How to view g++ long error message

[Lambda]

I am using g++ to compile a program.
g++ outputs so many warnings and errors that
I cannot see the first error message that I think I should fix first

I try to use 'g++ exer.cc | less' but it doesn't work.

I try to 'g++ exer.cc er' but it doesn' work either.

What can I do with it?

news:gnu.g++.help or any manual for your shell to see what syntax
you need for redirecting the standard ERROR output (like "2er"
or something).

When using bash, try

g++ exer.cc 2>&1 | less

or

g++ exec.cc >er 2>&1

when you want the errors to end up in file "er".

Try 'g++ exer.cc | & less' OR
'g++ exer.cc | cat & er'
