Well, that means that my test don’t work, since you said that make install
isn’t necesary.
So, let’s start again, what might be a problem?
That’s still impossible to tell from what you’ve written.
I’ve just checked that gr_modtool and the tutorial are correct.
Here’s what I did:
- Create an out-of-tree module
~/tmp % gr_modtool.py create test
Module directory is “./gr-test”.
Creating directory…
Copying howto example…
Unpacking…
Replacing occurences of ‘howto’ to ‘test’… Done.
Use ‘gr_modtool add’ to add a new block to this currently empty module.
- Then, I add a sync-block:
~/tmp% cd gr-test
tmp/gr-test % gr_modtool.py add -t sync square_ff
Operating in directory .
GNU Radio module name identified: test
Code is of type: sync
Block/code identifier: square_ff
Enter valid argument list, including default arguments:
Add Python QA code? [Y/n]
Add C++ QA code? [Y/n] n
Traversing lib…
Adding file ‘square_ff_impl.h’…
Adding file ‘square_ff_impl.cc’…
Adding file ‘square_ff.h’…
Traversing swig…
Editing swig/test_swig.i…
Traversing python…
Adding file ‘qa_square_ff.py’…
Editing python/CMakeLists.txt…
Traversing grc…
Adding file ‘test_square_ff.xml’…
Editing grc/CMakeLists.txt…
- Next, I edit the work() function of the block (this only needs one
line to be changed) to look like this:
Before this is done, the ‘make’ command won’t work!
{
const float *in = (const float *) input_items[0];
float *out = (float *) output_items[0];
for (int i = 0; i < noutput_items; i++) {
out[i] = in[i] * in[i];
}
// Tell runtime system how many output items we produced.
return noutput_items;
}
-
Finally, I edit the file python/qa_square_ff.py such that the test
case contains this:
Before this is done, the ‘make test’ or ‘ctest’ commands won’t work!
def test_001_t (self):
test_data = (1, 2, 3, 4)
correct_res = (1, 4, 9, 16)
sink = gr.vector_sink_f()
self.tb.connect(gr.vector_source_f(test_data), test.square_ff(),
sink)
self.tb.run()
self.assertEqual(sink.data(), correct_res)
Then, I go to the build directory and invoke the make process:
gr-test/build % cmake … # Output omitted
gr-test/build % make # Output omitted
gr-test/build % make test
Running tests…
Test project /home/braun/tmp/gr-test/build
Start 1: test_test
1/2 Test #1: test_test … Passed 0.02 sec
Start 2: qa_square_ff
2/2 Test #2: qa_square_ff … Passed 0.23 sec
100% tests passed, 0 tests failed out of 2
The End.
This entire process took me less than 10 minutes. If you’re taking
longer, you’re wasting time.
Other notes:
- I never installed
- The only editing necessary was three lines in the work() function and
the
test case in qa_square_ff
So go through your module once again, start from scratch and it will
work.
