Build cross Qt library and use in different Desktop

Jignesh Patel

Hi,

We have successfully cross compile qt for imx6 and installed in my desktop. We can able to successfully cross compile qt application in my laptop.

Now We want to use same cross library in other desktop but we are facing issue for path that has set at configuration time.
We have checked path of all qt variable using "qmake -query" it shows my local path so i can not use qt cross lib by simple copy,paste and give permission.

output of qmake -query:

$ ./qmake -query
QT_SYSROOT:
QT_INSTALL_PREFIX:/media/Myqt_crosslib/Qt-5.7.1-master/SmartCalLib

QT_VERSION:5.7.1

QT is also use this path lot more in lib folder.

Is there any way we can compile qt library in one Desktop and able to use in different desktop for cross compiling?

Thank you,

Hi,

You need a more recent version of Qt to make it relocatable.

You really should consider it, Qt 5.7.1 is more than outdated and not even an LTS release.

Thank you for reply @SGaist ,

we are at a stage and can not change the qt revision.
I got a solution for another way by copying and past the QT library and toolchain on the same path on all desktops.

Best Regard,
