I am new to using Qt (and building it). I have searched on the web and landed at multiple ways of cross-building the Qt src for Beaglebone Black, of multiple versions, but haven't been successful to build any of those.
I am following the guide from one of the GitHub pages here.
The configure and make commands worked fine and didn't give any errors (just some warnings). But when I tried "make install", the build continued until I was bombarded with a bunch of errors for with the 'libQt5SerialPort.so.5' and fails ultimately with 'Error 1' and 'Error 2'.
Here's the terminal log which give the undefined reference errors:

I have tried clean building the same multiple times, but always faced the same issue.
Can someone please help with figuring out what is going wrong here?
Thanks a ton.
To anyone trying to build Qt for cross-compilation for BeagleBone Black, following this guide properly would work.
PS: It should be kept in mind to download qtcreator with a version equivalent to or older than the qt-source being built.
