FTBFS boinc-client 7.22.0: gzread

[jengelh]

Describe the bug (Observed behavior)

As part of the make routine of the just-released 7.22.0:

Steps To Reproduce

1. I think it may involve building with -Wl,--as-needed.

Expected behavior

Include what you use. Let the build succeed.

boinc_client_LDADD = $(LIBBOINC) $(LIBBOINC_CRYPT) $(BOINC_EXTRA_LIBS) $(PTHREAD_LIBS)

This line is missing -lz (or a suitable call to pkgconfig zlib).

System Information

• OS: openSUSE Tumbleweed 20230122

Hello @jengelh,
thank you for the report.
Could you please share your configure log?
I believe I know why this happens but I need to be sure.

[jengelh]

…and within hours of the report, it no longer reproduces. (Due to ephemereal buildroots, there is no way to see what happened, either.)

This ticket looks similar to #3205, and I believe I have a solution for this issue: #5071
