@JG97 said in QT 5.8.0 64 Bit with MinGW-w64 Configuration:

How do I configure the x86 package for building 64 bit applications?

You can't. You install Qt 5.12 MinGW 64bit and MinGW 64bit (it is available in the installer under Tools) and use this for 64bit apps. For 32bit apps you do the same but 32bit...

@sierdzio Thank you. Will look into it.

I have found a solution here.
Looks like Ubuntu couldn't run 32bit binary, but it's working now.

Ok... well it seems now that the answer is that I need to use -prefix <> option.

@cskr
Hello, Did you find any solution for this problem???

I was able to solve the problem where fontconfig was not able to find libexpat by adding the following in my xplatform qmake.conf

QMAKE_LINK = $HOST-g++ -lts -L/opt/qt/qt5.9.1arm/lib -Wl,-rpath -Wl,/opt/qt/qt5.9.1arm/lib QMAKE_LINK_SHLIB= $HOST-g++ -lts -L/opt/qt/qt5.9.1arm/lib -Wl,-rpath -Wl,/opt/qt/qt5.9.1arm/lib

Thanks @J-Hilk
The link provided needs other configuration.

My machine configuration is

Red Hat Linux - 32 bit
Qt creator 1.2.92, based on Qt 4.6.0 (32 bit)
Make version: GNU Make 3.81
Qmake version: 1.07a (Qt 3.3.6)

Please let me know what are the pre-requisites for a plugin. I want to create a menu item for Qt creator.

Thanks in advance.

You're welcome !

I'm pretty sure not all these packages are necessary but at least you have it working now :)

@kfrosty Thank you! Did work for me too! :)

You have here a list of the modules and their state.

QtWebkit as been deprecated and removed.
QtQuick1 as been deprecated and removed

You can still build them from sources but you have to clone them specifically.

@SGaist Thanks. Seems like that is exactly what i need.

@AliReza-Beytari

Ps. are you sure this works with 5.7 ?
Only Qt 5.6 is mentioned.

@Mark81 it's a compiler issue: https://github.com/raspberrypi/tools/issues/41

Just saw something, why are you using sudo ? That's not a good idea when you are building anything.

I didn't try. 5.4.1 is enough for me

@The2Ring

welcome to devnet forum

I have not done a build of Qt libs myself for some time. Therefore, I am not completely sure, but the building scripts are typically not happy about the use of backslashs '\'. Those are certainly the main folder separators for windows, but may need escaping. The scripts of Qt are originally coming from linux. Therefore in a lot of places it is better to use the forward slash '/' instead.

I have seen that you have used already the forward slash with LIBS and INCLUDEPATH. So you are aware of the issue. However, you have used with configure.bat back slashes.

In my opinion it is certainly worth a try with forward slashes. This is sometimes as a miracle and solving issues which are hard to understand.

we're storing our Qt build in our version management system

This is a strange thing to do, since Qt guarantees binary compatibility between minor versions, but well, you're free to choose. Unfortunately, I don't see how you could decrease the size further, beside deleting the docs, as the libraries are in the /lib directory and they're the next biggest size. Maybe store only the libs that you're using, i.e. these that you're going to deploy. No point in keeping QtXml if you're not using it, right?

@Mike_Blackman said:

My application fails to load libqxcb.so plugin, because libqxcb.so plugin fails to locate Qt libraries. Prebuilt Qt solves this problem by using relative RUNPATH value within libqxcb.so.

Sorry, I don't know what the prebuilt libraries did to the RPATH/RUNPATH. You can ask the Qt engineers in the Interest mailing list: http://lists.qt-project.org/mailman/listinfo/interest (Subscribe to the list first, then post there)

@Ajith_P_V Yes that is right, you don't need to add the physical device. That was really just an extra option in case that was convenient to you later on : )

Have a look at creating kits for cross compiling in the qt docs if you can find it! - there are quite a few bits of info out there that may fill in the gaps I have left. I only gave the general steps required.

@JKSH Thank you very much for your answer, I've successfully built Qt using your tutorial!

Back on topic. I found that when building Qt you can specify to build only the module you need at the nmake stage,

e.g. nmake module-qtbase

That way it won't try and build all the other modules and qml libs.

Solved. Just started compiling 5.4.2 and just small issues that are easier to resolve.

Hi and welcome to devnet,

you can create your Project Wizard in Qt Creator

No, I don't have any problem with build environment. I want to know the list of parameters. For example like in Xcode.

@sierdzio said:

Thanks a lot for the clarification.

IIRC, QtCore will also use pcre for QRegularExpression

Are you sure all available modules were built ?

ok, i will ask there. Thanks!
