What are the compiler requirements for HLS with Quartus Prime Lite 19.1?

Hi,

Just as a side note - Ubuntu 16.04 is no easy fix for Quartus. When I initially had issues getting Quartus Prime Lite 19.1 running under Ubuntu 18.04, I installed Ubuntu 16.04 hoping that it would solve the issues since it is the officially supported version. But it did not fix anything. So I went back to Ubuntu 18.04. I had to do many things to get Quartus to run without any errors. Getting ModelSim and the Nios II EDK running were equally frustrating. But I eventually got them working. I found other people on the internet had run into the same issues.

GCC version 4.4.7 is not available in Ubuntu 18.04 nor Ubuntu 16.04, but it is available in Ubuntu 12.04. So I installed a chroot environment with Ubuntu 12.04 in my Ubuntu 18.04 system. I manually installed gcc 4.4.7 (because it was still not the default version). I had to install a few libraries and add an include directive for the compiler. I don't have ModelSim working yet under Ubuntu 12.04.

But by using both Ubuntu 12.04 for gcc and Ubuntu 18.04 for i++, I have been able to successfully make the /hls/examples/tutorials/usability/compiler_interoperability fpga_testbench.

It shouldn't be this difficult. I'm only putting up with this software mess because there is some hardware I want to use.
