janoc / libndofdev Goto Github PK

Thx for sharing this! Could place provide some instructions on how to install / use this?

Hi!

I am currently looking into the NDOF support for Firestorm, and I noticed that my XBox 360 pad's D-Pad isn't supported by libndofdev. The D-Pad gets recognized by SDL as a Joystick Hat, so I added support for that to libndofdev in my fork. This works fine for Linux, but I assume it won't do anything for other OSes.

So my question would be: Are hats recognized in the SL viewers at all on Windows / OSX? And should I expose hats as its own data field or map them to additional axes?

Any insight is greatly appreciated!
Thanks!

When building the libndofdev, a gcc warning occures:

cc -march=native -O2 -pipe -ggdb -c -o ndofdev.o ndofdev.c
ndofdev.c: In function ‘ndof_init_first’:
ndofdev.c:159:13: warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat=]
fprintf(stderr, "%s\n", explain_ioctl(fd, EVIOCGBIT(EV_REL, sizeof evtype_mask), evtype_mask));

This warning later turns into linking errors when building the secondlife client.

make -j8 'CFLAGS=-march=native -O2 -pipe -ggdb'

G'day. I just bought a shiny new SpaceMouse Pro today, and was wondering why no SL viewer could use it in Linux. Looks like it's too new for libndofdev. It's ID.product is 0xc62b, and it has 15 buttons. I might have a hack at fixing that tonight, or sleep on it and try to fix it tomorrow. Then I'll send you a patch if I get anywhere. Unless you beat me to it.
