Template for a CMake project that builds Faust .dsp files into headless Linux VST 2 plugins using a cross-compilation toolchain.
Originally developed and tested for usage with Elk Audio OS but could be used in similar contexts as well.
Inspired by the faust2faustvst script by A. Graef included in the standard Faust distribution. The rationale behind this CMake template is to have something that works in a cross-compilation environment. CMake is supported by Yocto/bitbake and similar tools and it is much easier to maintain in this respect to hand-written build scripts.
Requirements:
- Faust installed on your host machine (not included in Elk Audio OS toolchain). Tested with Faust 2.15.11
- Cross-compilation environment with g++ version with C++17 support and Boost libraries
Put the .dsp files you want to compile in the faust-code subdirectory, or in another path specified by the CMake variable FAUST_SOURCES_DIR.
The VsT 2.4 SDK must be provided in order to build the plugins. The SDK can be copied into the root of the repository or to the path specified by the CMake variable VST2_SDK_PATH.
Then compile with standard CMake workflow, e.g.
mkdir build && cd build
cmake ..
ccmake .. (to eventually change CMake options)
make
The other options available, i.e. those starting with FAUST_*, are the relevant ones (for a headless build) in the original faust2faustvst script.
