[Qt-interest] LGPL and static linking

[Bastian Bense]

I guess the .a format is, unlike shared libraries, not compatible with every
linker. So the user would need the exact version of the toolchain to be 100%
sure that re-linking will go smooth.

Why not simply provide the user two download options when downloading your
application (except, of course, for those cases where it is technically
impossible): a dynamic version (possibly hidden somewhere between the links
on the download page), and the static variant. So if he/she wants the
dynamic version and swap some DLLs, they can do it with the dynamic build,
otherwise they can enjoy the static build with the smaller file size and so
on...
