Hi everyone,
It's driving me NUTS! SWIG just won't recognize an argument to my make()
function and hence build fails. I have other nearly identical blocks in the
same module that work without issues.
What exactly generates the *swigPYTHON_wrap.cxx files and how are the argument
lists for the functions determined?
Here is how my make fails:

As can be very, very clearly seen, tx_msg2tag::make(unsigned int) has ONE
parameter (time_increment_factor). Yet SWIG wants to call
gr::petro::tx_msg2tag::make().
I have tried regenerating the file, deleting build directory and starting from
scratch but this error follows me like a nightmare.
Thanks for suggestions!
