\title Known Issues
|
|
|
|
|
|
|
|
|
|
|
|
This section lists known issues in \QC version \qtcversion. The development
|
|
|
|
|
|
team is aware of them, and therefore, you do not need to report them as
|
|
|
|
|
|
bugs.
|
|
|
|
|
|
|
|
|
|
|
|
For a list of fixed issues and added features, see the changelog file in
|
|
|
|
|
|
the \c{qtcreator\dist} folder or the \l{https://bugreports.qt.nokia.com}
|
|
|
|
|

{Qt Bug Tracker}.

\section1 General Issues
|
|
|
|
|
|
|
|
|
|
|
|
\list
|
|
|
|
|
|
|
|
|
|
|
|
\o If you change the Input Languages in Windows, \QC might not
|
|
|
|
|
|
respond for 30 seconds. This is a known issue in the Advanced Text
|
|
|
|
|
|
Service of Microsoft Windows.
|
|
|
|
|
|
|
|
|
|
|
|
\o \QC uses SQLite for storing some of its settings. SQLite is
|
|
|
|
|
|
known to have problems with certain NFS servers (most notably the
|
|
|
|
|
|
nfs-user-server 2.2beta), since they can lock up the application
|
|
|
|
|
|
when it tries to lock the database. If your home directory is on an
|
|
|
|
|
|
NFS share and you encounter this issue, one option would be to
|
|
|
|
|
|
switch to the nfs-kernel-server, or create a symlink so that the
|
|
|
|
|
|
settings are stored locally.
|
|
|
|
|
|

|
|
|
|
\o Qt 4.7.4 is known to contain a bug exposed by g++ 4.6 which triggers
|
|
|
|
|
|
a crash in \QC. For more information, see
|
|
|
|
|
|

|
|
|
|
\o The Okteta KDE custom widget plugin might be installed as part of
|
|
|
|
|
|
some Linux distributions. It can cause Qt Designer to crash. For
|
|
|
|
|
|
more information, see:
|
|
|

\endlist
|
|
|
|
|
|
|
|
|
|
|
|
To resolve the issue, enter the following command to remove the
|
|
|
|
|
|
package:
|
|
|
|
|
|
\code
|
|
|
|
|
|
sudo apt-get remove okteta
|
|
|
|
|
|
\endcode
|
|
|
|
|
|
Or delete the following file:
|
|
|
|
|
|
\c /usr/lib/kde4/plugins/designer/oktetadesignerplugin.so.
|
|
|
|
|
|
|
|
|
|
|
|
\endlist
|
|
|
|
|
|
|

|
|

\section1 Editing Issues
|
|
|
|
|
|
|
|
|
|
|
|
\list
|
|
|
|
|
|
|
|
|
|
|
|
\o Code completion does not support typedefs for nested classes.
|
|
|
|
|
|
|
|
|
|
|
|
\endlist
|
|
|
|
|
|
|
|
|
|
|
|
\section1 Projects Issues
|
|
|
|
|
|
|
|
|
|
|
|
\list
|
|
|
|
|
|
|
|
|
|
|
|
\o Paths or file names containing spaces or special characters
|
|
|
|
|
|
(such as colons, dollar signs, and hash marks) may cause problems.
|
|
|
|
|
|
This is because some of the tools \QC uses in the background have
|
|
|
|
|
|
restrictions on the characters allowed in file and directory names.
|
|
|
|
|
|
To be on the safe side, we recommend creating projects and project
|
|
|
|
|
|
items with names consisting of plain characters, numbers,
|
|
|
|
|
|
underscores, and hyphens.
|
|
|
|
|
|
|
|
|
|
|
|
\o Creating new CMake projects with \QC is not supported.
|
|
|
|
|
|
|
|
|
|
|
|
\if defined(qcmanual)
|
|
|
|
|
|
\o On Windows, you must create projects for Maemo 5 and Harmattan
|
|
|
|
|
|
targets on the same partition where you installed \QSDK, \QC, and
|
|
|
|
|
|
MADDE.
|
|
|
|
|
|
\endif
|
|
|
|
|
|
|
|
|
|
|
|
\o If error messages displayed in the \gui {Compile Output} pane contain
|
|
|
|
|
|
paths where slashes are missing (for example, C:QtSDK),
|
|
|
|
|
|
check your PATH variable. For more information, see
|
|
|
|
|
|
\l{Troubleshooting MinGW Compilation Errors}.
|
|
|
|
|

\section1 Debugging Issues
|
|
|
|
|
|
|
|
|
|
|
|
\list
|
|
|
|
|
|
|
|
|
|
|
|
\o Debugging large applications on Symbian devices using the Symbian^3
|
|
|
|
|
|
operating system might not work, because the on-device debugging
|
|
|
|
|
|
agent might not be able to access memory when the operating system
|
|
|
|
|
|
starts paging. This causes breakpoint handling and symbol resolution
|
|
|
|
|
|
to fail. For more information, see
|
|
|
|
|
|
\l{https://bugreports.qt.nokia.com/browse/QTCREATORBUG-2158}
|
|
|
|
|
|
{QTCREATORBUG-2158}.
|
|
|
|
|
|
|
|
|
|
|
|
As a workaround, add the following section to the application .pro
|
|
|
|
|
|
file to disable paging:
|
|
|
|
|
|
|
|
|
|
|
|
\code
|
|
|
|
|
|
debug {
|
|
|
|
|
|
MMP_RULES -= PAGED
|
|
|
|
|
|
MMP_RULES *= UNPAGED
|
|
|
|
|
|
}
|
|
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
|
|
|
|
\note You must completely clean and rebuild the project for the
|
|
|
|
|
|
setting to take effect.
|
|
|
|
|
|
|
|
|
|
|
|
\o When debugging executables created by the GNU Compiler version 4.5.0
|
|
|
|
|
|
(all platforms), some data types will not be displayed in the
|
|
|
|
|
|
\gui{Locals and Expressions} view due to missing debug information.
|
|
|
|
|
|
|
|
|
|
|
|
\o GDB on Windows may not work if the 'Embassy \reg Security Center'
|
|
|
|
|
|
software by 'Wave \reg Systems' is installed and active (causing
|
|
|
|
|
|
crashes in \c{vxvault.dll)}).
|
|
|
|
|
|
|
|
|
|
|
|
\o GDB may take long to load debugging symbols, especially from large
|
|
|
|
|
|
libraries.
|
|
|
|
|
|
|
|
|
|
|
|
\o Setting breakpoints in code that is compiled into the binary more
|
|
|
|
|
|
than once does not work.
|
|
|
|
|
|
|
|
|
|
|
|
\o Setting breakpoints in files that do not have unique absolute
|
|
|
|
|
|
paths may fail. For example, remounting parts of a file system
|
|
|
|
|
|
using the --bind mount option.
|
|
|
|
|
|
|
2011-11-09 16:38:17 +01:00
|
|
|
|
\o A regression in GCC 4.5.0 causes return value optimization to
|
|
|
|
|
|
produce inaccurate debug info that GCC applies also to
|
|
|
|
|
|
non-optimized builds. For more information, see
|

|
\list
|
|
|
|
|
|
|
|
|
|
|
|
\o \QMLD uses external processes (QML Puppet) to render and preview
|
|
|
|
|
|
images and to collect data. Executing C++ code might cause the QML
|
|
|
|
|
|
Puppet to crash. If it crashes, an error message is displayed and
|
|
|
|
|
|
you can continue editing the QML file in the code editor.
