To correct the "undefined reference to IID_IUnknown" error, add -luuid in the project's linker options.
The "WinMain" error comes from one of two reasons:
a) you 're building a console project but have it setup as a GUI one in project's properties, or
b) you need to add -lmingw32 in the project's linker options

HTH,

Um, actually, we have been talking about this for a couple days, through other forum channels. I already have the -luuid in project linker options, and I already changed the project properties to reflect that it's a console app. Just for yucks, I now tried the -lmingw32 project linker option. All to no avail...

mandrav:
OK, go to global compiler options and change the logging level for GCC to "Full". Rebuild your project and post here the full build log. Maybe then we can see what's going on...

Thanks, I came to the sad realization the other day, that I don't speak MAKE, an essential dialect for a serious code joc. As I said, probably due to coddling by MSomething over the years...

Have you messed with the advanced compiler options? I 'm asking 'cause there is "-c" missing from the command line. Just before "component.cpp"...
Go to "Settings/Configure plugins/Compiler", switch to the "Other" tab, click "Advanced options..." and post here the command for "Compile single file to object file". The GCC command is "$compiler $options $includes -c $file -o $object"...

Yiannis.
