\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.io}
{Qt Project Bug Tracker}.
\section1 General Issues
\list
\li 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.
\li \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.
\li 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:
\list
\li \l{http://bugs.launchpad.net/ubuntu/+source/kdeutils/+bug/662005}
{Ubuntu bug 662005}
\li \l{https://bugreports.qt.io/browse/QTBUG-12025}
{QTBUG-12025}
\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
\li Code completion does not support typedefs for nested classes.
\endlist
\section1 Projects Issues
\list
\li 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.
\li If error messages displayed in the \uicontrol {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}.
\endlist
\section1 Debugging Issues
\list
\li When debugging executables created by the GNU Compiler version 4.5.0
(all platforms), some data types will not be displayed in the
\uicontrol{Locals and Expressions} view due to missing debug information.
\li 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)}).
\li GDB may take long to load debugging symbols, especially from large
libraries.
\li Setting breakpoints in code that is compiled into the binary more
than once does not work.
\li 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.
\li Setting breakpoints in files will fail when using LLDB if the file path
contains symbolic links.
\li 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
\l{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44731}
{GCC Bugzilla - Bug 44731}.
\endlist
\section1 Design Mode Issues
\list
\li The Design mode uses a QML emulation layer (QML Puppet) to render and preview
images and to collect data. Executing C++ code might cause the QML
emulation layer to crash. If it crashes, an error message is displayed and
you can continue editing the QML file in the code editor.
