
• fmt (only if C++20 is not available)
• FreeType
• GoogleTest
• libjpeg-turbo
• libpng
• md4c
• zlib

Additional system dependencies on Linux:

• Fontconfig
• GDK3 (3.22 or newer)

Fetch the repository including submodules:

$ git clone --recursive --shallow-submodules https://github.com/cfillion/reaimgui.git 

Build ReaImGui using Meson:

$ meson setup build $ cd build $ ninja 

The change the installation directory to a portable install:

$ meson configure -Dresource_path=~/path/to/your/portable/install/ 

Downgrade to C++17 if compiling on macOS with Xcode older than 14:

$ meson configure -Dcpp_std=c++17 

Run the test suite using:

$ meson test 

Install ReaImGui into your REAPER resource path using:

$ meson install --tags runtime 

QEMU is used to run compiled binaries for binding generation and tests.

macOS 10.14 (or older) and Xcode 9 are required for producing 32-bit builds. Xcode 12 is required to compile for ARM64.
