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
