Hi,
Patrick's code does not work since I think I am using c++98. I dont know
how to enable c++11. Anyway for c++98 I wrote the followings(I found on the
internet):
-->
int myints[] = {4000,4000,4000,4000,4000,4000,4000,4000};
const std::vector<int> inputs (myints, myints+sizeof(myints)/sizeof(float));
int myints2[] = {4000,4000,4,4};
const std::vector<int> outputs (myints2,
myints2+sizeof(myints2)/sizeof(float));
-->
makev(8,8,inputs) and makev(4,4,outputs)
It is compiled after "sudo make" command.
But when I wrote "gr_modtool makexml function", I got the following
error(... means I skipped writing these lines).
...
Making GRC bindings for lib/function_impl.cc...
tbi
Error: Can't parse input signature.
tbi
Error: Can't parse output signature.
...
if iosig[inout]['max_ports'] == '-1':
Key error: 'in'
I will post my whole code later.
