CMake Error at /usr/lib/cmake/avogadrolibs/AvogadroLibsTargets.cmake:548 (message):
  The imported target "AvogadroQtGui" references the file

     "/usr/lib/libAvogadroQtGui.so.1.95.1"

  but this file does not exist.  Possible reasons include:

(This was previously a comment inquiring about an error when installing via yay -S avogadro2-git, which failed at the testing stage.)

I have since done a bit more digging with a clearer head. The issue is essentially that the test seem to fail even when the resulting installed app functions as intended (via berquist's comment below). As such, you'll need to use a flag or option to avoid the tests with whatever installation method you intend to use (yay, makepgk, etc.).

For yay, you need to pass the --nocheck flag through yay to makepkg via mflags. For example, I built successfully using:

yay -S avogadro2-git --mflags "--nocheck"

The software builds, but does not open any structures. Did anyone have the same problem?

Another somewhat related question: is there any PKBGUILD for Avogadro 1 that currently works?

it should depend on python2-setuptools

Please, get rid of CFLAGS and CXXFLAGS (see my comment on avogadrolibs-git).

You should run makepkg with --nocheck. I don't know how to use aursync but I assume it has some method of disabling tests.

I should also say that the final app works as expected.

When I try to build this I get following error(s):

Building is completed to 100% but then:

Aborting... ==> ERROR: Build failed, check /var/lib/aurbuild/x86_64/vidar/build

What am I missing? I tried to install with aursync.

This happens when using avogadrolibs and not avogadrolibs-git. I've fixed all the git PKGBUILDs, and made avogadrolibs-git a hard dependency. Frankly one should not be using the official avogadrolibs since it isn't properly built for Avogadro 2, and it is based on an release from December 2016. Anyone building on top of Open Chemistry should use bleeding edge releases if possible.
