build from src

[jamat13]

Short Story: I'm trying to build 4.5.n from src and get errors. Anybody a working build enviroment / howto please
Long Story: I have an app Im trying to display on a BeagleBone Black with chipsee LCD display.
The app builds and displays on 5.4.
The BBB has only libs for 4.5.x
I CAN build and display an example app on the BBB, but my app does nothing: blank screen nothing visible
I want to build the app on a desktop 4.5.x to see it does work
The only 4.5.x I can find is from src
Building QT failes repeatedly eg

The platform is easy (linux) so good story anyone?

Hi @jamat13, and welcome to the Qt Dev Net!

The BBB has only libs for 4.5.x

What distro do you have on your BBB? If it's Ubuntu, then you can install pre-compiled Qt 5 through apt-get.

Qt 4.5 is positively ancient, and it has not been supported for many years. Are you sure you want to use it? (I have never seen that error when building Qt, so I don't know how to solve it, sorry)
