Patching?
The error is simple: can not find the library. ld can not tell much
more, except maybe where it has searched, and what .o file or link.res
has asked for the library.
Maybe a quickfix item can be added to extend the message with that
information. Just like the IDE is doing for "can not find unit"
messages.
It can not give the information how to install the needed library,
because there are too many possibilities. Maybe a link to a page
about linker errors with some explanations and examples
can be given.
Or the lpk could provide a fpdoc topic about link errors and the IDE
could automatically show that.
