Gr-howto-write-a-block build fails

GNU Radio
1

Dear List,

I’m looking to write c++ gnuradio blocks using the
gr-howto-write-a-block code that comes with gnuradio. Unfortunately,
when I do the build with the existing code, the tests fail. Has anyone
else seen this?
I’m running Ubuntu 12.10.

I haven’t (and it shouldn’t fail). Comments:

  1. Don’t use ‘sudo’ for cmake and make test, unless really necessary.
  2. You can build gr-howto-… for educational purposes, but I strongly
    recommend using gr-modtool instead.
  3. In general, if a test fails, use ‘ctest -V -R <+REGEX+>’ to obtain
    the output of the failed test.
    Provide that in any email here.

It appears that qa_howto failed because of a missing module.

It looks like you’re just missing where libgnuradio-core is installed.
Make
sure you installed GNU Radio, and then set LD_LIBRARY_PATH to point to
the
location of the installed libraries (/usr/local/lib by default unless
you’ve changed the install prefix).

  1. Thank you for your advice. I went through and changed ownership to my
    user name, and I will only use sudo for installation.
  2. I still want to figure out why gr-howto- is failing, but I have
    installed gr-modtool and will be using it.
    Does anyone know of a good tutorial for this package? I wrote my work
    function, but I’m not sure how to write a test.
  3. I tried using ctest and got the following error:
