Comment 0 for bug 1647204

1.8.0-2 synced from debian in Zesty Zapus 17.04 fails to build on all architectures from source with the error:

checking whether a simple qt program can be built... no
configure: error:
***
*** Qt5 (Qt5Core) is required for Qt binding.
***

The packages builds without this issue in debian unstable.

A little experimentation shows that is a ubuntu sbuild/pbuilder and ppa, setting -pie in the hardening options allows the build to proceed with the Qt bindings building properly.

Not being overly familiar with the hardening, I am unsure if dropping that feature set is relatively harmless, or massively undesirable and potentially harmful.

However, in a ppa build, but NOT in my local sbuild/pbuilder chroot, the resulting build then hangs on the (python?) tests on starting or stopping gpg-agent, and the build is eventually killed due to inactivity after 150 mins as follows
