[Discuss-gnuradio] ImportError problem for make check

[Andy_Long]

Hi everybody,

I just cant figure this out, so I have to ask here: I am trying to import my
own block, but when running "make check", I get an ImportError. It is just a
simple test that I only change the name of "howto" module as "myblock" and
keep the same for the rest part of code. 

Then I modify Makefile.swig.gen and Makefile.am by searching/replacing all
ocurrences of 'howto' with "myblock".   Should I do some addition changes in
this step?

After that, under the directory /gnuradio/gr-howto-write-a-block, I run 
./bootstrap
./configures
make
make check

I got the ImportError as below:




address@hidden:~/Desktop/myblock$ make check

Any help will be appreciated

Thank you
