Checking for the header is NOT sufficient when utilizing its shared library symbols. Look it up with pkg-config explicitly, and explicitly add it to ensure that at runtime, libppd has its own DT_NEEDED dependency on libz.so; if libppd successfully links at all -- not a given, if -Wl,-no-undefined is used -- then it *may* transitively get libz.so from its recursive dependencies, but this is no guarantee at all.

No big deal, the important thing is to get it in before the next tagged release. |
