Mblock make failure under Cygwin

GNU Radio
1

I reinstalled gnuradio under cygwin from scratch, using the latest
subversion trunk.
Following http://gnuradio.org/trac/wiki/CygwinInstallMain, I
built/installed a minimal gnuradio setup, and that worked fine.

Then I tried to add a few extra parts of gnuradio (usrp, mblock, gpio,
etc.) and ran into what looks like a linker problem involving
inband/mblock code (possibly also involving boost?)

build log & build error file are attached…any ideas/workarounds?

Bump in case my email got lost in the weekend shuffle. The first error
encountered is:

.libs/qa_inband_usrp_server.o: In function
_ZN5boost6detail17sp_counted_impl_pI12qa_alloc_topE11get_deleterERKSt9type_info': /usr/include/boost-1_33_1/boost/detail/sp_counted_impl.hpp:(.text+0x9b): undefined reference to mb_mblock::~mb_mblock()’

Any thoughts?

It looks like you are missing a patch (attachment:"makefiles6975.patch,
listed on the Cywin wiki page) needed to include the mblock library in
the
link of qa_inband_usrp_server.

Thanks Don.

FYI, we haven’t applied this patch to the trunk because the real
problem is with libtool under cygwin. The patch replicates
information (always a bad idea) that libtool already knows on all
other systems.

Thanks for the reply. I did in fact try to apply both patches that are
mentioned on the page, but I think I may have done so incorrectly:

I suspect that they’re out of date.

We merged a lot of inband stuff into the trunk about a month ago.

Are the patches out of date, or am I doing something wrong? I am not
very familiar with the patch command.

Good news: libtool 2.2.2 is now available on Cygwin and seems to handle
the
interlibrary dependencies.

Bad news: (a) using the new libtool requires running bootstrap (to get
new
ltmain.sh, libtool.m4, …?), so it still requires a patch (to add
bootstrap) to work with the current release; and (b) autoconf (and/or
libtoolize?) produce a number of warnings, such as “LT_OUTPUT was called
before LT_LANG”. (I think there are some compatibility issues, but I
haven’t found any simple documentation on them yet.)

Unknowns: I don’t know if libtool 2.x runs on MinGW, and I haven’t
tried it
on Debian (to see if it gets the same warning messages).

That’s great news. FWIW, the next release will have bootstrap
included in the tarballs.

This patch is needed for the 3.1.2 release, not for the svn version.

patching file mblock/src/lib/Makefile.am
Hunk #1 succeeded at 131 (offset 1 line).

Eric is correct; this patch worked at svn revision 6975, but doesn’t
work
now because of updates to the trunk. But if you look at the listing of
the
patch, you can see that it adds three lines to
usrp/host/lib/inband/Makefile.am, one of which has been added in the
trunk
since the patch was developed. The quickest solution is to edit the
file by
hand to include lines added by the patch. I should get around to
producing
an updated patch in a day or two.
