I'm trying to add the ability to read registry keys to winejoystick.drv using functions like RegQueryValueExA, RegOpenKeyA, and RegCloseKey. However, I am getting linker errors where they are showing up as undefined symbols. The changed files are attached. The functions get_app_key, get_config_key, and device_disabled_registry are copied from various files in dinput and I assumed I needed to import advapi32 in the makefile.in since that's what type the aforementioned registry functions are, but I'm obviously misunderstanding how this works. Any help appreciated!
