[Linux] Build failure

[Shoegzer]

Validation

• [X] I've read the FAQ.
• [X] The Xenia build used is from the master branch (not MLBS/AlexVS/Canary/pull requests, etc.)
• [X] This issue isn't for tech support (help with Xenia).
• [X] If this issue occurs in a specific game, I've done analysis to locate the faulty subsystem of the emulator and a potential reason in it.
• [X] I've checked if this issue hasn't already been reported.
• [X] My device meets the minimum requirements: https://github.com/xenia-project/xenia/wiki/Quickstart#system-requirements
• [X] (If building) I have read the building doc: https://github.com/xenia-project/xenia/blob/master/docs/building.md

Describe what's going wrong

Xenia fails to build under linux for reasons related to SDL, specifically throwing the build-time exception:

/usr/bin/ld: bin/Linux/Debug/libxenia-hid-sdl.a(sdl_input_driver.o): in function `xe::hid::sdl::SDLInputDriver::OnControllerDeviceAdded(SDL_Event const&)':
/home/testing/Desktop/xenia/xenia/build/../src/xenia/hid/sdl/sdl_input_driver.cc:441: undefined reference to `SDL_GameControllerGetType'
/usr/bin/ld: /home/testing/Desktop/xenia/xenia/build/../src/xenia/hid/sdl/sdl_input_driver.cc:467: undefined reference to `SDL_GameControllerSetPlayerIndex'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [xenia-hid-demo.make:119: bin/Linux/Debug/xenia-hid-demo] Error 1
make: *** [Makefile:368: xenia-hid-demo] Error 2

Test system is Linux Mint 20.3 / kernel 5.15, using gcc-11.1.0

Describe what should happen

Xenia should compile. Build failure encountered with this commit. Last known good compile with this commit.

If applicable, provide a callstack here, especially for crashes

Update: After updating test system from Linux Mint 20.3 > 21.0, xenia now builds. However, I'm only getting a debug binary (no release binary). I'm just running xb-setup and xb-build. @JoelLinn can I assume this is normal given the experimenatal nature of Linux support?

[JoelLinn]

As with most build systems you need to select a configuration. Check the documentation on xb build

[Shoegzer]

Got it, thanks. I assumed the release binary would be built by default but you're right, the xb build doc suggests otherwise and of course provides the options. Closing this issue now.
