Not at the moment. Is the feedback joystick support robust under Linux now? :slight_smile:

I will buy Logitech Formula Force today.
In /usr/src/linux/Documentation/input/joystick.txt I found this driving wheel
is supported by kernel (haven’t checked sources yet).On Thu, Aug 22, 2002 at 08:34:16PM -0700, Sam Lantinga wrote:

I have a MS Sidewinder Forcefeedback Pro and as far as I know there’s no
code anywhere to do force feedback within the driver, but I could be
wrong. I’m just assuming as I’ve never heard of a Linux app that used
force feedback. Somebody tell me I’m wrong, I’d like to start using it.

Looks like in /usr/src/linux/drivers/char/joystick/iforce.c there is a lot of
stuff about force feedback. But this is driver for my Logitech, not MS. And I
am going to play tonight :-)On Fri, Aug 23, 2002 at 01:36:06AM -0700, Chris Thielen wrote:

Hmm, not especially encouraging:

At the moment, only I-Force devices are supported, and not officially. That
means I had to find out how the protocol works on my own. Of course, the
information I managed to grasp is far from being complete, and I can not
guarranty that this driver will work for you.
…
Before you start, let me WARN you that some devices shake violently during the
initialisation phase. This happens for example with my “AVB Top Shot Pegasus”.
To stop this annoying behaviour, move you joystick to its limits. Anyway, you
should keep a hand on your device, in order to avoid it to brake down if
something goes wrong.

Heheh.

Hi,

This is the homepage for linux force feedback driver :
http://user.it.uu.se/~johannd/projects/ff/index.shtml

This is the only game I know of using force feedback under linux :

The site (http://user.it.uu.se/~johannd/projects/ff/links.shtml)
also lists Vegastrike, http://vegastrike.sourceforge.net/ , as another
game supporting force feedback.
Support for MS Sidewinder Force 2 is available through a separate
patch from http://madfab.free.fr/ff/On Fri, 23 Aug 2002, black_knight wrote:

Is smpeg still being maintained?
I got some fixes to the smpeg library. I posted the problem (with
compiling using GCC 3.2) on this list a few days ago.
As a reference, I used cvs sources checked out from
cvs.lokigames.com. I obtained a copy before the CVS server went down.
The Makefile.am needs a line that says :
CXXLD = cc
and then ‘libsmpeg_la_LDFLAGS = ’ needs extra ‘-lstdc++’.
I don’t know how portable it is but it fixes the problem. If you
are using the CVS sources and automake 1.6.x, you may want to add
’AM_PROG_AS’ to configure.in.
Is the maintainer of smpeg on this list?
Thanks.

That would be me, I think.

Please pull from the CVS at icculus.org…the Loki CVS is dead.

cvs -z3 -d:pserver:anonymous at cvs.icculus.org:/cvs/cvsroot co smpeg

(password is “anonymous”, without the quotes.)

If it’s still broken, we’ll patch it, but I did some autoconf work on it
awhile ago that might fix it.

Hi Ryan,

I am getting the same problems with the icculus.org cvs. I am

attaching a patch that does the following:

  • adds AM_PROG_AS to configure in order to fix:
    automake: video/Makefile.am: Assembler source seen but CCAS' not defined inconfigure.in’
    automake: video/Makefile.am: Assembler source seen but CCASFLAGS' not defined inconfigure.in’

  • changes linking from using g++ to gcc and then makes gcc use libstdc++.
    This fixes this error:
    .libs/libsmpeg.so: undefined reference to operator new[](unsigned)' .libs/libsmpeg.so: undefined reference tooperator delete(void*)’
    .libs/libsmpeg.so: undefined reference to __cxa_pure_virtual' .libs/libsmpeg.so: undefined reference tooperator delete’
    .libs/libsmpeg.so: undefined reference to `operator new(unsigned)'
    collect2: ld returned 1 exit status

There are also some files that automake requires. One of them is
’depcomp’. It can be copied from automake’s
share directory (/usr/share/automake/depcomp on my system). I don’t know
if it comes with automake version <1.6.x.
Files: INSTALL NEWS AUTHORS ChangeLog are also required but I might be
missing a flag to automake that surpresses this error.

Let me know if there are any problems.
