I'm testing the FreeCAD build and discovered that the help menu returns the
error message: "Unable to launch Qt Assistant
(/opt/local/bin/Assistant.app/Contents/MacOS/Assistant)". Launching Qt
Assistant is done in the function startAssistant() which is found in
src/Gui/Assistant.cpp. The following lines get the name of the executable and
the doc path:
#ifdef Q_OS_WIN
QString app;
app = QDir::toNativeSeparators(QString::fromUtf8
(App::GetApplication().GetHomePath()) + QLatin1String("bin/"));
#else
QString app = QLibraryInfo::location(QLibraryInfo::BinariesPath) +
QDir::separator();
#endif
#if !defined(Q_OS_MAC)
app += QLatin1String("assistant");
#else
app += QLatin1String("Assistant.app/Contents/MacOS/Assistant");
#endif
QString exe =
QString::fromUtf8(App::GetApplication().getExecutableName());
QString doc = QString::fromUtf8(App::Application::getHelpDir().c_str());
QString qhc = doc + exe.toLower() + QLatin1String(".qhc");
I'm not that familiar with c++ but I believe
'QLibraryInfo::location(QLibraryInfo::BinariesPath) + QDir::separator()' is
setting the variable 'app' to /opt/local/bin. This line needs to be patched so
that it finds /Applications/Macports/Qt4. How is a string used as a file path
In c++?
