[Interest] qmake, executable static libs...
Hi guys, I'm porting Qt 5 application to Linux and ran into a problem of linking. This application depends on two external static libs (let's say libs A and B). But this libs is in the tree of the project. And this project depends on two yet internal static libs (let's say libs C and D). Libs C and D depends on libs A and B. All static libs creates successfully. But executable can't link. I have added all 4 static libs ( A,B,C,D ) to the project of executable ( link rules, pretarget deps...) And ld says when linking executable that in static lib C there are undefined references to functions and methods from static lib A. What should I do in .pro files to solve this problem. P.S. On windows with MSVC linking is successful. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
