Print Page - Cannot build wxWidgets 2.8.0 project using wxRichText

Hi everyone,

I'm experiencing some problems with C::B and wxWidgets library.
Everything is in the title: I cannot build wxWidgets projects using richtext and/or xml library. I'm sure the problem comes from my C::B's configuration, cause I even can't build wx's richtext sample, which can be build by a MingW make command.
When I try to build the richtext sample with C::B (using the unofficial modified wxWidgets wizard and including every libraries), I got the following error messages:

Could anyone please help me ?

Libraries order?

Try moving libwxmsw28ud_richtext.a before libwxmsw28ud.a (or whatever it be called in your system).

Wonderful, It works like a charm!

How can you explain the importance of librairies order? Besides, I find quite unintuitive to put base librairies after high-level ones... don't you ?

Anyway, should I consider this like a bug and inform the unofficial wizard's development team ?

Thanks a lot !

Let's say it this way: if library A needs something from library B, that something will be "searched" in the following libraries, not the previous ones, so you need to put A first, then B. While this may not be an accurate definition, the basic idea is there.

In your case, wxmsw_richtext needs something from wxmsw, that's why wxmsw must go after wxmsw_richtext.

If that's a wizard's fault, inform it.

Understood! :)

The library inclusion was generated by the wizard, so I'll inform the team about it.

Thank you very much!

The fact that linking order matters is nobody's fault. It's just how ld (gcc's linker) works. But if the project was generated by a wizard then that wizard could be updated to use the correct linking order ;).

I've updated the build order. I'll post it after some more tests.
