Develop Qt5 app 32bits on Arch Linux 64-bit

[liewjls]

Hi,

I'm bit struggling compiling my Qt application to run on a 32bit linux PC. Currently I just reinstall my development PC is using Arch Linux 64-bit. I can build and compile my Qt application on my development PC. I understand Qt 5.7 isn't supporting for 32bit yet. How can i install Qt5.5 for my QtCreator to run on 32-bit PC?

thanks.

regards,
jenny

Certainly you can compile Qt on and for 32 bit Linux.

There is also an online installer for 32 bit linux available

You can install it by downloading here:

http://download.qt.io/official_releases/online_installers/qt-unified-linux-x86-online.run

That will get you the x86 (or 32 bit) version.

Or you can build it yourself with a 32-bit compiler/toolchain. That's usually the way I do it, so I can have my 64-bit development environment and have a 32-bit cross compiled version for distribution as well. This is pretty easy with Arch since arch can do 32bit (called multilib) installs that coexist with the 64-bit one.

thanks! i able to install the 32-bit on my Arch 64-bit. Instead i reinstall the 32-bit qt creator. I installed multilib-32 lib and add https://download.qt.io/online/qtsdkrepository/linux_x86/desktop/qt5_55/Updates.xml in my QT Maintaince tool. From there i can download and install 32 bits for my 64-bit Qt Creator.
