Try this instead:
const std::vector<int> inputs{4000,4000,4000,4000,4000,4000,4000,4000};
and make sure you compile with c++11 enabled.

Subject: Re: [Discuss-gnuradio] GNURadio OOT vector input/output with different
size
Hi,
I dont have any background about C++. So I could not generate the
std::vector<int> with the desired content and could not fınd anything on the
internet.
const std::vector<int> inputs[] = {4000,4000,4000,4000,4000,4000,4000,4000};
does not work. I am getting the following error:
"conversion from 'int' to non-scalar type 'std::vector<int>' requested"

Hi Ali,
I think this should also work, shouldn't it?
no, that's why I explained what you need to do (use makev).
Does this part need to be changed since I am working with the vectors?
No, not really. The vectors are still only consecutive numbers in memory.
Best regards,
Marcus

Hi,
1- Actually I am using the followings
make(8,8,1000*sizeof(float))
make3(4,4,1000*sizeof(float),1000*sizeof(float),4*sizeof(float))
I think this should also work, shouldn't it?
2- Under the general work function I am using the followings:
const float *in1 = (const float *) input_items[0]
...
float *out1 = (float *) output_items[0]
Does this part need to be changed since I am working with the vectors?
Thanks,
Ali

Hi Ali,
So, you want one block with:
* 8 inputs, itemsize0…7 = 1000*4B = 4000B
* 4 outputs, itemsize0=itemsize1=4000B, itemsize2=itemsize3=16B
Correct?
You need to generate two std::vector<int> with content
{4000,4000,4000,4000,4000,4000,4000,4000}
and
{4000,4000,16,16}
respectively, and use gr::io_signature::makev(int min_streams, int max_streams,
vector) to generate the io_signatures[1] that you use in your block's
constructor. The question whether your block should be a general, or a sync
block, is independent from the item sizes of the in and outputs, but depends on
whether there's always a fixed ratio of produced output items to consumed input
items, as explained in [2].
Best regards,
Marcus

Hi to all,
I want to design my own OOT module with the following I/O:
8 inputs (length of 1000 and each element is type of float)
2 outputs (length of 1000 and each element is type of float)
2 outputs (length of 4 and each element is type of float)
I used general type block but I could not get the desired outputs. Do you
suggest other type of blocks? Is there any example similar to this work that I
can study on? Can you suggest a module name or a link?
Best,
Ali
