Qt 5 Library Build for WEC7 failed

CRiessland · wrote on 24 Oct 2014, 07:43

I'm trying to build the Qt 5.3.2 library for WEC7. For this purpose I followed those guidelines:

"Windows CE - Working with Custom SDKs":http://qt-project.org/doc/qt-5/windowsce-customization.html
"Installing Qt for Windows CE":http://qt-project.org/doc/qt-5/install-wince.html

If fulfilled all requirements. My Setup:

• Visual Studio 2008 Professional SP1
• Active Perl 5.3.16
• Windows Embedded Compact 7
• ARM Platform: Freescale i.MX6

I created a Custom Build Specification:

• Created wince70embedded-iMX6-msvc2008 based on wince70embedded-armv4i-msvc2008
• Set CE_SDK = phyFLEX-i.MX6 SDK
• Set CE_ARCH = ARMv4I
• Added Preprocessor Definitions UNDER_CE, WINCE, $(ARCHFAM), $(ARCHFAM), _UNICODE, UNICODE

Afterwards I

• Added C:\Qt\5.3.2_CE\qtbase\bin to PATH
• Used vcvars32.bat to set Environment variables
• configure -platform win32-msvc2008 -xplatform wince70embedded-iMX6-msvc2008
• Build using nmake

After a while the build fails with:

The List is longer, but I can't post it all.

What am I doing wrong? I'm new to QT and WEC7, so I hope you can point in the right direction.

I had the same problem. After using configure -xplatform wince70-myplatform-msvc2008 -developer-build -opensource -confirm-license -nomake tests -nomake examples -no-accessibility -opengl es2 -skip qtactiveqt -skip qtwinextras -skip qtlocation I was able to build the QT5 libraries. Unfortunately I was not able to build the quickcontrols libraries. Maybe "-no-accessibility" is responsible for that. But without this directive I get the same error as you.

I tried your configuration:

@c:\Qt\5.3.2_CE>configure -xplatform wince70embedded-iMX6-msvc2008 -developer-build -opensource -confirm-license -nomake tests -nomake examples -no-accessibility -opengl es2 -skip qtactiveqt -skip qtwinextras -skip qtlocation@

with my mkspec:

@# qmake configuration for Windows Embedded Compact 7 with VS2008 on ARM targets

This is just a template for creating WEC7 mkspecs for ARM targets

Replace the SDK name with actual SDK name.

include(../common/wince/qmake.conf)

CE_SDK = phyFLEX-i.MX6 SDK # replace with actual SDK name
CE_ARCH = armv4i

DEFINES += QT_NO_CLIPBOARD QT_NO_ACCESSIBILITY QT_NO_NATIVE_GESTURES QT_NOSTANDARDSHELL_UI_MODEL _CRT_SECURE_NO_DEPRECATE _WIN32_WCE=0x700 $$CE_ARCH AMRV7 armv7 ARM UNDER_CE WINCE $(ARCHFAM) $(ARCHFAM) _UNICODE UNICODE

QMAKE_RC = rc

QMAKE_COMPILER_DEFINES -= _MSC_VER=1400
QMAKE_COMPILER_DEFINES += _MSC_VER=1500@

But now I get the following error:

@c:\qt\5.3.2_ce\qtbase\include\qtgui../../src/gui/opengl/qopengl.h(82) : fatal error C1083: Cannot open include file: 'GLES2/gl2.h': No such file or directory@

Are there any additional settings (Qt, Compiler, Visual Studio, Windows, PATH, etc.) I might have forgotten? Maybe even something that is not mention in the installation guide, but has to be set/configured for an WEC7 Application to work.

Where can I find a complete log file from the library build? Maybe there are even more Warnings/Errors that can give me a hint.

I am a Qt5 and WEC7 Newbie.
I have redirected my output to a file. So I could analyze the build errors. I also don't know where you can find the complete log file.

I found the header files and libs for GLES2 in the SDK of my device. I think if your device provides OpenGLES2 support, it should provide headers and libs.

Additional to your configuration, I installed python (Active Python > = 2.6.x http://www.activestate.com/activepython/downloads , because I got python errors in my build log. And I ensured that perl is in my PATH.

I was able to build most of the libraries so that I can execute Widget and OpenGL applications on my device. Unfortunately QML applications are not running or the displayed window shows nothing (although QtQml.dll is built). For that I'm looking for a solution. Even a QML helloWorld program is not running when executing via qmlscene. Maybe a problem of missing ws2.dll or libgles2.dll on my device.

Can you please tell me if these dlls are available on your device?

After I disabled opengl with “-no-opengl” I was able to build the library, but I still cannot compile applications for my device. After the library build I added the default Qt/WinCE version in the Visual Studio Qt Options. Is it correct that I added the qtbase folder for 5.3.2? To get it working I had to copy my Build Specification folder "wince70embedded-iMX6-msvc2008" and rename it to default.
Now I can create an Qt Windows CE application, but the build throws a lot of errors.

Cannot open include file: ‘QtGui/QMainWindow’
I changed that to ‘QtWidgets/QMainWindow’ and the error was gone, but I thought I should work out of the box. I also have Qt 4.8.6 installed as standard Windows version. Maybe Visual Studio mixes something up here? Because ‘QtGui/QMainWindow’ would bei correct for 4.8.6.
Error C2039: ‘WFlags’: is not a member of ‘Qt’
Changed it to WindowFlags and the error was gone.
Now I have several build errors:

Should it really be that complicated to get Qt for Windows Embedded Compact to work?

I found my missing dlls in windows folder (hidden and protected).

Why not using Qt Creator?

Configuration of Kit

Open a project in creator
Projects – Manage Kits – Build&Run - QtVersions – Add
qmake location: choose qmake.exe from your qtbase build.
Apply
Switch to tab Kit - Add
choose right compiler and Qt version, that you have created in previous step.

You can create a VS project from a creator project (qmake.exe -tp vc <project name>)

I never used Qt Creator before, so I thought it would be easier to start with Visual Studio. But now I tried it.

There were no build error's any more and after I added the missing dll's it was finally possible to run a simple Qt Application on my target.

Thank you!
