PSN00bSDK Builder

By Alex Free

Automatically build the PSN00bSDK by Lameguy64 on Linux or Windows in a self-contained manner, to not affect anything else on your system. A psn00b-env command is provided which adds all the tools installed to /usr/local/psn00bsdk to your $PATH, and additionally sets the proper PSN00BSDK_LIBS envar to enable use of the SDK in the current shell.

The PSN00bsdk builder installs everything to /usr/local/psn00bsdk. PSN00bSDK Builder currently will setup mipsel-none-elf GCC 12.2.0/Binutils 2.40 with the latest git commit of the PSN00bSDK at time of script execution.

Supported Operating Systems:

1) If your on Windows, install MSYS2 and start the MSYS2 MSYS shell. On Linux, open your terminal.

2) Download the latest release and cd into the extracted directory.

3) Execute ./ This will take quite awhile to complete since on the toolchain and sdk will are all compiled from source.

4) To use the SDK/toolchain, execute the psn00b-env to add the toolchain/sdk to your $PATH, and to set the PSN00BSDK_LIBS env var. You’ll need to do this every time you open a new Terminal window or MSYS2 MSYS window).

5) After running the ./ script, you can use the ./ script to update the PSN00bSDK to the latest version at any time. This command does not rebuild the toolchain, which is much faster then running ./ again. To rebuild the toolchain and the sdk all over again, execute the ./ script once again.

Tip 1: You can also use WSL on Windows instead of MSYS2. Just follow the linux specific instructions if using WSL.

Tip 2: If you want to remove anything installed by either the or scripts at any time, just rm -rf /usr/local/psn00bsdk. The script in fact already does this when started before rebuilding everything from source.
