I'm using Quartus 20.2 on CentOS 7 for a10gx card/emulator. I've installed GCC 7.2.0 as per mentioned in Getting Started Guide and it works.
We would like to know best OS supported by Intel FPGA SDK. We want to use system compiler instead of additional installations. I'd appreciate pointers regarding support for future releases of Quartus, OS, GCC etc. A stable environment is expected throughout the project upcoming years.
