Bug 78741

That's strange. Can you provide the full output from ./configure && make V=1 ?

configure log and make log

Can't reproduce this. This seems to be some issue with your local installation.

This issue is being tracked upstream already: https://bugs.launchpad.net/ubuntu/+source/attr/+bug/1288091

If anybody knows of a workaround, I would love to hear about it.

Removed libattr's <attr/xattr.h> and switched to glibc's <sys/xattr.h>:

Please check if that fixes the issue. Thanks.

It works now, thank you
