I use Qt 5.0.1 with Windows SDK 7.1. If I create a new application, the Kits page of the New app wizard offers to create Debug and Release directories:
Debug: C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Debug
Release: C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Release
1) If I compile the app in Debug mode, Qt Creator creates two directories:
C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Debug\debug
C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Debug\release
The executable will be created in the former, C:\...-Debug\debug.
2) If I compile the app in Release mode, I will get another pair of directories:
C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Release\debug
C:\Projects\MyProject-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Release\release
In this case, the executable will be placed in the latter, C:\...-Release\release.
What is the logic behind this nested directory structure? When does the IDE use the directories C:\...-Debug\release and C:\...-Release\debug?
UPDATE
#phyatt pointed out that turning off shadow building in project settings eliminates the problem. The debug and release directories will be generated inside the project's source directory:
C:\Projects\MyProject\debug
C:\Projects\MyProject\release
Unfortunately, this doesn't answer the above question. Moreover, now the project settings page displays a warning:
An incomplete build exists in C:\Projects\MyProject, which will be
overwritten.
If you are only using a single compiler, I would go into the Projects tab > Build > General > Shadow Build, and uncheck Shadow Build.
This will simplify the configuration and folder structure, and may fix the bug for you.
Maybe go in and do a build clean for good measure.
Hope that helps.

I downloaded Qt5.6 VS2013 32bit and try to run the official example of QtWebEngine.
I just followed the instruction but
When linking it gives out an error of
LNK1104 file not found c:\Users\qt\work\install\lib\Qt5Widgetsd.lib.
However, I have no idea of where this path c:\Users\qt\work\install\lib\ comes from.
I did text search in all directories of example folder and no hits other than generated files(makefiles and pdbs).
I also checked system environment variables but no hits.
Furthermore, I checked Qt Creator'r Projects panel and its Build Environment and still no hits.
Did I miss something?
P.S. this error was given out by linking DemoBrowser example of QtWebEngineWidgets pro
The link is generated by qmake when it generates the build scrip from the qt project file (*.pro). It is based from the qmake application path that is generaly installed together with the libraries (check you qt kit setup to change it if needed: Jst browse to qmake.exe application).
Then try regenerate the build script. It should fix the issue.
You may also have issue with installation not being in debug mode; you are trying to use Qt5Widgetsd.lib library instead of the non-debug one Qt5Widgets.lib
In one of my programs I use QWebView to load and print reports made from HTML documents. So while deployment I copy these libraries, in additional to all other relevant Qt libraries:
Qt5WebKit.dll
Qt5WebKitWidgets.dll
Qt5PrintSupport.dll
plugins/printsupport/windowsprintersupport.dll
After testing on destination machine I've found that printing doesn't work. Thanks for Dependency Walker I've get all the missed libraries. Here is the list:
Qt5Multimedia.dll
Qt5Positioning.dll
Qt5MultimediaWidgets.dll
Qt5Qml.dll
Qt5Quick.dll
Qt5Sensors.dll
Qt5OpenGL.dll
Ok, I can understand why it wants Qt5Multimedia.dll. Browser can play sound etc. But QML! Why I need all these libraries related to QML?? I don't use neither OpenGL nor sensors or positioning. So it's just unnecessary in my case.
And so my question - is there way to deploy only libraries I need in actual fact? And get the program work of course.
I would suggest you to use windeployqt.exe.
From the docs:
The Windows deployment tool can be found in QTDIR/bin/windeployqt. It
is designed to automate the process of creating a deployable folder
that contains all libraries, QML imports, plugins, translations that
are required to run the application from that folder. This is used to
create the sandbox for Windows Runtime or an installation tree for
Windows desktop applications that can be easily bundled by an
installer.
This is how I do:
cd [my program dir]
mkdir RELEASE
cd RELEASE
copy ..\"progname.exe" .
set QTDIR=C:\Qt\Qt5.4.1\5.4\mingw491_32\bin
call %QTDIR%\qtenv2.bat
windeployqt --force "progname.exe"
You could adapt that for your need by changing [my program dir] to your application's folder (containing the .exe file), QTDIR to your Qt MinGW folder (that's what I use) and progname.exe with the name of your executable file.
It will create a release directory with your executable and the needed Qt libraries (.dll's, etc).
I'm using the latest QT SDK under Windows and am wondering how I specify a working directory based on the build type. I need a different working directory and release and debug builds of the same project. For instance, I have a run target called MyProgram and two build targets, Release and Debug. MyProgram depends on some external libraries. When I run MyProgram in debug I need it to run in the directory C:\foo\bar\libraries\debug, however when I run it in release I need it to run in directory C:\foo\bar\libraries\release. It would appear that the Working Directory is only dependent on the run target and not on the build target. Is there a way to specify a Working Directory based on both run and build target? Could I use a variable to specify release/debug in the Working Directory?
