Ah indeed. It worked! To recap: I have added the following to MyApp PRO file: PRE_TARGETDEPS += $$PWD/../staticlib/debug/staticlib.lib
It’s a bit pity that PRE_TARGETDEPS takes the absolute path to the file rather than simply the target name (thus resolving the path on its own depending on OS and naming conventions) Thank you Thiago and Elivs for the help! -----Original Message----- From: Elvis Stansvik [mailto:elvst...@gmail.com] Sent: Friday, June 16, 2017 10:15 PM To: Enmaniac Software Cc: interest@qt-project.org Interest Subject: Re: [Interest] Automatic relink of executable after change in dependant static library 2017-06-16 21:08 GMT+02:00 Enmaniac Software <enmaniac.softw...@gmail.com>: > Hi all, > > > > I hope I am posting it in the right place.
