Hello fellow users.
I'm back to player and stage after a few years of hiatus.
My last work has been a Dempster-Shafer based hexagonal mapping algorithm.
Didn't work that good as DS tends to saturate as everyone knows but anyway...
I had my nice program reading data from player and stage through the sonar interface.
Was using the simple world having removed the laser to better see the sonars I was plotting.
Now I installed the latest player trunk and latest stage trunk (3.1.0-svn and 4.1.1) and my old program doesn't want to work.
When I launch it, it can't find the sonar interface.
Player reports a request for an unknown interface
warning : skipping subscription to unknown device sonar:0
Now this seems coherent with the fact that the simple.cfg has
provides [ "positon2d:0" "ranger:0" "ranger:1" ]
But if I change the provides with
provides [ "positon2d:0" "sonar:0" "ranger:0" ]
player quits saying
Stage plugin: 6665.sonar.0 is err: error: stage driver doesn't support interface type 5
So apparently stage doesn't support sonar anymore?
I tried reverting to stage 3.2.2, 3.2.1, and even 3.2.0 but got the same results.
If that's the case my program should not compile, at least for how I view it if an interface isn't supported anymore headers shouldn't be available.
But it compiles.
So what am I missing here?
My stupid program does the following
client = playerc_client_create(NULL, player_host, player_port);
if (0 != playerc_client_connect(client))
// Create and subscribe to a position2d device.
position2d = playerc_position2d_create(client, 0);
if (playerc_position2d_subscribe(position2d, PLAYER_OPEN_MODE))
if (playerc_sonar_subscribe(sonar, PLAYER_OPEN_MODE))
Then lots of geometric calculations with the sonar data.
Any help would be greatly appreciated.
