Returning a QString to a QLibrary

[johnmauer]

I am using a shared library and load it using QLibrary. That requires that the functions be exported with extern "C". However, the function

extern "C" QString objectName(long type);
gets a compiler warning

'objectName' has C-linkage specified, but returns UDT 'QString' which is incompatible with C
Is there a way to export a QString return from a shared library? I would prefer not defeating a really good class like QString.

It is because of 'extern "C"'. Why do you need this extern C? As the error says you can't use QString as it is not compatible with C which is totally right as QString is a class.

simple: you have to use char* and conversions like QString::toUtf8

Yes, I've used the dual conversion already. I was just hoping that there was a better to export it; QLibrary could have been written to resolve the transformation. Thanks
