Problem Compiling Qt 4.8.7 on Windows 7

[Instigator]

Hi

I'm a complete newbie, so even if anyone is kind enough to help, I might need a simple explanation.

I'm trying to compile 4.8.7 on Windows 7, but I've encountered these errors.

Does anyone know what is causing this?

Thanks

This output does not show any error messages, please check your compilation again and locate the actual error.

BTW. are you locked to Qt 4.x? It is a very old release.

[Instigator]

@sierdzio Thanks for the reply, I appreciate it. I apologise for my lack of knowledge.

I ran

configure -release -opensource -confirm-license -static -no-sql-sqlite -no-qt3support -no-opengl -qt-zlib -no-gif -qt-libpng -qt-libmng -no-libtiff -qt-libjpeg -no-dsp -no-vcproj -no-openssl -no-dbus -no-phonon -no-phonon-backend -no-multimedia -no-audio-backend -no-webkit -no-script -no-scripttools -no-declarative -no-declarative-debug -qt-style-windows -qt-style-windowsxp -qt-style-windowsvista -no-style-plastique -no-style-cleanlooks -no-style-motif -no-style-cde -nomake demos -nomake examples

I received this message: WARNING: Using static linking will disable the use of plugins.
Make sure you compile ALL needed modules into the library.
Creating qmake...

It then said to run mingw32-make. It complied for about 45 minutes and stopped after:

mingw32-make[4]: *** [Makefile.Release:2404: tmp/obj/release_static/itemviews.o]
 Error 1

mingw32-make: *** [Makefile:596: sub-plugins-make_default-ordered] Error 2

I can't see any other information on these errors.

As for using Qt 4. I attempt to download the newest version but it reaches 97% and then says 'Network error', 'Connection timed out'.

Thanks

Hi
Can i ask why you try to compile it yourself?

you can just download one from
https://download.qt.io/official_releases/qt/4.8/4.8.7/

(or any newer version, which is recommended)

[Instigator]

@mrjj Hi. Thanks for your reply.

I was just following some instructions. It said to download the zip version, extract and then run:

$ configure -release -opensource -confirm-license -static -no-sql-sqlite -no-qt3support -no-opengl -qt-zlib -no-gif -qt-libpng -qt-libmng -no-libtiff -qt-libjpeg -no-dsp -no-vcproj -no-openssl -no-dbus -no-phonon -no-phonon-backend -no-multimedia -no-audio-backend -no-webkit -no-script -no-scripttools -no-declarative -no-declarative-debug -qt-style-windows -qt-style-windowsxp -qt-style-windowsvista -no-style-plastique -no-style-cleanlooks -no-style-motif -no-style-cde -nomake demos -nomake examples

$ mingw32-make

I encountered an error: 'sub-xmlpatterns-make_default-ordered] Error 2' so made changes to /src/xmlpatterns/api/qcoloroutput_p.h after finding the solution through a search, and compiled again and then came across another error further on, which I posted above. Are you saying I don't even need to compile it, I can just download the Zip version and extract it? Why would instructions say I need to compile it if that's not necessary?

As you can probably tell, I'm really new to this. Thanks for your time.

Hi,

No, not the zip file. The installer pointed to by @mrjj. But as suggest you should rather use Qt 5 as Qt 4 as reached end of life.

As for the download problem, did you consider changing the mirror used ?

@Instigator said in Problem Compiling Qt 4.8.7 on Windows 7:

Why would instructions say I need to compile it if that's not necessary?

Because for some people it might be necessary. But that's advanced stuff. If you want to start, use the installer as pointed out by @mrjj and @SGaist.

And in any case, don't start new development with Qt 4. Use Qt 5.9.x or 5.10.

Regards.

[Instigator]

@aha_1980 @mrjj @SGaist Thanks everyone for the help. I downloaded qt-opensource-windows-x86-5.10.0.exe from official_releases/qt/5.10/5.10.0/ and I'm installing it now, though have just received an installation error, which I had to click Ignore to continue:

Cannot start: "{0,3010,1603, 5100} msiexec/i C:\Qt\\tools\Perl52213\strawberry-perl-5.22.1.3-32bit.msi /quiet": Process failed to start: No such file or directory.

[aha_1980]

@Instigator: It tries to install Perl, which fails for some reason (I think this is a known bug, I read about this already).

I think that is nothing to worry about - you should be able to start coding now :)
