I don't have an angry blog post about the size of cross-platform libraries.
Instead, I took the (longer) time to hand-tune Qt source and qconfig.h. My cross-platform desktop builds are under 2MB in a single executable, which appears to be something the OP wanted in the first place.
Oh, I think I misunderstood your original sentence. I thought you were saying there's an angry post that needs to be written about how to make a Qt app smaller by statically compiling the app and stripping the libraries. I was saying I would like to read the post detailing how.
But, now that I've thought about it for a few minutes, it does sound pretty straight forward. Unless Qt makes it difficult for some reason?
No, Qt doesn't make it difficult. We just live in a different era where it's more convenient to complain about frameworks than to dig in to the source/config files and modify them to suit your needs.
It's a Stack Overflow world, baby, we just live in it.
