Subject: lib/pkgconfig/epics-base-linux-x86_64.pc: are -lca -ldbCore -lCom ... missing from Libs ?

Hello everyone.

In epics 3.16 I see a couple of .pc files are generated and installed:

./lib/pkgconfig/epics-base-linux-x86_64.pc
./lib/pkgconfig/epics-base.pc

Nonetheless, when using pkgconfig to build/link against Epics, needed  -lca -ldbCore -lCom  are missing from the command line.

Looking at the "Libs:" line at the bottom of epics-base-linux-x86_64.pc, I see they are actually missing. I added them manually and the build works.

Am I missing something or is it a bug?


Thanks.
