I have a problem with QFileDialog. I used this code:
fileDialog = new QFileDialog(this);
fileDialog->setFileMode(QFileDialog::Directory);
fileDialog->setReadOnly(true);
if (fileDialog->exec()){
ui->FilePath->setText(fileDialog->directoryUrl().toString());
}
In application out, it told me this:
shell\comdlg32\fileopensave.cpp(9456)\comdlg32.dll!00007FF9A3A2260A:
(caller: 00007FF9A3A2A866) ReturnHrPreRelease tid(2110) 80070490
Élément introuvable.
CallContext:[\PickerModalLoop\InitDialog\FileDialogInitEnterpriseData]
I use Qt creator 3.5.0 and Qt5.5.0 on Windows 10.
Does anybody have a solution for this?
This issue has been answered in the following thread :
How to debug …\comdlg32\fileopensave.cpp
TLDR : not an issue. message is an extra debug message from win10 api.

I have started to face this problem. While trying to connect, I am facing an error stating that my traffic-manager version is 2.1.5 and it should be at least 2.4.5.
"telepresence connect" command checks for new versions and modifies it if there is any new version exists. So I am thinking that started to create a problem. Because I was using it as normal.
When I check the connector.log file these two lines create the problem.
connector/session : Existing Traffic Manager 2.6.5 not owned by cli or does not need upgrade, will not modify
connector/session : failed to connect to root daemon: rpc error: code = Unknown desc = unsupported traffic-manager version 2.1.5. Minimum supported version is 2.4.5
So somehow I have two versions now while checking for the update it hits 2.6.5 but while trying to run it tries with 2.1.5. Trying to uninstall telepresence but it also faces the same problem and I couldn't locate and delete traffic-manager 2.1.5. My OS is Windows 11.
Because of that, I am kind of blocked with my tests. Any help will be well appreciated. Thanks!
After asking the question, a new version arrived, if anyone encountered this problem, please update telepresence to 2.6.6. It is fixed now.
I have been created a build with Buildroot. Also did it everthing on this comment -> https://www.raspberrypi.org/forums/viewtopic.php?t=263418#p1614833
Did my research, and dozens of trials, and I get nothing.
My config is:
Rpi4-64, QT5-Qml, Mesa v3d-vc4, opengl es 2.0
When I try to run my qt qml application on this build, I'm getting this error:
QStandardPaths: wrong permission on runtime directory /usr/bin/, 7755 instead of 7700
drmModeGetResources failed (Operation not supported)
no screens available, assuming 24 -bit color
Cannot create window: no screens available.
Summary : I need to run my qt5 qml application on Rpi 4 with hw accelerated.
I found the solution.
I think the Rpi4 with eglfs using default card for card0, and this is not work. Need to force using card1 for eglfs.
Create a file "eglfs.json" with the following content:
{ "device": "/dev/dri/card1" }
export QT_QPA_EGLFS_KMS_CONFIG=/wherever/is/the/file/eglfs.json
and run your qt app!
Also my qt5 qml program is not showing fonts or text on rpi4 buildroot system. Coping /usr/share/fonts/your_program_fonts worked for me.
I have installed spark with 2.0 on CDH5.10 By following the link https://www.cloudera.com/documentation/spark2/latest/topics/spark2_installing.html
after all configuration when I hit spark2-submit --version it gives me correct version which is 2.0
however when I submit a spark job . First it says
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataInputStream
This is clearly indicating that hadoop libs are not in classpath. My question is it something wrong with my installation of spark 2. ? also once we add jars with sparkExtralibCLasspath for driver and core then it says SPARK_HADOOP_CONF Is not set.
How can I verify my installation is correct ?
