I am trying to build a software and gcc 7.x and g++ 7.x is giving too many compiler errors.  I want to try 6 to see if these errors minimize or go away.  Thanks for the help.

You seem to be having some difficulty getting an older version of the
compiler running. Perhaps it might be useful to go back to the
beginning and see if there is an alternative solution.

What kind of compiler errors are you getting? Post the gcc command
line and a sample of the errors to see if anyone has suggestions for
resolving them in gcc7.x.

You can use the help option to get more information about a lot of topics.

You can use gcc options to determine which version of C the compiler
will compile. There are also options to control which warnings are
generated, and possibly turned into errors by a -Werror option.

Use the info command:

info gcc

and enter the info search command: (CR=press enter)

/-std=CR

to find the relavent section.
