Problems with wxStyledTextCtrl etc. on Xubuntu 14.04

[imalipusram]

Dear Experts,

Serious trouble to get a simple hello world example working on Xubuntu 14.04 LTE Trusty. I suppose some missing libraries, as the errors occur in the code generated by wxCrafter.

I followed the instructions on codelite.org for installing wxWidgets. When I remove the wxStyledTextCtrl, the code compiles. Similar error messages show up with eg. wxRichTxtCtrl

wxcrafter.h contains the line
#include <wx/stc/stc.h>

These are (probably corresponding) libraries installed on my system:

Any ideas what's missing / what could be wrong?

The error messages are (full context at the end of the post)

I'm trying to teach myself C++ with a real world application and am still bloody wet behind my ears, so please excuse my ignorance.

Thanks for your help!

Its simple: you need to add stc to the linker settings.
Right click on your project and select -> Settings->Common Settings->Linker

Under the 'Linker Options'
change this line:

Code: Select all

$(shell wx-config --debug=yes --libs --unicode=yes)

to

Code: Select all

$(shell wx-config --debug=yes --libs std,stc,richtext --unicode=yes)

All the wxStyledTextCtrl is placed in a different wxWidgets library 'stc'
The --libs flag allows you specify which components of wxWidgets you are interested. By default, wxCrafter only uses the 'default' one

Dear eranif,

your suggestion is highly appreciated. Thanks!

(it works, of course)
