PPSSPP on WSL
WSL or Windows Services for Linux is a convenient way to run a Linux VM on Windows. It's well-integrated and quite convenient.
Recently, it has even added graphics support and it's now possible to build and run PPSSPP on WSL2, which can be very useful for debugging - especially for running various tools that only exist or work better on Linux like valgrind, address-sanitizer etc.
Tips
-
Install VSCode on Windows (not in your WSL VM!)
-
Check out the PPSSPP repository:
git clone [email protected]:hrydgard/ppsspp.git --recursive
-
Install the usual dependencies documented here (plus cmake).
-
Install at least the following VSCode extensions:
- CodeLLDB (a debugger)
- WSL
- C/C++ Extension Pack
In your WSL directory where you checked out the PPSSPP git repo, from terminal, just:
code .
PPSSPP now provides .vscode/tasks.json and .vscode/launch.json for your convenience, so debugging should "just work".
The build task just runs a debug build, important to be aware of. Change it to --release or add an additional task if desired.
Valgrind
Here's an example where we both use suppressions, and generate new ones (that you can then take from suppressions.log and simplify and copy to valgrind-wsl2.supp):
valgrind --suppressions=SDL/valgrind-wsl2.supp --gen-suppressions=all --log-file=suppressions.log build/PPSSPPSDL
