3.0.x versions compatibility

[Fulvio Senore]

I have read that there is binary compatibility among 3.0.x versions.

Does it mean that wxWidgets include files do not change with new
versions, except for possibly adding new definitions (for example new
classes)?

I statically link a couple of wxCode projects in a large program. If I
compile the wxCode library files with 3.0.1 can I use those libraries
with 3.0.2 or do I need to rebuild the libraries with 3.0.2?

Thanks in advance.

Correct, as long as it's in the 3.0.x series.

This is only relevant with dynamically linked libraries. Statically
linking in the new version implies that you are rebuilding a new
executable.

Sorry if I do not understand, or maybe I have not been clear enough.
When I build a wxCode library I must compile it together with a version
of wxWidgets. So at the moment I have built wxPdfDocument and wxEmail
against wxWidgets 3.0.1 and I have created two .lib (or .a) files. Then
I link those files with my program, compiled with wxWidgets 3.0.1.

If I update to wxWigets 3.0.2 and I compile my program with it, can I
safely link it with the wxCode libraries created previously with 3.0.1
or must I rebuild also the wxCode libraries compiling them with 3.0.2?

It looks like I can use the older libraries, but it would be nice to be
sure. Not having to rebuild the libraries under three OSes would save me
some time.

Thanks in advance.

Ah, I see. As long as you're still linking wxWidgets itself
dynamically, I'm pretty sure this works fine as well, but maybe
someone else knows better.
