>Description:
A lot of ports are currently using $(INSTALL_LIB) macro to install static libraries (*.a files), presumably because the name hints at installing any kind of library.
However stripping breaks static libraries, since they are only an archives of object files not yet linked.
I detailed my analysis in PR ports/188993, which was the first port I encountered with the problem. I later discovered that there are a lot of them affected. I guess the problem does not manifests often, since static linking is seldom used.
Currently, the porter's handbook doesn't say anything about static libraries. The attached patch adds a specific note about them, and distinguish them from shared libraries.
>How-To-Repeat:
Run
grep -r 'INSTALL_LIB.*\.a' /usr/ports
and see the amount of matches
>Fix:
Hopefully patching the documentation will help porters install static libraries correctly in the future.
