[squeak-dev] Linking a plugin with a library

Hi all,

I'd appreciate some help with building a plugin for Windows. The
plugin generates and compiles fine; the problem is at the link stage.
I don't know how to configure the make so that it links the plugin
with a library that it requires. I've searched the web but I haven't
been able to find anything that covers this specifically. Any pointers
you can give me would be welcomed.

Thanks,

--John

You need to add an option to linker in your plugin makefile
like:
-lmyimportlibrary

and to generate import library, please read this page:
http://oldwiki.mingw.org/index.php/CreateImportLibraries

i hope it helps.

This page talks about creating a .def file but doesn't say where the
file goes. Thanks again,

That's what I'd like to do but I don't have a makefile for my plugin,
or at least, I haven't created one. It just seems to get made
automatically. What would be in such a makefile, and where would I put
it? The default makefile (assuming that's what's being used) is mostly
doing what I want except for the specification of the extra library.

Sorry to be such a dunce!

Thanks again,

It does,

[[
Once you've created the def-File (see above) you'll issue

    dlltool -d somedll.def -l libsomedll.a

That's it. The resulting file libsomedll.a should satisfy the linker.
]]

it creating an import library (libsomedll.a) which you can link with
your plugin (using -l linker option) so , that final .exe file will
look for a .dll

Just add a 'makefile' file to the directory where platform files of
plugin are located
(platforms/win32/plugins/YourPluginName/makefile)


here an example of makefile, for freetype plugin:
---------------
include ../../Makefile.plugin

# This seems broken, but in the generated FT2Plugin.c there is an
# include<tttables.h> which should be include<freetype/tttables.h>
# so we simply add it to the include path. Eeek.
INCLUDES+= -I$(WIN32DIR)/freetype

# Add the freetype libs to the build
EXTRALIBS=$(WIN32DIR)/freetype.a
-----------------

Thanks Igor, that was exactly the information I needed.
