Re: [Discuss-gnuradio] build error: test_gruel.o: undefined reference to symbol 'boost::system::get_system_category()'

[Tom Rondeau]

I have been able to work on this tonight, and I think the solution is that we just needed to be more specific in our LDADDs in a few places. Mostly, it's where we are building programs (noinst_PROGRAMS = xxxx), but we were only passing an LDADD of a few libraries and not everything. I was wondering if there wasn't something more globally we could do, but I'm not sure that's necessary.

Johnathan and I will work on applying these changes where necessary tomorrow. In the meantime, the patch attached to the end of this email was what I needed to do in order to build under Ubuntu 11.04 beta.

Four more errors of the same type (no rule to make xyz). The work

into this more deeply:

I'm really confused why you would need to do this. What OS are you working on again?
