Qt5 development primer
For anybody wanting to contribute to Qt5 I have started a wiki article [developer.qt.nokia.com] on how to go about getting the code for the modularised Qt5 and building it.
Please feel free to edit for other platforms or as things change during development.
Hi, I took the liberty to link to this thread from the wiki page :) I’d like to suggest a couple of changes, but on the other side do not want to start an edit war …
Don’t advocate the use of “./qtrepotools/bin/qt5_tool -p” . It’ll check out the master branches of every repo, which more likely than not break compilation . People who really want to live on the bleeding edge will find out how to achieve that … There should be no further steps necessary (no git remote rm gerrit, no special webkit/v8 handling). It’s IMO a high priority bug if that doesn’t succeed, so don’t advocate workarounds!
Along the same line, a way to update Qt5 repo isn’t qt5_tool -p, but git pull && git submodule update —recursive!
Hi! Please feel free to edit the wiki article as to the latest recommendations. I put the basic instructions up a while ago now so I am not surprised if much has changed. The usage of qt5_tool -p came from a troll on #qt-labs at the time.
A quick question, if we should not use qt5_tool -p then why does it exist?
Others have added the gerrit-related stuff and other bits and pieces.
Could you add a brief not on how to live on the bleeding edge then please? This is supposed to be an article to help people do so so that they can contribute back under Open Governance.
Many thanks for any input you can give.
Okay. The thing is that now Qt is modularized, every module moves at it’s own speed, but there are of course dependencies. E.g. a recent change in qtbase might break qtdeclarative and so on … There’s no way we can ensure that all master branches at a time work with each other (also due to the CI system). Therefore the qt5.git repo contains a list of ‘known’ SHA’s from every module that are known to work together. It’s of course not bleeding edge, but a good baseline to start with.
I’ll do the changes now.
I have a problem compiling modules other than qtbase even when following these instructions
When running make I always get
Project ERROR: Cannot load qmodule.pri!
when trying to build qtsvg and qtxmlpatterns.
Could the problem be that I am building in a different directory? Source is in ~/devel/qt5 and build dir is ~/devel/build/qt5
On mac 10.6.8, I have problems building this. The linker complains about an nonexistent “OpenGl” library. After replacing with “OpenGL” (notice capital L) in the offending files* this issue resolves.
Unfortunately QtQuick2.0 examples don’t work. For some reason importing folders from QML files is not working as it should. qmlscene doesnt recognize the imported folders (despite the fact that they are there at the same level as the invoking qml file). I keep getting:
…/somefile.qml: “SomeFolder”: No such directory
(*) among them:
./qtbase/src/platformsupport/cglconvenience/cglconvenience.pri: LIBS += -framework Cocoa -framework OpenGl
