On Darwin, the build script tries to 1. use llvm-objcopy/llvm-strip from $PATH, 2. if not found by 1., use standard objcopy/strip from $PATH The brew install instructions recommends to set $PATH to brew's binary dir, so 2. will find something (assuming binutils is installed from brew). If $PATH additionally points to brew's LLVM binary dir (which is different from brew's binary dir), 1. will find the llvm versions of the tools. This commit removes additional logic which repeats above steps in a more implicit way by calling brew internally and figuring out the paths once more if 1. and 2. cannot find them in the $PATH. This removes duplication and simplifies the script. Maybe it even helps with reproducibility.

# How to Build ClickHouse on Mac OS X
|
||
|
||
:::info You don't have to build ClickHouse yourself!
|
||
You can install pre-built ClickHouse as described in [Quick Start](https://clickhouse.com/#quick-start). Follow **macOS (Intel)** or **macOS (Apple silicon)** installation instructions.
|
||
:::
|
||
|
||
The build works on x86_64 (Intel) and arm64 (Apple Silicon) based on macOS 10.15 (Catalina) or higher with Homebrew's vanilla Clang.
|
||
|
||
:::note
|
||
It is also possible to compile with Apple's XCode `apple-clang` or Homebrew's `gcc`, but it's strongly discouraged.
|
||
:::
|
||
|
||
## Install Homebrew {#install-homebrew}
|
||
|
||
First install [Homebrew](https://brew.sh/)
|
||
|
||
## For Apple's Clang (discouraged): Install Xcode and Command Line Tools {#install-xcode-and-command-line-tools}
|
||
|
||
Install the latest [Xcode](https://apps.apple.com/am/app/xcode/id497799835?mt=12) from App Store.
|
||
|
||
Open it at least once to accept the end-user license agreement and automatically install the required components.
|
||
|
||
Then, make sure that the latest Command Line Tools are installed and selected in the system:
|
||
|
||
``` bash
|
||
sudo rm -rf /Library/Developer/CommandLineTools
|
||
sudo xcode-select --install
|
||
```
|
||
|
||
## Install Required Compilers, Tools, and Libraries {#install-required-compilers-tools-and-libraries}
|
||
|
||
``` bash
|
||
brew update
|
||
brew install cmake ninja libtool gettext llvm gcc binutils
|
||
```
|
||
|
||
## Checkout ClickHouse Sources {#checkout-clickhouse-sources}
|
||
|
||
``` bash
|
||
git clone --recursive git@github.com:ClickHouse/ClickHouse.git
|
||
# ...alternatively, you can use https://github.com/ClickHouse/ClickHouse.git as the repo URL.
|
||
```
|
||
|
||
## Build ClickHouse {#build-clickhouse}
|
||
|
||
To build using Homebrew's vanilla Clang compiler (the only **recommended** way):
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
mkdir build
|
||
export PATH=$(brew --prefix llvm)/bin:$PATH
|
||
export CC=$(brew --prefix llvm)/bin/clang
|
||
export CXX=$(brew --prefix llvm)/bin/clang++
|
||
cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -S . -B build
|
||
cmake --build build
|
||
# The resulting binary will be created at: build/programs/clickhouse
|
||
```
|
||
|
||
To build using Xcode's native AppleClang compiler in Xcode IDE (this option is only for development builds and workflows, and is **not recommended** unless you know what you are doing):
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
rm -rf build
|
||
mkdir build
|
||
cd build
|
||
XCODE_IDE=1 ALLOW_APPLECLANG=1 cmake -G Xcode -DCMAKE_BUILD_TYPE=Debug -DENABLE_JEMALLOC=OFF ..
|
||
cmake --open .
|
||
# ...then, in Xcode IDE select ALL_BUILD scheme and start the building process.
|
||
# The resulting binary will be created at: ./programs/Debug/clickhouse
|
||
```
|
||
|
||
To build using Homebrew's vanilla GCC compiler (this option is only for development experiments, and is **absolutely not recommended** unless you really know what you are doing):
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
mkdir build
|
||
export PATH=$(brew --prefix binutils)/bin:$PATH
|
||
export PATH=$(brew --prefix gcc)/bin:$PATH
|
||
export CC=$(brew --prefix gcc)/bin/gcc-11
|
||
export CXX=$(brew --prefix gcc)/bin/g++-11
|
||
cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -S . -B build
|
||
cmake --build build
|
||
# The resulting binary will be created at: build/programs/clickhouse
|
||
```
|
||
|
||
## Caveats {#caveats}
|
||
|
||
If you intend to run `clickhouse-server`, make sure to increase the system’s maxfiles variable.
|
||
|
||
:::note
|
||
You’ll need to use sudo.
|
||
:::
|
||
|
||
To do so, create the `/Library/LaunchDaemons/limit.maxfiles.plist` file with the following content:
|
||
|
||
``` xml
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
|
||
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
|
||
<plist version="1.0">
|
||
<dict>
|
||
<key>Label</key>
|
||
<string>limit.maxfiles</string>
|
||
<key>ProgramArguments</key>
|
||
<array>
|
||
<string>launchctl</string>
|
||
<string>limit</string>
|
||
<string>maxfiles</string>
|
||
<string>524288</string>
|
||
<string>524288</string>
|
||
</array>
|
||
<key>RunAtLoad</key>
|
||
<true/>
|
||
<key>ServiceIPC</key>
|
||
<false/>
|
||
</dict>
|
||
</plist>
|
||
```
|
||
|
||
Give the file correct permissions:
|
||
|
||
``` bash
|
||
sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
Validate that the file is correct:
|
||
|
||
``` bash
|
||
plutil /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
Load the file (or reboot):
|
||
|
||
``` bash
|
||
sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
To check if it’s working, use the `ulimit -n` or `launchctl limit maxfiles` commands.
|
||
|
||
## Running ClickHouse server
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
./build/programs/clickhouse-server --config-file ./programs/server/config.xml
|
||
```
