SDL_GameControllerHasRumble is undefine
Fail to build joy

[mor2code]

focal 20.04 SDL version is 20.10, it does not have SDL_GameControllerHasRumble, function was implemented at SDL 2.18.

I have replaced the call with SDL_GameControllerRumble sending zeros in all 3 parameters it should have same effect.

current:
if (SDL_GameControllerHasRumble(game_controller_)) {
change to :
if (0==SDL_GameControllerRumble(game_controller_, 0, 0, 0)) {

for backward compatibility please don't use SDL_GameControllerHasRumble.

Same problem for me when building ROS Humble from source in Ubuntu 20.04 Focal (a Tier 3 platform):

[ 50%] Building CXX object CMakeFiles/game_controller.dir/src/game_controller.cpp.o

Installed versions:

$ dpkg -l | grep libsdl2
ii  libsdl2-2.0-0:amd64                                 2.0.10+dfsg1-3                        amd64        Simple DirectMedia Layer
ii  libsdl2-dev:amd64                                   2.0.10+dfsg1-3                        amd64        Simple DirectMedia Layer development files

and sdl2_vendor selects the system version by default.

If this is the only detail, then I agree with @mor2code that the joy package should probably be kept backwards-compatible by either using the old API or by compiling conditionally (the version can be checked by including SDL2/SDL_version.h).

I don't see how #270 would solve the problem (and it does not) as long as SDL2_FOUND is true and we use the system version. I tested that patch, without success.

The pull request that introduced the new API: #258

This repository also has a humble-devel branch that is not affected, but the rosdistro index and https://index.ros.org/p/joy/#humble point to the ros2 branch for Humble?

Closing this as it was fixed by #273 .

Yeah, we can probably just remove that humble-devel branch, as we aren't currently using it (as far as I know). I'll take a quick look and then do that.
