GCC5 is working good on Ubuntu 16.04, but i have another PC with Ubuntu 18.10 installed, and i can't just install gcc-5 with apt-get install, i guess gcc-5 package is removed from apt source, i believe i can find a way to install gcc-5 on Ubuntu 18.10 with some effort... but i would not try to, because VS2017 works good now :) You don¡¯t need to install GCC5. You can try build the code with GCC5 tool chain. If you find any issue, please submit BZ https://bugzilla.tianocore.org/.

Oh..I didn't notice that GCC9 is available now, maybe i should check the release News. Thank you :) Regards, Flynn > >Certainly, any issues people come across, please report. > >Regards, > >Leif