Yes, you can. Delete the .pro.user file in the project directory, open the project, and set "Create build configurations" to manually, and check "Use shadow building". Now you can specify the target directories.
BTW, for a better solution for your missing libs, check out the Qt resource system: http://developer.qt.nokia.com/doc/qt-4.8/QResource.html
I must be doing something totally stupid here, but I can't get the PLCrashReporter framework included in my project. Here are the steps I took to get the framework:
Downloaded the .dmg file from the official project site on google code
Copied the CrashReporter.framework folder to the root directory of my project
Added the framework by going to my project, selecting the target, going to the Build Phases tab, opening the Link Binary With Libraries section, clicking the plus sign, and adding the CrashReporter.framework folder
I am pulling in the framework in my class file by using
#import <CrashReporter/CrashReporter.h>
When I try to compile under 4.3 simulator, I get the following errors:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_PLCrashReporter", referenced from:
objc-class-ref in AppDelegate+CrashReporting.o
"_OBJC_CLASS_$_PLCrashReport", referenced from:
objc-class-ref in AppDelegate+CrashReporting.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
When I compile under the device, everything is fine. Is there some sort of header or library search path I need to include?
The app compiles under XCode 3 without issues under all configurations.
I had the same issue and was able to resolve it. Here are the steps I completed...
Download the PLCrashReporter source release and unzip.
Open the PLCrashReporter xcode project. This project is setup to use an old SDK, update all the required SDKs for each target to get rid of the warnings. This is also required to compile in the next step.
Navigate to the CrashReporter-iPhoneSimulator Target. Under the Build Settings: a) set "Perform Single-Object Prelink" to "No", b) set "Mach-O Type" to "Static Library".
Select CrashReport-iPhoneSimulator : [IOS simulation (ie iPhone 4.3 Simulator)] and click build.
Navigate to your build directory for the PLCrashReporter. For me, it was /Users/username/Library/Developer/Xcode/DerivedData/CrashReporter-(random characters)/Build/Products/Debug-iphonesimulator
Copy the libCrashReporter-iphonesimulator.a from the build directory in step 5 to the iphone application project directory you want to add the crash reporter to.
Open the your iphone application project in xcode.
Download the PLCrashReporter binary release and extract the framework to a local directory.
Add the CrashReporter framework to your project using this SO post.
Following the same procedure as step 9, add the libCrashReporter-iphonesimulator.a static library to the "Link Binary with Libraries" section of the build phases. No *.framework directory is needed when adding a static library.
Review the "Link Binary with Libraries" in the Target. Make sure the libCrashReporter-iphonesimulator.a is listed above the CrashReporter framework. You can drag and drop to reorder.
I hope this helps.
For anyone else looking for this information:
I followed the same steps given above however I was getting errors. I deleted the static library and only included the framework (which you can get from their dmg).
It worked perfectly for me. I think the process of creating static library by building the project was old (before they created a framework).
Thanks.
Don't forget to include
libstdc++.dylib
in "Link Binary With Libraries".
I'm compiling Qt from source, but I don't want to extract the source each time I want to build it.
How can I clean previous configuration with the configure tool?
For Qt4 and earlier, try this:
nmake confclean
You can then re-configure and re-compile QT.
As noted in the comments, this no longer works in QT 5. This is due to the fact that the Qt project now uses separate sub-modules for different parts. If you have a local clone of the Qt git repos, you can try calling this from the main Qt directory:
git submodule foreach --recursive "git clean -dfx"
As noted here, there may be some problems if you have a downloaded source archive. The link I posted suggests using a shadow build instead so the process of making a clean configuration is as simple as configuring to build at a new shadow build destination.
As of today (Qt 5.9.0 beta2) there is no confclean target in Linux, and you need to manually remove .config.cache file to reconfigure.
Note that make distclean doesn't help at all.
For the latest versions, use a shadow build, then you can just nuke your directory. My batch file for configuring effectively creates a new folder, moves into it, then calls configure.
Then you just go into the shadow directory and run 'jom'.
When you want to make a different configuration, just use a different shadow directory.
This effectively means that your source tree doesn't get filled with build artifacts, which are impossible to remove when you want a different configuration. Trust me, this is the thing to do....
mkdir shadow_dir
cd shadow_dir
%~dp0\src\configure.bat ....
On Ubuntu:
make confclean
BTW, the following text displayed after run configure:
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /home/ben/qt/qt-everywhere-opensource-4.7.4-debug
To reconfigure, run 'make confclean' and 'configure'.
