[Discuss-gnuradio] libtool error with howto example (_howto.la)

[Vijay Ramasami]

Hi,

Please bear with me as I am new to gnuradio (and autotools in
general). I am catching up ... Gnuradio version 3.0.3 as such compiles
fine on my system (Cygwin on XP), and I am able to run all the
examples. But, I am having a problem getting the howto example to
work.

I have setup a new directory structure under the gnuradio (ver 3.0.3)
main directory, and copied the howto example files to that directory
(as per the article on creating a new block).

I added a new M4 file in config following the examples used for other
directories, ran "bootstrap", "configure", and then "make" in the
gnuradio subdirectory. When I do this, I am getting the following
error from libtool:

Try `libtool --help --mode=link' for more information.

The problem is here:
libtool: link: libtool library `_howto.la' must begin with `lib'

Can someone please provide a clue as to what might be wrong ? I
greatly appreciate your time.

Thanks,
Vijay.
