I've had a similar problem when I generated files for my own module
using the gr_modtool and then copied some existing code by replacing the
file(s) that gr_modtool generates. It turns out I had overlooked that
the new "my_block" name needs to be changed in several places, like the
namespace declaration, the #include compiler directive, and the
conditional #ifndef INCLUDED ... directives. Once I updated that
correctly the AttributeError got resolved.

Dear All,
I am trying to make an out of tree module by following the tutorial on
Gnu radio website. I can write simple blocks in C++, compile it and
install it to it usable in Gnuradio company.
But for some complex block, I want to implement them based on the
gnuradio build-in blocks, for example, clock_recovery_mm_ff. So I make
a new block in my out-of-tree module and try to first "copy" the
build-in block into my out-of-tree module.
I changed the following 4 files in my OOT module to match the
corresponding files of the build-in block:
lib/my_block_impl.cc
lib/my_block_impl.h
include/my_block.h
grc/my_block.xml
In each file, I changed all the "clock_recovery_mm_ff" into "my_block".
I can successfully make and install the block without error and
warring. But when I try to run the grc graph, an error happens.
AttributeError: 'module' object has no attribute 'my_block'.
Anyone can tell me what I should do to correct this error? Is there
any other files I should change?
When I make simple blocks by myself, I only change this 4 files and it
works.
Best regards,
Su Li
