I want to setup the same version for few projects in one place. I've tried:

use ExtUtils::MakeMaker;

WriteMakefile(
    VERSION_FROM => 'lib/project/version.pm',
    ...

In 'lib/project/version.pm':

package project::version;
use AnotherProject;
our $VERSION = AnotherProject->VERSION();
1;

Note: AnotherProject is located in separate directory, but could be loaded by 'use AnotherProject'. And contain 'our $VERSION="1.00"'.

$ perl Makefile.PL
WARNING: Setting VERSION via file 'lib/project/version.pm' failed
 at /usr/lib64/perl5/5.18.2/ExtUtils/MakeMaker.pm line 599.
Can't parse version 'undef'

Is it possible to pass (get) the version string from another module?

Maybe there is another way to do it, please support me.

When you use VERSION_FROM, ExtUtils::MakeMaker doesn't run the file you point at, it parses it itself and tries to find a version number that way. In this case, that won't work. Using VERSION instead of VERSION_FROM in Makefile.PL and calling the other module from there should work.
