[solved] My app crashed after using macdeployqt (Qt5.2 RC 1)
-
no, but the following code has been added to main.cpp already,
@int main(int argc, char *argv[])
{QApplication a(argc, argv); QDir dir(QCoreApplication::applicationDirPath()); qDebug()<<dir.absolutePath(); dir.cdUp(); qDebug()<<dir.absolutePath(); dir.cd("PlugIns"); qDebug()<<dir.absolutePath(); QApplication::setLibraryPaths(QStringList(dir.absolutePath())); qDebug()<<QCoreApplication::libraryPaths();@
and the relevant application output
@"/Users/gint_develop/Documents/maserati/branches/build-OneChecker-Desktop_Qt_5_2_0_clang_64bit-Release/OneChecker/1Checker.app/Contents/MacOS"
"/Users/gint_develop/Documents/maserati/branches/build-OneChecker-Desktop_Qt_5_2_0_clang_64bit-Release/OneChecker/1Checker.app/Contents"
"/Users/gint_develop/Documents/maserati/branches/build-OneChecker-Desktop_Qt_5_2_0_clang_64bit-Release/OneChecker/1Checker.app/Contents/PlugIns"
("/Users/gint_develop/Documents/maserati/branches/build-OneChecker-Desktop_Qt_5_2_0_clang_64bit-Release/OneChecker/1Checker.app/Contents/PlugIns") @ -
Also, Here is another important clue,
@This application failed to start because it could not find or load the Qt platform plugin "cocoa".@
maybe the reference pointing to the platform plugin in the bundle is broken, and QCoreApplication::libraryPaths() is not used to search for platform plugins , as" what he said":https://bugreports.qt-project.org/browse/QTBUG-29503 -
Can you build Qt from sources and use this one to create your application ? I didn't have that problem with a current git build
-
Actually,I got stuck when I tried to build Qt from source. Particularly, they were some errors about webkit...I am trying to solve it.
-
I followed these steps again:
1)git clone git://gitorious.org/qt/qt5.git qt5
2) cd qt5
3) ./init-repository
4) ./qtrepotools/bin/qt5_tool -p
5) .........but got this at step 4,
Entering 'qtactiveqt'
Fetching origin
Fetching gerrit
ssh: connect to host codereview.qt-project.org port 22: Operation timed out
fatal: Could not read from remote repository.Please make sure you have the correct access rights
and the repository exists.

seems I'm not alone. someone has posted it "Here":https://bugreports.qt-project.org/browse/QTBUG-21139 ,but no reply.
-
I've downloaded qt5.2 source code and built it successfully. but it makes no difference.

Do you mean, the source tar.gz or from git ?
-
The former, the problem is still there when I try to git.

Provisional measures :
adding the following code to main.cpp (before QApplication a(argc, argv));I think the path of loading plugins has to be loaded before running QApplication a(argc, argv);
@int main(int argc, char *argv[])
{
QString path = QString(argv[0]);
QString end = path.split("/").last();
path.remove(path.length() - end.length(), end.length());
QDir dir(path);
dir.cdUp();
dir.cd("PlugIns");
QApplication::setLibraryPaths(QStringList(dir.absolutePath()));QApplication a(argc, argv);
......

Wasn't that part of a bug report ?
