Compiling qt5 in msys and mingw

mctree

Thanks. I am using cmd + mingw now. I don't know how to disable WebKit but while I run the configure, it report there is no DirectX SDK, I skip it and it keep running. Then I run the mingw32-make to make, it takes long time to run ... but finally it ends up with reporting missing python27.dll. I have python27 installed in c:/python27 but seems the configure detect that

....\include/QtGui/../../src/gui/opengl/qopengl.h:55:25: fatal error: GLES2/gl.h: No such file or directory
compilation terminated.

How to correct that? Thanks.

Do...
@
configure.bat -developer-build -opensource -nomake examples -nomake tests -opengl desktop --no-webkit
@
...to use your graphics card's OpenGL instead of DirectX, and to disable WebKit.

*checking for python... (cached) /bin/python2.5

...

Why it detect python2.5 instead? How to correct that? Thanks.

Because you have multiple versions of Python in your machine, and the configuration tool found Python 2.5 first. Move your environment variables around, and make sure Python 2.7 is listed first. Same with Perl.

--no-webkit gives an error for me. But -nomake webkit seems to work

I have tried following the instructions on this thread and looked at many others but getting very frustrated!

I have mingw installed in c:/mingw under WinXP and the dependent packages installed (Perl, Pyhton, Ruby). Paths set. I have the qt source in c:/mingw/local/qt. In this directory I have tried running:

configure.bat -prefix c:\mingw\local\qt -developer-build -opensource -opengl desktop -platform win32-g++ -nomake examples -nomake tests
-nomake webkit

but I get:

C:/mingw/local/qt-src/qtbase/configure -prefix c:\mingw\local\qt -developer-build -opensource -opengl desktop -platform win32-g++ -nomake examples -nomake tests -nomake webkit
'C:\mingw\local\qt-src\qtbase\configure.exe' is not recognized as an internal or external command, operable program or batch file.
*** qtbase/configure exited with non-zero status.

Notice the "\" before "configure.exe". What on earth am I doing wrong here? Is there some (undocumented) environment variable I have to set?

I haven't seen the double-slash issue before.

Are you using Windows command prompt or MSYS?

Try removing "-prefix c:\mingw\local\qt" (it's unneeded, since you're building into the same directory as the source code)

This is probably unrelated, but also try deleting/renaming the qtwebkit folder before configuring, and removing the "-nomake webkit" option (I have a feeling this option is invalid). If the configure script can't find the qtwebkit folder, it will omit the compilation of Qt WebKit without errors.

cmd. Sorry - accidentally edited that detail out of the final post. Also logged in as administrator so there should be no access issues.

The double slash is perplexing me! What is trying to launch configure.exe?

Tried that already - same result

I tried this because the suggested "--no-webkit" option elsewhere in this thread gives an error. But the least of my problems right now.

What's your version of MinGW? What's your Qt version, and how did you obtain it?

I have GCC 4.7.2 (from MinGW-builds), and Qt 5 source code from git (stable branch) that's a few days old. This command configured Qt without issues for me:

@
configure.bat -developer-build -opensource -confirm-license -nomake demos -nomake examples -nomake tests -opengl desktop
@

MinGW 4.7.2 from mingw.org. (Not the sjlj unwinding version). Qt5.0.2 from qt-projects. But things don't look to be getting as far as the compiler - it looks like there is some issue with the Qt build script/interaction with my environment.

[quote]configure.bat -developer-build -opensource -confirm-license -nomake demos -nomake examples -nomake tests -opengl desktop[/quote]

I have tried exactly this and I get exactly the same result! I have searched for a file called configure.exe under the qt directory and it's not there, notwithstanding the double slash issue. So I am wondering if there is some condition that is going awry under my environment and trying to invoke a file that is absent. Do you have any QT environment variable set?

JKSH

Very strange. I can't think of what the issue could be, sorry. Did you start with a clean source tree each time you tried?

I have no Qt-related environment variables set -- I've never set any, regardless of whether I compiled using MinGW or MSVC 2012. Here's my configure output: http://pastebin.com/6MN6aF6F At which step does yours fail?

I think so. I have certainly tried downloading a clean version. No difference.

OK.

[quote] Here's my configure output: http://pastebin.com/6MN6aF6F At which step does yours fail?[/quote]

Line 3! Whereas your version outputs "Please wait while bootstrapping configure ...", mine gives "‘C:\mingw\local\qt-src\qtbase\configure.exe’ is not recognized as an internal or external command, operable program or batch file."

I now understand a bit more about what is supposed to be happening - configure.exe is built in the bootstrapping process and finally linked in your line 76. I don't seem to be entering the bootstrapping process, rather trying to execute configure.exe from the off.

I suspect the fundamental issue is where this double slash is coming from. Maybe I will try on another machine in case there is something messed up with my version of Windows...

I had the double slash issue. I can't remember exactly how I fixed it though. I think the trick was to use the recommended build tools (the sljljljlj thingy one). I also had problems as my LIB and INCLUDE variables needed to be cleared before I built anything as mingw picked up a gtk+ library. I think the \ issue arises because PATH doesn't point towards the mingw configure. I'm sorry I can't remember the exact fix. If you want more info let me know.

About the "\configure.exe not recognized" error: it is qtbase\configure.bat that is trying to call it. qtbase\configure.bat can build configure.exe before calling it. To trigger the build create an empty file qtbase.gitignore
This tricks configure.bat and it builds configure.exe
Hope this helps. I was getting the same problem with Qt-5.0.2
