I have a perl module : abcUtil.pm which has a subroutine check : 
package abc::abcUtil;
require "common.pl";
sub check {
   ..
   PERL_DEBUG("");
   # PERL_DEBUG is in common.pl
   ..
}

When I execute this , it works fine, But when i use this pm in another perl: 
require "common.pl";
use abc::abcUtil;
sub func {
    abc::abcUtil::check();
}

Here, if I call func(), I get this error : "Undefined subroutine &abc::abcUtil::PERL_DEBUG .." There are other direct occurrences of PERL_DEBUG in this perl file which are working fine. What might be wrong ? Thanks -------------- I updated the code in the 2nd file as follows: 
#require "common.pl";
use abc::abcUtil;
sub func {
    abc::abcUtil::check();
}

Basically removed the use of common.pl. Kept the abcUtil file as unchanged. Now it worked. But I can't keep it this way as have to use this common file. Is it some conflict due to the use of 'require "common.pl" ' in both the files?
