Re: Fwd: Problem with reprotest-kernel

Show all headers | View raw

After some further investigation, I have figured out a solution.
Changing the build dependency to the -dev package (from libzbar0 to
libzbar-dev) has fixed the failing reprotest-kernel job. I tried this
out after reading that ctypes.util.find_library is usually used to
lookup build-time dependencies rather than run-time dependencies.

Local builds and other reprotest variations work fine without the -dev
package. Can someone share some insight into why reprotest-kernel needs
the -dev package?

Thanks in advance
