UPDATE: I was able to successfully compile master on raspberry pi after fixing a few compile errors. I was even able build all the debian packages (It took 30 hours)
But I really want to stick to a stable release v14.2.2, so I am trying to compile that branch. I managed to fix the first few errors by seeing how it has been fixed on master.
But I have got stuck on the following error. It looks like this is something deeper. It seems like it has something to do with the version of c++ itself. Is there any way to fix this error?
Please help
Thanks.
