The error code is telling you what you need to know; your C++ is
invalid. You can't declare variables inside the call to cons(). Use the
converter functions to convert 'out' to a PMT (same with the second PMT)
or use the constructor notation and skip the 'const'.
This is unrelated to PMT or even GNU Radio. I'm sure googling for the
gcc error message would have given you at least some response.
Cheers,
