As of writing (2024/03/15) building for loongarch considered to be highly experimental. Not all features can be enabled.
|
||
|
|
|
||
|
|
This is for the case when you have Linux machine and want to use it to build `clickhouse` binary that will run on another Linux machine with LOONGARCH64 CPU architecture. This is intended for continuous integration checks that run on Linux servers.
|
||
|
|
|
||
|
|
The cross-build for LOONGARCH64 is based on the [Build instructions](../development/build.md), follow them first.
|
||
|
|
|
||
|
|
## Install Clang-18
|
||
|
|
|
||
|
|
Follow the instructions from https://apt.llvm.org/ for your Ubuntu or Debian setup or do
|
||
|
|
```
|
||
|
|
sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Build ClickHouse {#build-clickhouse}
|
||
|
|
|
||
|
|
|
||
|
|
The llvm version required for building must be greater than or equal to 18.1.0.
|
||
|
|
``` bash
|
||
|
|
cd ClickHouse
|
||
|
|
mkdir build-loongarch64
|
||
|
|
CC=clang-18 CXX=clang++-18 cmake . -Bbuild-loongarch64 -G Ninja -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-loongarch64.cmake
|
||
|
|
ninja -C build-loongarch64
|
||
|
|
```
|
||
|
|
|
||
|
|
The resulting binary will run only on Linux with the LOONGARCH64 CPU architecture.
