we need a patch to make it build with sip 4.11.2

/build/src/avogadro-1.0.1/libavogadro/src/python/sip.cpp: In static member function 'static void* QClass_converters<T>::QClass_from_PyQt(PyObject*)':

avogadro-1.0.1-2-i686:
The _C_API object in the sip python module is invalid.
Could not initialize SIP API !
terminate called after throwing an instance of 'boost::python::error_already_set'
Aborted
Fedora 14 gives the same error as well

There has been a change in the sip API and avogadro do not suport it in the currect release:
there are three options:
a) Downgrade sip to 4.10.5-1.
b) Wait till the next release.
c) Apply the following path to avogadro ( http://bugs.gentoo.org/attachment.cgi?id=254359):

QClass_converters()

As a temporary solution I installed the 1.1 binary from http://avogadro.openmolecules.net/nightly/linux/unstable/. It works, but it is really unstable.

@ hseara
we already include that patch into avogadro

Sorry, I think I confused the patch. In the following link you can find the correct one:

http://gold.cryos.net:8080/#change,299

This patch has already been applied to the master. But until a new release appear no chance.

that link does not work. The last patch applied in avogadro is https://github.com/cryos/avogadro/commit/c3e2e3cba551de8c512c3f38e3b495b031cb0f9b
and we already applied it in our package

The last link from hseara works now and that patch appears to be the solution. I have not built it yet.

ok now it works and........we already have that patch in our package!

I still get this when trying to run, and I just did full update:

The _C_API object in the sip python module is invalid.
Could not initialize SIP API !
terminate called after throwing an instance of 'boost::python::error_already_set'

The patch applied for correcting SIP version is different from the one in the upstream. The patch applied in the upstream can be found in:
http://gold.cryos.net:8080/#change,299

Only one file has to be changed: avogadro/src/python/sip.cpp. No patch is needed for cmake/modules/PythonDeps.cmake.

What's going on with this? Are we waiting for an upstream fix?
I tried to look for a working patch on gold.cryos.net but the site takes several minutes to load a nearly empty page.

Considering that the package is completely unusable because of this, perhaps the severity should be higher than "low". ;)

Here's the Fedora bug report and an apparently working patch:
https://bugzilla.redhat.com/show_bug.cgi?id=642248

I applied the patch but the build fails:

Linking CXX executable ../../bin/avogadro
[ 95%] Built target avogadro-app
make: *** [all] Error 2
Aborting...

still no fix from upstream...
