Compiling openMSX for Armbian 5.59 xenial

I had two versions 5 and 8, I thought 5 was the defaultm removed them both, installed g++-8
in compile it says make:g++:command not found

I think that the command must be g++-8 because when I type "g++ --version" to know the version I use, it says "command not found" but it works when I type g++-8 --version

Thanks for your feedback

After nearly one hour of compilation..i got this fatal error.. killed signsl terminated program cc1plus

Look at snapshot

Hoe much RAM does that system have?

RAM is 1 GB... I think it is CPU clock issue as shown in dmesg..
What are other possibilities to compile it?? I have other PC machine with lubuntu..can i compile there then transfer the openmsx in opt folder from PC to Android TV box??
I will try to compilr openmsx 16 and see if the same happens

I think the CPU frequency errors are a red herring. That "fatal error: killed signal terminated program cc1plus" error usually comes out due to an out-of-memory error. So, something to try is to increase the size of the swap partition.
