cfx5mkext failed at eval
 

Hey,

I am using running CFX on ubuntu 12.04. I am trying to use a junction box routine to define a momentum source. I used the following code and tried to compile the fortran subroutine as given in the tutorial 19,

! system ("cfx5mkext MomentumSource.F") == 0 or die "cfx5mkext failed";

But, I get an error pop up which says,

ERROR
CCL parser failed with message:
Perl Syntax errors detected:
cfx5mkext failed at (eval 15) line 1

I am new to UDFs, any idea where I might be erring ?
Thanks in advance :)
