[cups] Sending mail from a CentOS7 virtual machine to Fuji Xerox ApeosPort-IV C4475 problem revisted

[Zdenek Dohnal]

I looked in our knowledge base articles and found out:

Ian, do you find such logs in journal?

|||If you do, then you encountered known problem - you have these
filters from fxlinuxprint package from vendor, correct? These rpms seems
to be built with different versions of required packages than we have in
CentOS, so when you try to run the filter, it segfaults because of
binary incompatibility. The solution would be to rebuild with packages
from CentOS, but I cannot do the rebuild, because it is not in CentOS
distribution (because nobody puts it in distribution...).

|But the project is open source, it seems -
https://github.com/rogers0/fxlinuxprint - you can compile it for
yourself and segfault would go away. I bookmarked the package for adding
into Fedora, so I hope I will fix it permanently in the future (but the
path is long - first it needs to be added in Fedora, then get it into
RHEL/CentOS, which needs agreement from other people than me..., so I'm
sorry, I wouldn't expect to solve it quickly...)
