Dear Eli,
Thank you. It worked. Another question is about the extract of make manual:
5.1 Recipe Syntax
A variable definition in a “rule context” which is indented by a tab
as the first character on the line, will be considered part of a
recipe, not a make variable definition, and passed
to the shell.
I have the following makefile:
all: file1
        var1=wwwww;echo $var1
        @echo lllllll

The result was:
var1=wwwww;echo ar1

Why var1 can not be printed correctly? Does make considers two
different shells for  (var1=wwwww) and (echo $var1)?
How can i have a variable assignment for each command of a recipe?
