[fpc-pascal] linking to dll still fails

[Marc Santhoff]

Hi again,

I have more questions on linking. What can prevent dynamic linking from
being possible? Like in the following snippet from fpcdebug.txt:

00008000:Searching file D:\FPC\2.2.0\BIN\I386-WIN32\libhdf5.dll.a... not found

Is there any documentation on this topic?
Or maybe some hints how the reason that stops dynamic linking can be
found?

I'm amazed that this is an issue, I would never expect problems on such
matters ...
