+1 on this i am in the process of porting my legacy project to Qt and am afraid that i’ve made the wrong choice. i’m just one guy and i bet my whole business on the availability of what i need from Qt under LGPL
i’m already using a third party HTTP server so i’m not affected by this but it’s a worrying sign. I too agree that the HTTP server really should be LGPL. What’s going to happen? It’s taken me over a year’s worth of work to get this far with Qt and i’m only half done. did i make the wrong choice? -dave > On Aug 14, 2019, at 9:18 AM, Benjamin TERRIER <b.terr...@gmail.com> wrote: > > Hi everyone, > > Since we are talking about the future of Qt these days, I would like > to know The Qt Company free software policy with Qt. > > Today, most of Qt modules are released under 3 free software licenses: LGPLv3, > GPLv2 and GPLv3.
