"error: aggregate ‘QDataStream stream’ has incomplete type..."

[jabowery]

I'm getting compile errors under Debian (Stretch) and Ubuntu 18.04 systems:

I had the same problem on Ubuntu 20.04. The compilations works after this change:

Hi @jabowery, now that @mimecorg merged PR #6 , can we close this issue?

@jabowery could you retry building the new tag v0.4.8.1 ?
