Notes:
1. `cdrom/cdxa` and `sound/spustream` do not come with example audio files. In
order to run these examples you'll have to provide your own files (and, in
the case of `spustream`, convert them using the included Python script) and
build the CD image manually.
2. The `lowlevel/cartrom` example is outdated and does not use SDK libraries.
It is kept for reference purposes only.
## Building the examples
The instructions below assume that PSn00bSDK, CMake 3.20+ and a GCC toolchain
are already installed. Refer to the [installation guide](../doc/installation.md)
for details.
**NOTE**: all examples are compiled by default when building the PSn00bSDK
libraries and tools (check the `build/examples` directory). These instructions
are for rebuilding the examples *after* the SDK has been installed.
1. Copy the contents of this directory (`share/psn00bsdk/examples` within the
PSn00bSDK installation directory) to your home directory or to another
folder you have write access to.
2. Configure and build the examples by running:
```bash
cmake -S . -B ./build -G "Ninja" -DCMAKE_TOOLCHAIN_FILE=<INSTALL_PATH>/lib/libpsn00b/cmake/sdk.cmake
cmake --build ./build
```
Replace `<INSTALL_PATH>` with the installation prefix you chose when
installing the SDK (usually `C:\Program Files\PSn00bSDK` or `/usr/local`,
so the full path to `sdk.cmake` would be
`C:\Program Files\PSn00bSDK\lib\libpsn00b\cmake\sdk.cmake` or
`/usr/local/lib/libpsn00b/cmake/sdk.cmake` respectively).
Add `-DPSN00BSDK_TARGET=mipsel-unknown-elf` to the first command if your
toolchain targets `mipsel-unknown-elf` rather than `mipsel-none-elf`. If you
can't get Ninja to work or don't have it installed, you can also replace
`-G "Ninja"` with `-G "Unix Makefiles"` (`-G "MSYS Makefiles"` on Windows)
to build using `make` instead.
This should create a `build` directory whose structure mirrors the one of
the parent directory, with each subfolder containing built executables and
CD images for each example.
