[wxCL-devel] Re: wxc patches for linux

[Paul V. <pa...@ca...>]

Using the 'nm' command under linux you can see which items are available in
a shared library. Running this on libwxc.so tells me that
wxEVENT_GRID_EDITOR_CREATED is available in the library, so I guess the
declarations worked correctly. As far as I am aware you don't need to do
anything special to export symbols. This is definately the case with
functions. To export something in the so file, however, it does have to be
mentioned in the link list (as you can see from my last patch).

Hope that answers the question.
