Hi -

I do not believe that libtiff 3.8.2 is available for CentOS - only 3.6.1-8 and 3.6.1-10.

Remember, the goal of the CentOS project is not to provide bleeding edge software, so you may well get stuck with a slightly older version.

So the Asterisk AT Home gang that have built on Centos may have a real problem with spandsp.

Hi, RObert -

Well, no - not necessarily. Remember, we try to keep as close to RHEL as we can. In fact, I don't know of anything that's actually modified to be special for CentOS, aside from the usual.

The *@home guys probably built their own RPMs or installs for their setup. Even though it's based on CentOS, doesn't mean it has to BE CentOS - it could be a heavily modified version, including additional libraries which are mroe bleeding edge, e.g. libtiff-3.8.2.

Hope that clears some thigns up for you.

Thanks -dant

I know the Centos philosophy. I have a number of Centos servers here and building more. My mail server is Scalix running on Centos.

The AAH people (actually one person according to the sourceforge page) has done a great you adding the best Asterisk products on top of Centos. The libtiff-3.6.1-10 is from Centos 4.3. Sometime back Centos had libtiff 3.6.0 which the spandsp author said works well and that 3.6.1 is broken.

So those of us doing a new install are finding out that faxing is not working. So I (and many others) have to replace libtiff with either the older working version or 3.8.2. And when AAH 2.9 comes out with finally an update mechanism (instead of a reinstall), hopefully the right libtiff will be in the AAH iso.

Robert -

I am not doubting that you understand the CentOS philosophy by any means. Sometimes I find it necessary to do tweaks such as this one, for example with PHP and MySQL RPMs. I just try to keep it as close as I can to the "stock" CentOS distribution as I can, for obvious reasons.

Just wanted to clarify.

Thanks! -dant

We just did a security patch that might have taken care of issue 1 ... are those 2 separate issues?

Well I did the kernel update.

same libtiff ver: 3.6.1-10

Then rebuilt zaptel per general Asterisk instructions and I think things are rather broken. So off for now.

yes I see a kernel patch. That means rebuilding the zaptel libraries. The only library I have built. That is because it is all cookbook.

But I have a system that does not use zaptel. So I will start the update now and report back.

robert ... I think you are having asterisk issues, right.

oh yeah.

There will probably be other things required ... you will probably need to build it from the SRPM instead of using a regenerated RPM. FC is not going to have the proper shared libraries

Figures. I do not have a good track record of building from the SRPMs. I think I have hosed things up more than solved things.

Hey, I'm a crypto protocols guy (RFC 4423 finally published!). Not an OS guy. But I can't do my protocol work outside of my head and on paper without a working OS.....
