Forum: GNU Radio Add ldconfig to build instructions?

Hi,

My problems a few days ago, when switching between branches, simply came
from a missing "sudo ldconfig" at the end of the procedure. Maybe it may 
be
useful to add a more obvious hint? In
http://gnuradio.org/redmine/projects/gnuradio/wiki... it is not
mentioned, and in
http://gnuradio.org/redmine/projects/gnuradio/wiki... only in 
the
broken libtool section.

Of course, the pro should know it, but for beginners this is a PITA, and 
the
error message regarding the python path is very misleading.

I can't validate if this is a (K)Ubuntu problem or a more common cause 
for
trouble...

With best regards


Ralph.

Ralph,

I switch between versions of GNU Radio constantly on my machines and
haven't had to run ldconfig by hand in a long time. It might be a
specific Kubuntu issue (I run Ubuntu) or something about your
environment or shell that you run.

Still, adding a line in there as a hint that if you see a particular
problem to try running ldconfig in the build instructions. Remember,
gnuradio.org is a community page and you can edit it yourself. Just
follow these steps:
http://gnuradio.org/redmine/projects/gnuradio/wiki...

On the other hand, you could look at this link:

OK, I see. The system is relatively unmodified, so it may really be a
Kubuntu issue. People call Windows a dll hell, but Linux obviously can 
grow
similar behavior.

I know, in fact in other projects I add stuff all the time, but I do not
want to add anything that is not useful for many people.

This seems to be the right direction...
