'make' escape characters inside quotes

Asked by Maike geng

I'm getting different results for escape characters in ubuntu's make when they are inside quotes.
Is that suppose to happen?

as example a command in makefile like:
    echo "line1\nline2"

gives output:
echo "line1\nline2"
line1
line2

Running that same output command in shell (bash):
<prompt:>echo "line1\nline2"
line1\nline2

I'm in 10.04 Lucid Lynx

Shell and Make don't use the same rules for enclosing character string. You will have to read manual. Be careful, escapes characters can be " or ', with different behaviors.

Try visiting the man page for echo and note the discussion of -e:

man echo

Then try: echo -e "line 1\nline 2"

Can you help with this problem?
