CMake auto compile setup for libass.
Configured for (at the time this repo is set up):
- libass: 0.14.0
- fribidi: 1.0.5
- freetype: 2.10.0
- harfbuzz: 2.3.1
For an old version MSVC solution see libass-msvc.
Files in src/compat and some config headers are taken from libass-msvc, with necessary modifications.
The CMake scripts are written for MSVC. They may also work for other build toolchains, but I haven't tested that.
Requirements:
- CMake (>= 3.13)
- NASM (some recent version)
# Clone the repo and begin to work
git clone https://github.com/hozuki/libass-cmake
cd libass-cmake
# Initialize submodules
git submodule update --init --recursive
# Create and enter a build directory
mkdir build
cd build
# Generate build files
cmake -G "Visual Studio 15 2017 Win64" ..
# Fix the source files; see "Extra Steps"
# Build!
cmake --build . --target ass --Built binary (DLL) is located at build/cmake/bin.
Because of a known issue
(const int array length) in libass 0.14.0, you have to manually edit some source files
to successfully compile in MSVC.
In ass_outline.c:
Search for double mul[max_subdiv + 1]. For each hit change max_subdiv
to the constant assigned above.
In ass_render.c:
Search for ASS_Outline outline[n_outlines]. Change n_outlines to the constant assigned above.
