|
|
As of writing (2023/3/10) building for s390x considered to be experimental. Not all features can be enabled, has broken features and is currently under active development.
|
|
|
|
|
|
## Building
|
|
|
|
As s390x does not support boringssl, it uses OpenSSL and has two related build options.
|
|
- By default, the s390x build will dynamically link to OpenSSL libraries. It will build OpenSSL shared objects, so it's not necessary to install OpenSSL beforehand. (This option is recommended in all cases.)
|
|
- Another option is to build OpenSSL in-tree. In this case two build flags need to be supplied to cmake
|
|
```bash
|
|
-DENABLE_OPENSSL_DYNAMIC=0 -DENABLE_OPENSSL=1
|
|
```
|
|
|
|
These instructions assume that the host machine is x86_64 and has all the tooling required to build natively based on the [build instructions](../development/build.md). It also assumes that the host is Ubuntu 22.04 but the following instructions should also work on Ubuntu 20.04.
|
|
|
|
In addition to installing the tooling used to build natively, the following additional packages need to be installed:
|
|
|
|
```bash
|
|
apt-get install binutils-s390x-linux-gnu libc6-dev-s390x-cross gcc-s390x-linux-gnu binfmt-support qemu-user-static
|
|
```
|
|
|
|
If you wish to cross compile rust code install the rust cross compile target for s390x:
|
|
```bash
|
|
rustup target add s390x-unknown-linux-gnu
|
|
```
|
|
|
|
To build for s390x:
|
|
```bash
|
|
cmake -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-s390x.cmake ..
|
|
ninja
|
|
```
|
|
|
|
## Running
|
|
|
|
Once built, the binary can be run with, eg.:
|
|
|
|
```bash
|
|
qemu-s390x-static -L /usr/s390x-linux-gnu ./clickhouse
|
|
```
|
|
|
|
## Debugging
|
|
|
|
Install LLDB:
|
|
|
|
```bash
|
|
apt-get install lldb-15
|
|
```
|
|
|
|
To Debug a s390x executable, run clickhouse using QEMU in debug mode:
|
|
|
|
```bash
|
|
qemu-s390x-static -g 31338 -L /usr/s390x-linux-gnu ./clickhouse
|
|
```
|
|
|
|
In another shell run LLDB and attach, replace `<Clickhouse Parent Directory>` and `<build directory>` with the values corresponding to your environment.
|
|
```bash
|
|
lldb-15
|
|
(lldb) target create ./clickhouse
|
|
Current executable set to '/<Clickhouse Parent Directory>/ClickHouse/<build directory>/programs/clickhouse' (s390x).
|
|
(lldb) settings set target.source-map <build directory> /<Clickhouse Parent Directory>/ClickHouse
|
|
(lldb) gdb-remote 31338

## Visual Studio Code integration
|
|
|
|
- [CodeLLDB extension](https://github.com/vadimcn/vscode-lldb) is required for visual debugging, the [Command Variable](https://github.com/rioj7/command-variable) extension can help dynamic launches if using [cmake variants](https://github.com/microsoft/vscode-cmake-tools/blob/main/docs/variants.md).
|
|
- Make sure to set the backend to your llvm installation eg. `"lldb.library": "/usr/lib/x86_64-linux-gnu/liblldb-15.so"`
|
|
- Launcher:
|
|
```json
|
|
{
|
|
"version": "0.2.0",
|
|
"configurations": [
|
|
{
|
|
"name": "Debug",
|
|
"type": "lldb",
|
|
"request": "custom",
|
|
"targetCreateCommands": ["target create ${command:cmake.launchTargetDirectory}/clickhouse"],
|
|
"processCreateCommands": ["settings set target.source-map ${input:targetdir} ${workspaceFolder}", "gdb-remote 31338"],
|
|
"sourceMap": { "${input:targetdir}": "${workspaceFolder}" },
|
|
}
|
|
],
|
|
"inputs": [
|
|
{
|
|
"id": "targetdir",
|
|
"type": "command",
|
|
"command": "extension.commandvariable.transform",
|
|
"args": {
|
|
"text": "${command:cmake.launchTargetDirectory}",
|
|
"find": ".*/([^/]+)/[^/]+$",
|
|
"replace": "$1"
|
|
}
|
|
}
|
|
]
|
|
}
|
|
```
|
|
- Make sure to run the clickhouse executable in debug mode prior to launch. (It is also possible to create a `preLaunchTask` that automates this) |
