I am talking about situation 3: We have built and installed it locally with `make install`, and have removed the installation directory (or at least points the configure argument to the installed directory). In this case, you will not have a .libs directory. I still don't see why it would be such big deal to check for the required files in both the directory directly, and then, if it is not found, check in a `.libs` directory? That's all I request, to increase the likelyhood that this works with many different kinds of setup. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15138#issuecomment-1768718738
