Question about adding new files and making autotools happy

GNU Radio

Hi all,
I’m working with GNUradio 3.2.2 on an Ubuntu 8.04 x86 box. I’m in the
process of making some modifications to the source that builds libusrp,
and
part of these modifications includes adding some new files under
usrp/host/lib/legacy, where all the RF daughterboard code lives. This
seemed easy enough: add my files (foo.cc and foo.h) to this directory,
update the Makefile.am located in usrp/host/lib/legacy so that the
libusrp_la_common_SOURCES included foo.cc, update include_HEADERS so
that it
included foo.h, and re-run a top-level configure. But I’m still missing
something, because the Makefile for the usrp/host/lib/legacy directory
that
gets generated from the configure process doesn’t include my new files,
and
thus my new code never get built.

I’m a complete noob with autotools, and I’m probably making some silly
mistake, but I’m at a loss as to what that could be. Couldn’t find much
on
the mailing list or internet to point me down the right path. Anybody
got
any ideas?

Thanks for the bandwidth.

./bootstrap && ./configure

Should work

Ahh…I didn’t think bootstrapping first was necessary if re-building (I
had
assumed that configure took care of aggregating the file lists, but this
obviously is wrong). Indeed, upon first bootstrapping, configure
produces a
Makefile with my files included. Thanks much Eric.

Amongst other things, bootstrap runs automake, which builds the
Makefile.in’s from the Makefile.am’s.

configure generates the Makefile’s from the Makefile.in’s

Glad to hear it worked!
