This is intended for continuous integration checks that run on Linux servers. If you want to build ClickHouse directly on macOS, then proceed with [another instruction](../development/build-osx.md). The cross-build for macOS is based on the [Build instructions](../development/build.md), follow them first. The following sections provide a walk-through for building ClickHouse for `x86_64` macOS. If you’re targeting ARM architecture, simply substitute all occurrences of `x86_64` with `aarch64`. For example, replace `x86_64-apple-darwin` with `aarch64-apple-darwin` throughout the steps. ## Install Clang-17 Follow the instructions from https://apt.llvm.org/ for your Ubuntu or Debian setup. For example the commands for Bionic are like: ``` bash sudo echo "deb [trusted=yes] http://apt.llvm.org/bionic/ llvm-toolchain-bionic-17 main" >> /etc/apt/sources.list sudo apt-get install clang-17 ``` ## Install Cross-Compilation Toolset {#install-cross-compilation-toolset} Let’s remember the path where we install `cctools` as ${CCTOOLS} ``` bash export CCTOOLS=$(cd ~/cctools && pwd) mkdir ${CCTOOLS} cd ${CCTOOLS} git clone --depth=1 https://github.com/tpoechtrager/apple-libtapi.git cd apple-libtapi INSTALLPREFIX=${CCTOOLS} ./build.sh ./install.sh cd .. git clone --depth=1 https://github.com/tpoechtrager/cctools-port.git cd cctools-port/cctools ./configure --prefix=$(readlink -f ${CCTOOLS}) --with-libtapi=$(readlink -f ${CCTOOLS}) --target=x86_64-apple-darwin make install ``` Also, we need to download macOS X SDK into the working tree. ``` bash cd ClickHouse/cmake/toolchain/darwin-x86_64 curl -L 'https://github.com/phracker/MacOSX-SDKs/releases/download/11.3/MacOSX11.0.sdk.tar.xz' | tar xJ --strip-components=1 ``` ## Build ClickHouse {#build-clickhouse} ``` bash cd ClickHouse mkdir build-darwin cd build-darwin CC=clang-17 CXX=clang++-17 cmake -DCMAKE_AR:FILEPATH=${CCTOOLS}/bin/x86_64-apple-darwin-ar -DCMAKE_INSTALL_NAME_TOOL=${CCTOOLS}/bin/x86_64-apple-darwin-install_name_tool -DCMAKE_RANLIB:FILEPATH=${CCTOOLS}/bin/x86_64-apple-darwin-ranlib -DLINKER_NAME=${CCTOOLS}/bin/x86_64-apple-darwin-ld -DCMAKE_TOOLCHAIN_FILE=cmake/darwin/toolchain-x86_64.cmake .. ninja ``` The resulting binary will have a Mach-O executable format and can’t be run on Linux.
