Make error

Fresh SVN checkout as of this morning, into a new directory (r5734).
Ubuntu Edgy, everything’s upgraded to its newest version, more or less
along the lines of the install guide that mdickens and I put together on
the trac.

  1. ./configure spits out some stderr messages about
    /etc/ld.so.conf.d/*.conf not existing. Is this expected? The next line
    is “GNU/Linux ld.so”, so I suspect it is just doing detection, but the
    test could probably be fixed to avoid the stderr output.

  2. Error when compiling mblock

I swear sending an email to a support list reduces the MTTR of bugs by a
factor of 100!

That weird linking bug is still around somewhere – I had done a make
distclean in the old directory but ended up having to go purge all of
/usr/local/lib to get the mblock to compile.

There is a ‘make uninstall’ target that removes everything that was
installed by GNU Radio (including all the header files, docs, etc.) This
is a useful way to purge all traces of GNU Radio from the system before
upgrading from a source install.

If so, all of this is probably a result of the broken version of
libtool that Debian/Ubuntu ships.

Yes; sorry that was in the original post but not in the reply.

$ cat /etc/ld.so.conf
/usr/local/lib/

include /etc/ld.so.conf.d/*.conf
/usr/lib/atlas

Is there an ordering problem? That’s the only difference I can think of
(I’d test but I’m not sure how to reproduce the bug).
