Speakup and centOS

Speakup and centOS

[Tim Culhane]

Hi,

Does Speakup work with the centOS linux distribution.  I believe that centOS
is very similar to RedHat Enterprise Linux, so I'm interested in exploring
the possibility of using this distribution.

I read in the archive to this list that  somebody patched  the centOS kernel
with  Speakup a while back, but it wasn't an easy job.

Has anything changed since then?

Any help appreciated,

Tim

I've patched the rhel 3 and rhel 5 kernels before and it definitely isn't 
an easy job, because the rhel kernel is a hybrid kernel with backported 
features and bug fixes. It basically requires patching parts of the patch 
by hand.

On rhel 5 the problem is compounded by the fact that speakup no longer 
supports kernels prior to 2.6.24, as the kobject implementation changed in 
2.6.24. I did manage to get speakup to compile by trying to backport the 
new kobject implementation, similar to how it was done for the infiniband 
driver, but the speakup_dectlk driver is not able to detect the synth. I 
suspect the result would be the same with other drivers. I haven't tried 
software speech as I'm having trouble getting sound to work and I haven't 
had any time lately to work on it. Since my time is limited, I think I 
will install fc12 and then try my luck when rhel 6 is out, hopefully this 
spring.

I would recommend that the speakup developers remove the patches for the 
kernels before 2.6.24, as speakup will not compile against these kernels 
with the older kobject implementation. Or perhaps there is an older 
version of speakup in git that uses the older kobject implementation?

Hth,

Hi

I can't remember the version boundaries (2.6.19 - 2.6.25?) but the
speakup version is 2 from the cvs repos.  I'm not sure where they were
located.

You will not get git version 3 working on those older kernel versions.

four kinds of freedom, for the users of the software:

    * The freedom to run the program, for any purpose (freedom 0).
    * The freedom to study how the program works, and adapt it to your
needs (freedom 1). Access to the source code is a precondition for this.
    * The freedom to redistribute copies so you can help your neighbor
(freedom 2).
    * The freedom to improve the program, and release your improvements
to the public, so that the whole community benefits (freedom 3). Access
to the source code is a precondition for this.

I could be wrong, but my understanding is speakup 2 only supports kernels 
before 2.6.18. The patches do exist in the speakup 3.0 release for 2.6.18 
and up, but the current speakup release only supports kernels from 2.6.24 
and up, although I haven't actually tested this. My experience is that 
your best results will be with the latest kernel supported by speakup or a 
kernel from one of the distros the developers test against. I think that 
would be debian.
