Visual C++ compiler - moc generation

[leoalvesmachado]

Hi everyone.

I'm using QT Creator and the microsoft compiler in a project. However, I'm getting now some compiler errors (linker) due to some classes (Q_OBJECT) that I've added. I believe it is happening because there are .mocs to be generated and I believe the compiler is not generating them. Here are the error messares:

HpQCarouselEnvelope.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall Hp::Psg::HpQCarouselEnvelope::metaObject(void)const " (?metaObject@HpQCarouselEnvelope@Psg@Hp@@UBEPBUQMetaObject@@XZ)

Is there anyone here that could help me, maybe a link teaching me how to force moc generation...

Do you use the Qt VS addin? That normally handles all the MOC stuff for you.

Hi, you can add the moc call manually:
right-click the header of you class -> Properties -> Custom Build Step; add your moc call. Don't forget to add the generated moc_<classname>.cpp to your project.

But sometimes it helps to remove the class from the project once and add it again, the VS Addin will add the necessary steps for you.
