Updated to? 20.04 LTS is due out in a a week or two. I;m on 19.10, which works.
No, it isn't. The actual error is in the do_compile log you posted and is:This is the error message
The "needs gcc 8" is probably correct - gcc 7.5 certainly doesn't have the option, 8.4 does.gcc: error: unrecognized command line option ‘-fmacro-prefix-map=/home/openvixbuilder.....
If you wonder what it does, it's this:
-fmacro-prefix-map=old=new
When preprocessing files residing in directory old, expand the "__FILE__" and
"__BASE_FILE__" macros as if the files resided in directory new instead. This can be
used to change an absolute path to a relative path by using . for new which can result
in more reproducible builds that are location independent. This option also affects
"__builtin_FILE()" during compilation. See also -ffile-prefix-map.
