I have a perl script (MyTest.pl) that includes (use) two modules (MyA.pm and MyB.pm). The problem I have is that module A also have to include Module B, but this doesn't seem to work as is already has been included in the .pl file.
MyTest.pl
use MyA;
use MyB;
print hello(); # defined in MyB
MyA.pm
use MyB;
print hello(); # defined in MyB
perl states that the subroutine hello is undefined when called from MyA.pm. From what I can grasp it seems like the use only works where it is used (ha!) the first time.
Any clues?
You don't show us an import method for MyB or tell us if it inherits the import method of a standard module like Exporter.
Without an import method, the MyB::hello subroutine can't be aliased into the Main or MyA namespaces.
Your 2 choices are to do the import or to use the full name of MyB::hello.
Edit:
Hmm, I also notice that you're not using a package name in MyA. Are your modules all using the Main namespace as their personal litter box?
