\title Known Issues
\brief Known issues in \QC version \qtcversion.
The \QC development team is aware of the issues described here, and
therefore, you do not need to report them in the \l{https://bugreports.qt.io}
{Qt Project Bug Tracker}.
For a list of fixed issues and added features, go to \uicontrol Help >
\uicontrol {Change Log}.
\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.
\li When developing on Linux, the \key {Ctrl+Shift+U} keyboard shortcut
might not work because it conflicts with a shortcut of the
Intelligent Input Bus (ibus). You can change either the shortcut in
\QC or the conflicting shortcut in ibus.
To set another \l {Keyboard Shortcuts}{keyboard shortcut}
in \QC, select \preferences >
\uicontrol Environment > \uicontrol Keyboard.
To change the ibus shortcut, enter the following command on the
command line to start ibus setup:
\badcode
ibus-setup
\endcode
Then, change the unicode code point shortcut in the \uicontrol Emoji
tab to something else than \key {<Control><Shift>u}.
\endlist
\section1 Projects Issues
\list
\li Paths or file names that have 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 \l {Compile Output} have
paths where slashes are missing (for example, C:QtSDK),
check your PATH variable. For more information, see
\l{Troubleshoot 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 \uicontrol Expressions views 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 \c {--bind mount} option.
\li Setting breakpoints in files will fail when using LLDB if the file path
has 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}.
