Custom Plugin Trouble

[wysota]

You forgot to implement the destructor for CustomPlugin.

Actually, while tinkering I realised that.
I'm still not sure why that has to be done. Is that something to do with pure virtual interfaces, therefore the compiler tries to implicitly create a destructor which it can't because the class can't be concrete?

It has to do with the fact that you explicitly declared it but didn't implement it. Being pure virtual or not has little to do with this.

Ok, I also had to inherit from QObject and specify Q_OBJECT to avoid some further conflicts.

So ... I compiled it on MacOS X but was having trouble debugging, due to the environment I have setup on the machine, so I moved it to my Windows box, but now I'm getting these errors:

Any idea how to get Qt Creator to find mt.exe? Is it possible to add environment variables to the build step via the .pro file? I'm surprised that mt.exe isn't in the path already after having installed Visual Studio.

Will go with a system wide env var if I have to.

Thanks,

Steve

So... it can find cl.exe but not mt.exe? That's hardly possible unless you don't have mt.exe at all
