Обсуждение: Strange error message when linking
Hi, I'm still working on a ctlColourPicker widget, our custom wxColourPickerCtrl to work around issues found on Mac OS X by Dave. I was obviously wrong when I said that coding this widget would be simple :-/ The patch attached is my current work. I'm pretty ashamed of it, but can't find a way to fix my linking issue. Here is the error I got at the linking step: pgAdmin3.o: In function `ctlColourPickerXmlHandler': /home/guillaume/freeprojects/git.pgadmin/pgadmin/../pgadmin/include/ctl/xh_ctlcolourpicker.h:25: undefined reference to `vtable for ctlColourPickerXmlHandler' collect2: ld returned 1 exit status I have absolutely no idea what this could mean. Search engines didn't help me on this. I don't know what to do. If you have any idea, I welcome them. If I don't find any way to fix this before the end of the week, I think I'll fix the first issue another way: replacing wxColourPickerCtrl with wxBitmapButton for each control (which means duplicated code, but much simpler work). Simpler work means quicker work, so more time to code new interesting 9.0 features. And I'll get back to this widget for next dev cycle. But I would definitely prefer having a solution to my linking issue. -- Guillaume. http://www.postgresqlfr.org http://dalibo.com

Hi Guillaume,
Very small mistake. (I saw this error earlier.)
You forget to add "$(srcdir)/ctl/xh_ctlcolourpicker.cpp" in "pgadmin/ctl/module.mk" file.
Please find the attached patch.
