Hi,
I am trying to use *gr::io_signature::makev* for my output signature in my
bar_impl.cc
bar_impl::bar_impl(int offset, int freq)
: gr::block("bar",
gr::io_signature::make(2, 2, sizeof(gr_complex)),
* gr::io_signature::makev(4, 4, out_vect))*
For that in the header I did following in the header bar_impl.h
*const std::vector<int> out_vect = {sizeof(gr_complex), sizeof(gr_complex),
sizeof(float), sizeof(float)};*
It compiles but when I do gr_modtool makexml, it throws this error
john@john-Precision-5510:~/nuradio/src/gr-fist$ gr_modtool makexml bar
GNU Radio module name identified: fist
Warning: This is an experimental feature. Don't expect any magic.

Error: Can't parse output signature.

KeyError: 'out'
Need some help :)
