I'm trying to add Coverity Scan static analysis to my Qt project but I'm not able to get the result.
I download the coverity scan build tools and use the following command line:
cov-build --dir cov-int make
Which produces the following log:
...
my build log
...
[WARNING] No files were emitted. This may be due to a problem with your configuration
or because no files were actually compiled by your build command.
Please make sure you have configured the compilers actually used in the compilation.
For more details, please look at:
/Users/martin/dev/builds/ConsoleTest01-Desktop_Qt_5_3_clang_64bit-Debug/cov-int/build-log.txt
How can I go further?
I'm using Qt 5.3.2 under MacOS 10.9.
I didn't read the docs carefully enough: https://scan.coverity.com/download?tab=cxx
I had to configure coverity first by running:
cov-configure --comptype clangcxx --compiler clang++ --template
You need to run qmake first, then you can run the cov-int command with make.
I found it easiest to run cov-int in my build- folder created by Qt-Creator.

My environment is below.
・Operating System and version:windows 10 64bit
・Compiler:C:\msys64\mingw64\bin\g++.exe
・PCL Version:1.9.1
pcl_config.h not found as below error occurred when compiled under above env..
Certainly this header file is not included.
Let me know how to solve it.

compilation terminated.
Short answer
pcl_config.h is generated via pcl_config.h.in by the cmake tool. So it seems that compilation did not finish correctly.
Longer answer
Please make sure you have compiled the relevant modules of PCL (at least pcl-core) before proceeding
You might prefer a pre-built installation from releases or distributed by a package/source manager of your choice
PCL makes heavy use of other libraries and it is best to supply the dependencies (as mentioned below) via CMake or manually via the -I and -l options. If you provide the location of pcl_config.h, the compiler will complain about Eigen next.
The build instructions are available here. TL;DR: After satisfying the dependencies (cmake, c++ compiler, boost, eigen, flann, vtk and other depending on use-case), run the following commands
cd $PCL_SOURCE_DIR
mkdir -p build; cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j8
Feel free to use any build generator (like Ninja) or change build type to Debug or RelWithDebInfo as per your needs.
I'm interested in learning about kde environment. So I read the contribution page on wiki, git cloned the kompare repo and built it. But an attempt to execute the binary gave me an error saying Could not load our KompareNavigationPart. The console showed the following error about kservice:
> ./kompare
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
kf5.kservice.services: KMimeTypeTrader: couldn't find service type "Kompare/ViewPart"
Please ensure that the .desktop file for it is installed; then run kbuildsycoca5.
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
Aborting aboutToFinish handling.
I couldn't find anything about it in the readme or the project wiki. I've installed the kde-development-meta package on arch linux. Can anyone help me get started with development on kde platform?
Short answer: Use "cmake -DCMAKE_INSTALL_PREFIX=/usr" and "make install".
Long answer: It looks like you tried to run from the build directory, but the KDE plugin loader does not look there by default. You could adjust the various path variables to additionally point to your build directory. The variables are mentioned at https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source#Set_up_the_runtime_environment
You can also use "make install" to install to a run-time directory. If you did not change the defaults of cmake via -D option, this will be "/usr/local/", and in this case you also have to adjust the various path variables to include that directory, unless your distribution already configured this for you.
I am running this build through the JWrapperApp. When ever I try and build my 86.7Mb .jar file, it gets to the step of adding the .jar file to archive then fails with a java.lang.OutOfMemoryError. I have tried only building for one OS at a time, as well as adjusting some other settings but none seem to have an effect.
I have successfully been able to build the sample-app and I know my .jar file is in working order.
I would suggest you try starting your JWrapperApp with more memory by passing the JVM option -Xmx1024m or greater to it. This entails starting the JWrapperApp packager from the commandline/shell using the following command:
java -Xmx1024m JWrapperApp.jar
On windows after running the grunt build command for creating brackets shell it gives done without errors but i dont see any .exe file generated..
What might be the problem???
Here are some possible solutions:
Are you following the full brackets-shell build instructions, including all prerequisites?
Make sure Brackets isn't running at the same time. The build will fail silently if the .exe file is currently in use (see bug).
Try with a fresh git clone of the repo. If your brackets-shell local copy has been around for a while, sometimes the build & deps folders can get in a bad state. (I'm assuming you haven't modified the source at all. If you have, try with an unmodified copy of the source first to make sure it builds correctly without any of your changes).
Check that python --version shows 2.7.x
Verbose build output would also be helpful in diagnosing issues like this, but unfortunately there's not yet an easy way to get that...
If you follow the instructions on bracket-shell's wiki page, the Windows executable should be created in the Release directory.
After installing Qt SDK for Open Source C++ development on Mac OS by following the respective steps
Note for the binary package: If you have the binary package, simply
double-click on the Qt.mpkg and follow the instructions to install Qt.
Yes, that is all I have done to install Qt on MacOsX. Everything was going fine, until I run a sample application, of which compile output resulted in:
No valid Qt version set.
Set one in Preferences
Error while building project qtilk
When executing build step 'QMake'
Canceled build.
Then I tried to change the respective Qt version in Preferences and I hovered over the Path, I realized my mkspec isn't set:
Then I tried querying qmake by qmake -query:
QT_INSTALL_PREFIX:/
QT_INSTALL_DATA:/usr/local/Qt4.6
QT_INSTALL_DOCS:/Developer/Documentation/Qt
QT_INSTALL_HEADERS:/usr/include
QT_INSTALL_LIBS:/Library/Frameworks
QT_INSTALL_BINS:/Developer/Tools/Qt
QT_INSTALL_PLUGINS:/Developer/Applications/Qt/plugins
QT_INSTALL_TRANSLATIONS:/Developer/Applications/Qt/translations
QT_INSTALL_CONFIGURATION:/Library/Preferences/Qt
QT_INSTALL_EXAMPLES:/Developer/Examples/Qt/
QT_INSTALL_DEMOS:/Developer/Examples/Qt/Demos
**QMAKE_MKSPECS:/usr/local/Qt4.6/mkspecs**
QMAKE_VERSION:2.01a
QT_VERSION:4.6.2
QMAKE_MKSPECS seems to be set here??
Will setting my mkspec solve my building problem? I tried setting by typing export mkspec=macx-g++. Still, mkspec seems not to be set to anything. I am all ears waiting for your answers. Thanks in advance.
To set the correct spec, use:
qmake -spec max-g++
