QT5.4.1 compilation issue

Vibhu

Hi,

I am new to QT compilation and trying to compile Qt5.4.1 source for my project and getting below linking errors. Any idea what am I doing wrong.

You are trying to compile Qt 5.4 which was released in 2014. Nearly a decade ago! Why don't you update instead of spending time on this?!

Vibhu

@JonB Sorry, but I need to compile the same for my existing old project due to H/W and platform dependencies. Any inputs which might be helpful apart from upgrading QT.
I have downloaded QT5.4.1 from "https://download.qt.io/new_archive/qt/5.4/5.4.1/single/" and trying compilation.

@Vibhu
One of your errors appeared in 2016, https://forum.qt.io/topic/67217/qxcbintegration-cpp-undefined-reference-to-qspiaccessiblebridge.
@SGaist asked there

Which options did you pass to configure ? What was the configuration summary ?

I think you should answer that. [Here, I mean!]

Vibhu

@JonB Thank you for your response, I further checked and found the issue got resolved after correcting linking options in Makefile and upgrading sdk platfrom version being used to compile QT.
I will close this query.
