[Newbie question] Strange errors trying to build the JDK

[Zambonifofex]

Hello David, sorry for delaying to reply.

By using ‘less’, I was able to find ‘NAWK’ in my
‘~/jdk/build/linux-x86_64-normal-server-release/spec.gmk’ file:

    NAWK:=/usr/bin/nawk

However, I was not able to find any variables named ‘DUMP_SYMBOLS_CMD’.
