Forum: GNU Radio gr-howto-write-a-block build fails

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.

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:

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).
