How_to_square_error

GNU Radio

In my previous installation, still on fedora core 6 I did not experience
this but right now,
when make checking into the src/python directory after having compiled
the
gr-howto-write-a-block stuff

I get this error:

ERROR: test_002_square2_ff (main.qa_howto)

I get this error:

Have you recently compiled and installed the main gnuradio code?
If it passes “make check” then I suggest that you

$ cd …/gr-howto-write-a-block
$ make clean
$ ./bootstrap && ./configure && make && make check

Also, it looks like you’re running all this as root…

Not certain, but this may be a symptom of the linking breakage that was
recently introduced in the trunk (and 3.0.3rc1), by, ahem, me. I’m
fixing that now.
