[Qgis-developer] Re: VS 2008 link errors for QMetaObkects references

[G. Allegri]

Somewhere I've read that this problem can be related to missing *.moc files.
The ones from the plugin I'm testing get compiled, but now I wonder if I'm
following the corect steps to link things together...

1 - I've set up a project for VS 2008, setting also the CORE_EXPORT and
GUI_EXPORT definitions.
2 - I've set the various include and lib folders and dependencies.
3 - it compiles everything, but link fails

I'm not expert with build systems, and I wonder wether this process is ok to
build a qgis plugin, or it's necessary to set the project inside the global
qgis build project to make it work. I thought that having the *.lib and the
headers from qgis would have been enough... Am I wrong?

I would appreciate your help. I'm right moving my first steps in the C++
environment...

thanks again,
Giovanni
