QUESTION
I'm trying to build our application using Qt 5.13.0 installed via Conan/Artifactory. We run our own Artifactory server and the Qt version there is self-build (and statically linked) in our CI solution. We use the Conan recipe for Qt written by the bincrafters, slightly modified to apply some patches for known Qt bugs and set some flags for building properly on Android and WebAssembly.
When trying to build the application, the linker fails to find the necessary dependencies for Qt itself because it tries to look them up in the home folder of the user who build the Qt package, not the user who's running the build.
Here's an excerpt from the build log, showing the attempt at linking all previously compiled object files together:
...ANSWER
Answered 2019-Sep-17 at 11:00Indeed, when building qt, all paths to dependencies are hardcoded in configurations files (mkspecs\modules\qt_lib_*.pri).
I assume you are building your application with qmake, because you use static qt, and static qt is incompatible with cmake. One thing you could try is to pass the full path to harfbuzz lib to qmake by adding argument QMAKE_LIBS_HARFBUZZ=/home/kaupes/.conan/data/harfbuzz/2.4.0/bje/stable/package/c68551ae35bf5d62e66263379d58a38416eb84a9/lib/libharfbuzz.a
to your qmake invocation.
Edit: it seems to be a knwonw behaviour of qt >= 5.12.1 : https://bugreports.qt.io/browse/QTBUG-72903. This feature has been reverted in 5.14.x and 5.15.x with https://github.com/qt/qtbase/commit/9864d2c6f3b628ca9f07a56b197e77bd43931cca

ANSWER
Answered 2018-Aug-13 at 05:20You should run configure
from top level of Qt sources and not from qtbase. In other words, you are giving top level configure options to qtbase configure which doesn't recognize them.
QUESTION
I'm using doxygen to document my Qt project. The external links to Qt with tag files are working good. But one link goes wrong.
My settings from doxygen include the "Public Member Functions inherited from " e.g. "Public Member Functions inherited from QObject" It is a dynamic title, that opens and show all public member functions. All links OK, but the link in the dynamic title is wrong.
Does anybody know how to fix this?
melogo.h
...ANSWER
Answered 2018-Jul-26 at 09:06Problem here is that doxygen generates the following HTML code:
Public Member Functions inherited from
instead of:
Public Member Functions inherited from
or:
Public Member Functions inherited from
This is due to the setting of EXT_LINKS_IN_WINDOW
, setting this tag to NO
generates valid links, but results are in the same window.
Solution: I've just pushed a proposed patch to github (pull request 6394, https://github.com/doxygen/doxygen/pull/6394 : Wrong link generated for inherited members when tag files are used.
EDIT 26 July, 2018: code has been inetgerated in master on github.

I am trying to write a desktop application using Python on backend, QML on frontend and scxml for creating state machine. I am using PySide2.

with State machine.
