Re: [COOT] Anyone got Coot to build on Fedora 12?

[Kevin Cowtan]

That's a fair question. Two reasons:
1. we are not Fedora centric, and
2. we need the nightly test data

The Fedora builds may be useful for Fedora users, however there are lots 
of non-Fedora users who rely on the same builds for distros of a similar 
age. A tar.gz package with all the dependencies is much more useful for 
such people.

The nightly tests are vital for ensuring the stability of the software. 
I have no idea if the Fedora RPMs even run the full test suite, let 
alone whether they do it nightly and where I can see the results. To be 
honest, I don't trust any Coot build for which I can't see the test 
results. There are too many things which can go wrong in subtle ways.

Why do you need to build guile?  yum install will give you 1.8.7?  And
if you want to build coot, an "official" coot submission for fedora is

Yes, but that means I have to mess with the build script. Given that
I'm doing multiple nightly builds across multiple platforms using the
build script from cvs, that's a problem. (Possible, but hard - and
need to check it doesn't break the other builds.)

If there is anyway of doing it by messing with the setup of the F12 
virtual machine, that would make life a lot easier.

Ah - looking at the patch again, I might get away with setting $CPP
to cpp -P in the .bashrc for the F12 machine. Will try that next.

I keep running into the c preprocessor problem when building guile 
listed here:
http://www.mail-archive.com/guile-de...@gnu.org/msg04783.html

It seems to be specific to Fedora's gcc 4.2.2, not to the upstream 
version. I tried using mcpp ( with ln -s /usr/bin/mccp 
/usr/local/bin/cpp ), but got the same result.

Is there any way to downgrade to a pre-F12 gcc?

The patch in the thread did the trick:
