# How to Build ClickHouse on Mac OS X {#how-to-build-clickhouse-on-mac-os-x}
|
||
|
||
Build should work on Mac OS X 10.15 (Catalina).
|
||
|
||
## Install Homebrew {#install-homebrew}
|
||
|
||
``` bash
|
||
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
|
||
```
|
||
|
||
## Install Required Compilers, Tools, and Libraries {#install-required-compilers-tools-and-libraries}
|
||
|
||
``` bash
|
||
$ brew install cmake ninja libtool gettext llvm
|
||
```
|
||
|
||
## Checkout ClickHouse Sources {#checkout-clickhouse-sources}
|
||
|
||
``` bash
|
||
$ git clone --recursive git@github.com:ClickHouse/ClickHouse.git
|
||
```
|
||
|
||
or
|
||
|
||
``` bash
|
||
$ git clone --recursive https://github.com/ClickHouse/ClickHouse.git
|
||
|
||
$ cd ClickHouse
|
||
```
|
||
|
||
## Build ClickHouse {#build-clickhouse}
|
||
|
||
> Please note: ClickHouse doesn't support build with native Apple Clang compiler, we need use clang from LLVM.
|
||
|
||
``` bash
|
||
$ mkdir build
|
||
$ cd build
|
||
$ cmake .. -DCMAKE_C_COMPILER=`brew --prefix llvm`/bin/clang -DCMAKE_CXX_COMPILER=`brew --prefix llvm`/bin/clang++ -DCMAKE_PREFIX_PATH=`brew --prefix llvm`
|
||
$ ninja
|
||
$ cd ..
|
||
```
|
||
|
||
## Caveats {#caveats}
|
||
|
||
If you intend to run `clickhouse-server`, make sure to increase the system’s maxfiles variable.
|
||
|
||
!!! info "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>
|
||
```
|
||
|
||
Execute the following command:
|
||
|
||
``` bash
|
||
$ sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
Reboot.
|
||
|
||
To check if it’s working, you can use `ulimit -n` command.
