Compilation of QT Property Browser

Printable View

Hello all,

I am using QT 4 (the latest GPL version released by Nokia)

I download QT Property Browser from doc.trolltech.com/solutions/4/qtpropertybrowser/index.html

I am using VC++ 2008, with QT Visual Studio Add-In Installed.

I try to build simple project, under qtpropertybrowser solution.

Here is the error message I obtained :

Code:

Any suggestion to pass the compilation will be very much appreciated.

Re: Compilation of QT Property Browser
OK. Finally I figure out the workaround, I need to manually run the following command before clicking on the build all button.
Code:

moc qttreepropertybrowser > qttreepropertybrowser.moc moc qtpropertymanager > qtpropertymanager.moc moc qteditorfactory > qteditorfactory.moc
Not sure why. QT people should include these command in their build file :(

Re: Compilation of QT Property Browser
I confirm there is a problem with the buildlib pro of the 2.5.1 file imported in VisualStudio VS2005 at least with QT 4.6
- No import library created
- No export in the library ( dll_export not defined )
- Error message importing the pro file ( see ScreenShot attachment) with the last VS Addin

I suceeded in compiling it without a problem with :
Code:

cd buillib qmake nmake
but now i get some strange linking problems:

I have a class derived from QtPropertyBrowser
Code:

class PropertyEditor : public QtTreePropertyBrowser { Q_OBJECT public: PropertyEditor(QWidget *parent=0); ~PropertyEditor(); void setObject(QObject* object); public slots: void updateObjectProperty(QtProperty * property, const QVariant & value); private: QObject* _object; QtVariantPropertyManager _manager; QtVariantEditorFactory _factory; };
I get unresolved symbol in linking:
Code:

public: static struct QMetaObject const QtTreePropertyBrowser::staticMetaObject" (?staticMetaObject@QtTreePropertyBrowser@@2UQMetaObject@@B)
Do someone have an idea about what could cause this kind of problem?

I didn't have those problems with QT 4.5 and QtPropertyBrowser 2.5

Re: Compilation of QT Property Browser

Ok, if anyone is still having problems, here is what worked for me ( after a day of beating my head against the computer ).
Before opening the qtpropertybrowser.pro with VS2008
cd to qtpropertybrowser dir using the VS2008 cmd then run
>configure -library
exit cmd,
now open qtpropertybrowser.pro with VS and it should now open buildlib.pro properly as QtSolution_qtpropertybrowser_2.5.vsproject
NOW... go to QtSolution_qtpropertybrowser's property window and browse to C/C++ -> Preprocessor
there you should notice an entry called QT_QTPROPERTYBROWSER_IMPORT
change that to QT_QTPROPERTYBROWSER_EXPORT ( that is the main culprit )
and walla all of a sudden it compiles and no more missing *.moc files and inconsistent dll linkage warnings

Re: Compilation of QT Property Browser
I still get the problem with the unfound *.moc files, even after changing to using QT_QTPROPERTYBROWSER_EXPORT. If I manually create just one of the MOC files using
Code:

C:\Qt\4.6.2\bin\moc.exe .\qttreepropertybrowser.h > qttreepropertybrowser.moc
and rebuild I start getting a number of other errors (see otuput below). You will notice that there are still two MOC files missing, as expected. If I manually MOC those two remaining missing files I get literally hundreds of similar build errors.

I'm using Qt 4.6.2, QtPropertyBrowser 2.5.1, Windows 7, VS 2008. If anyone has seen these errors and have managed to get them sorted out, please let me know.

Thanks
Stefan

Re: Compilation of QT Property Browser

If I attempt to load just buildlib.pro into VS2008, after running configure.bat on a freshly extracted qtpropertybrowser 2.5.1, I get the following error: ..."Cannot add moc step to file..." (see attached screenshot).

This is the import output:

--- (Import): Generating new project of buildlib.pro file
--- (qmake) : Using: c:\qt\4.6.2\bin\qmake
--- (qmake) : Working Directory: C:\Qt\qtpropertybrowser-2.5_1-opensource\buildlib

--- (Import): Added buildlib.vcproj to Solution

When I atempt to build the project I (obviously) get the following error in the buid output:

Re: Compilation of QT Property Browser

I managed to get QtPropertyBrowser building, but I had to manually edit the "Generated Files" section of the vcproj file that was created by the Qt VS plugin to remove a bogus "Debug" filter and add a build directive for "qteditfactory.moc".

I added the following to buildlib.vcproj:

Code:

<File
				RelativePath="debug\qteditorfactory.moc"
				>
				<FileConfiguration
					Name="Debug|Win32"
					>
					<Tool
						Name="VCCustomBuildTool"

I am now able to get a debug and release build of QtPropertyBrowser 2.5.1 using Qt 4.6.2 on Window 7. I believe that the problem here is a bug with the Qt VS plugin. Anyone care to comment on that?

Re: Compilation of QT Property Browser
I use static versions of this QtPropertyBrowser library because I get linker errors when attempting to use DLL's - something about staticMetaObject.

These are the steps that I follow on Windows 7, Visual Studio 2008, Qt 4.6.3:
1. Unpack the Files from the archive (qtpropertybrowser-2.5_1-opensource.zip)
2. Change to the qtpropertybrowser-2.5_1-opensource directory
3. Run the configure script (configure.bat): configure -library
4. Run qmake: $(QTDIR)\bin.qmake.exe
5. Manually run moc.exe on:
  1. qteditorfactory.h
  2. qtpropertymanager.h
  3. qttreebrowser.h
6. Copy moc files to intermediate directories (Debug, Release)
7. Open qtpropertybrowser.pro with Visual Studio Qt plugin
8. Change the Configuration Type for both Debug and Release to Static Library (.lib)
9. Change the Output Directory and the Intermediate Directory to $(ConfigurationName)
10. For Release and Debug modes, change QT_QTPROPERTYBROWSER_IMPORT to QT_QTPROPERTYBROWSER_EXPORT for C++ >> Preprocessor >> Preprocessor Definitions
11. Remove Post-Build Event which will attempt to copy a .dll to $(QTDIR)\bin
12. Build Debug and Release libraries
Once the libraries have been built they will be located at ...\qtpropertybrowser-2.5_1-opensource\buildlib\[Debug\Release]. Other libraries that link against them should refer to them there.

With this set of steps I don't get any of the compiler or linker errors mentioned above.