I am also trying to understand where are my spark2 conf dirs
I saw few previous question on stackoverflow like https://community.cloudera.com/t5/Cloudera-Manager-Installation/CHD-5-7-spark-shell-java-lang-ClassNotFoundException-org-apache/td-p/42209 and NoClassDefFoundError com.apache.hadoop.fs.FSDataInputStream when execute spark-shell but this doesnt help
I am using spark2-shell and spark2-submit command
some more investigation with https://community.cloudera.com/t5/Cloudera-Manager-Installation/CDH-5-5-pyspark-java-lang-NoClassDefFoundError-org-apache-hadoop/td-p/34424 shows might be If I can correctly set SPARK_EXTRA_LIB_PATH for spark2 then I can fix this issue. can somebody guide me please. Thanks
I tried to build qt 5.2.1 (opensource.zip) on a Windows 7 64 bit machine with Visual Studio 2005 Professional while having ActivePerl etc. installed. I used the Visual Studio 2005 Command prompt with the following line for configure:
configure -platform win32-msvc2005 -xplatform wince60standard-armv4i-msvc2005 -opensource -nomake examples
which ends up in the following output after about 2 min.:
…
qglobal.cpp
qmalloc.cpp
qlibraryinfo.cpp
qnumeric.cpp
qlogging.cpp
D:\qt-source5.2.1\qtbase\src\corelib\global\qlogging.cpp(96) : error C3861: “GetConsoleWindow”: identifier not found.
Code will be generated…
NMAKE : fatal error U1077: ““C:\Program Files (x86)\Microsoft Visual Studio 8\VC\BIN\cl.EXE”“: return code “0×2”
Stop.
Building qmake failed, return code 2
I also tried to do just a simple:,
configure
within Visual Studio 2005 Command Prompt -> Ends up in the same error.
Does anybody know what wents wrong here? Am i doing something totally wrong or missing something?
I also posted this to the qt Forums of a thread created by a user who had a similar problem -> http://qt-project.org/forums/viewthread/36177/
But nobody replied there.
EDIT: Today i updated my question in QT forums. See -> http://qt-project.org/forums/viewthread/36177/ I modified the problem file qtbase\src\corelib\global\qlogging.h and added the following on top of it:
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0×0500
#endif
I found this solution while searching for “getConsoleWindow” problems. The reference is written down as remark here -> http://msdn.microsoft.com/en-us/library/windows/desktop/ms683175(v=vs.85).aspx
After this my configure runs fine without any problems. But now I expected the following error after calling nmake. After nmake runs ~30 mins i got this output:
d:\readonly\qtsrc\qtbase\include\qtcore\../../src/corelib/tools/qvector.h(666) : error
C2244: 'QVector<T>::erase' : unable to match function definition to an existing declaration definition 'QVector<T>::iterator QVector<T>::erase(QTypedArrayData<T>::iterator,QTypedArrayData<T>::iterator)'
existing declarations
'QTypedArrayData<T>::iterator QVector<T>::erase(QTypedArrayData<T>::iterator)'
'QTypedArrayData<T>::iterator QVector<T>::erase(QTypedArrayData<T>::iterator,QTypedArrayData<T>::iterator)'
There are some more errors but all with QVector::insert and QVector::erase. I Googled a bit and found this post here which looks like a similar problem and is also not replied yet: http://qt-project.org/forums/viewthread/36735
I think i have to say that i compile for custom ce sdk. So i changed the qtbase\mkspecs\wince60standard-armv4i-msvc2005\qmake.conf and added additional includes and libraries there. I also use the following defines there:
DEFINES += WINCE WINDOWS WINDOWS_CE_OS _WIN32_WCE=0×600 UNDER_CE=0×600 ARM _ARM ARMV4I UNICODE UNICODE _USE_32BIT_TIME_T _CRT_SECURE_NO_DEPRECATE $$CE_ARCH _AMRV7 armv7 ARM QT_NO_CLIPBOARD QT_NO_ACCESSIBILITY QT_NO_NATIVE_GESTURES QT_NOSTANDARDSHELL_UI_MODEL
Is it so hard to compile qt 5.2.1 for ce? Should i use an older version of qt (i need at least qt5 for JSON handling)? Any suggestions regarding this issue here?
Use thirdpaty library for JSON. Visual Studio 2005 is too old compiler. For example - jsoncpp or QJson.
OSX: 10.6.8
Xcode: 4.0.2
Phonegap: 1.4.1.js or Cardova-1.7.0
Following simple HiWorld example http://phonegap.com/start produces the following error from:
AppDelegate.m:
self.viewCOntroller = [[[MainViewCOntroller alloc] init] autorelease];
ERROR:
Thread 1: Program received signal: "EXC_BAD_ACCESS"
EDIT: I was using the ipad 3.2 Simulator, as soon as I changed it to iphone 4.0 or above the problem went away.
This is (in my opinion), the most common error in iOs development.
The error means that you're trying to access something that has already been released.
You may be trying to access the viewController sometime after having already released it.
Remove autorelease and see what happens.
