Build from Source

Install Dependencies

Please make sure Clang (AppleClang 16+ or LLVM/Clang 17+), cmake 3.25+, ninja are installed and configured on your OS.

On Linux, you can install the remaining dependencies with the following command:

sudo apt-get update && sudo apt install libasound2-dev libx11-dev libxcomposite-dev libxcursor-dev libxext-dev libxinerama-dev libxrandr-dev libxrender-dev libfreetype-dev libfontconfig1-dev libxi-dev

Clone and Build

Once you have set up the environment, you can clone the ZL Splitter code, populate all submodules, then configure & build the code. Set ZL_JUCE_FORMATS to the desired formats, e.g., "VST3;LV2" on Linux/Windows or "VST3;AU" on macOS. Set ZL_HWY_STATIC_TARGET to SSE2 for baseline x86-64, SSE4 or AVX2 for compatible x86-64 processors, or NEON for ARM64. Build each architecture separately; the example below targets x86-64.

git clone https://github.com/ZL-Audio/ZLSplitter
cd ZLSplitter
git submodule update --init --recursive
cmake -B Builds -G Ninja -DCMAKE_BUILD_TYPE=Release -DZL_JUCE_FORMATS="VST3;LV2" -DZL_HWY_STATIC_TARGET="NEON" .
cmake --build Builds --config Release

After building, the plugins should have been copied to the corresponding folders. If you want to disable the copy process, you can pass -DZL_JUCE_COPY_PLUGIN=FALSE, find the binary folders under Builds/ZLSplitter_artefacts/Release and copy them manually.

If there are multiple compilers on your OS, you may need to pass extra flags to make sure that cmake uses LLVM/Clang. On Linux, you may pass -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++. On Windows, you may pass -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl.

AAX plug-ins need to be digitally signed using PACE Anti-Piracy's signing tools before they will run in commercially available versions of Pro Tools.
