# Compile Result
|Platform|Pass|
|:-|-:|
|macOS(13.6.2 arm64),cmake(3.31.3),Homebrew clang(19.1.7)|✔|
|ubuntu(22.04 amd64),cmake(3.22),GCC(11.4.0)|✔|

## ubuntu compile setup
Use gcc from apt.

## macOS compile setup
Use llvm & lld from homebrew.

When building from vscode, add the following to `.vscode/tasks.json`
```json
{
	"version": "2.0.0",
	"tasks": [
		{
			"label": "CMake: configure",
			"type": "shell",
			"command": "cmake",
			"args": [
				"-S",
				".",
				"-B",
				"build",
				"-DCMAKE_OSX_DEPLOYMENT_TARGET=13.7.0",		// ignore lld warning
				"-DCMAKE_EXPORT_COMPILE_COMMANDS=ON",		// generate cache for clangd
				"-DCMAKE_BUILD_TYPE=Debug",
			],
			"options": {
				"cwd": "${workspaceFolder}",
				"env": {
					"CC": "/opt/homebrew/opt/llvm/bin/clang",
					"CXX": "/opt/homebrew/opt/llvm/bin/clang++",
					"LDFLAGS": "-L/opt/homebrew/opt/llvm/lib -L/opt/homebrew/opt/llvm/lib/unwind -fuse-ld=lld",
					"PKG_CONFIG_PATH": "",
				}
			},
			"group": "build",
		},
		{
			"label": "CMake: build all",
			"type": "shell",
			"command": "cmake",
			"args": [
				"--build",
				"build",
			],
			"group": "build",
		}
	]
}
```
You can also setup `.clangd` in the project root path
```yaml
CompileFlags:
  CompilationDatabase: build/
InlayHints:
  Enabled: No
```
When building from shell, add the env variables in the project root path
```shell
export CC="/opt/homebrew/opt/llvm/bin/clang"
export CXX="/opt/homebrew/opt/llvm/bin/clang++"
export CFLAGS="-I$(pwd)/.build-tool/install/include"
export CXXFLAGS="$CFLAGS"
export LDFLAGS="-L$(pwd)/.build-tool/install/lib -L/opt/homebrew/opt/llvm/lib -L/opt/homebrew/opt/llvm/lib/unwind -fuse-ld=lld"
export PKG_CONFIG_PATH="$(pwd)/.build-tool/install/lib/pkgconfig"
```

# Usage

First, run `gSI` to pull down submodules, and then run `.build-tool/build.sh --all`.
All the dependent libraries will be installed to `.build-tool/install`.

Generate cmake binary directory:
```shell
cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug
```

Build for the specific target(append `-j4` if want to speedup):
```shell
cmake --build build --target main
```

or install/uninstall:
```shell
cmake --build build --target install
cmake --build build --target uninstall
```

or clean:
```shell
cmake --build build --target clean
```

or all:
```shell
cmake --build build
ctest --test-dir build
```
