#NetBSD people! I need some help.

I'm trying to update the port of an old piece of software (#plptools), but I'm having issues with linking it to readline.

It's detecting libedit first, even though FSF readline is installed. The following does nothing:

CPPFLAGS="-I/usr/pkg/include/readline/" LDFLAGS="-L/usr/pkg/lib/" ./configure

Adding LIBS="-lreadline" throws an error early on in ./configure, saying that it can't find libreadline.so.8.

Do you have any advice at all?

The GitHub issue is here: https://github.com/plptools/plptools/issues/22#issuecomment-2954149613

@penguin42 @thelastpsion works on netbsd. adding /usr/pkg/lib to /etc/ld.so.conf should also work but strange /usr/pkg/lib is not picked up by default... setting rpath at build time should fix this: LDFLAGS="-L/usr/pkg/lib -Wl,--rpath=/usr/pkg/lib" to configure.

@penguin42 @thelastpsion usually ./configure --prefix=/usr/pkg should take care of these things... (assuming you are making/updating a port).

@kaveman @penguin42 Both of these worked - thank you! I did have to add LIBS="-lreadline" as well (to the LDFLAGS version) to make sure that it picks readline and not libedit

And now I've got a new issue... 😅

--- plpftp-ftp.o ---

I'm out of brainpower for tonight, so this will be for another day. But thank you for helping me make some progress!

@thelastpsion Note that it's wanting constness for the first argument.

@penguin42 It just seems odd, because this error doesn't happen on the three other platforms that plptools compiles on.

EDIT: A bug has been picked up by another maintainer that's very likely related to this but just didn't show up on the other platforms. I'll check in the morning.

@thelastpsion Not obvious to me, but it's possible it's due to the BSDs having a different readline (wouldn't surprise me if they've not got the GNU version?) - but hmm that error is the wrong way around for that. I look forward to the answer 🙂
