Hi Cajus et al
You say "I don't think that this is a linker issue, because stuff builds fine with the unmodified Makefile.in files." I don't really understand what you are saying here, especially after you've said "I've some minor modifications in a couple of Makefile.am files where the bootstrap produces a non buildable qpid-cpp. If I ignore the .am"

As I said previously I ended up patching the Makefile.am to include explicit linkage information and (with my Linux Mint 12 box at any rate) running bootstrap, configure, make then gives a clean build (I've not tried 0.14 yet).

The reason I cite it being a linker issue is because the patch I had to put in place was consistent with adding explicit "-l<some library>" to a load of Makefile.am

This was all related to a linker error that I was getting, which seems to have generated a lot of Internet traffic including this link http://fedoraproject.org/wiki/UnderstandingDSOLinkChange which set me on the track of getting something that worked for me.

To be honest I can't believe that nobody else has commented on this, we surely can't be the only people who've been trying to get qpid to run on Ubuntu 11.10 (or derivatives such as Mint 12) also I'm surprised it's not cropped up for people using other distros as the fedora link above describes similar issues for other projects that definitely relate to changes that have been made to the default behaviour of ld in recent versions of gcc.

I've not had any comments on the Jira other than from Cajus so I don't know at all whether this is seen as a problem.

At the moment my broker really is a patchy qpid :-)

Although this thread turns a month now, I'd like to comment on it ;-)

The build problems are reproducible from the moment you start to let whatever script recreate the autotools related files of the qpid-cpp package. In the Debian packages, I've some minor modifications in a couple of Makefile.am files where the bootstrap produces a non buildable qpid-cpp. If I ignore the .am files and do some hackish Makefile.in modifications, the build and the tests work fine.

For the upcoming 0.14 the problem still exists, and it is not possible to do a clean build with the modifications. Additional "fix-inplicit-linking" modifications are needed to get a clean bulid - but most of the tests related to SASL fail in this case.

I don't think that this is a linker issue, because stuff builds fine with the unmodified Makefile.in files. And they do not really differ in the linker options that I can see an error there...

The question is: how do I regenerate the autotools files in a way that it just works?

I *think" I've cracked this......
I built everything fresh and added the patches fresh and make install
seemed to then work. I was a bit baffled then realised my shell had
some environment variables set.

My suspicion is that I needed to have
export LDFLAGS=-L`dirname $(pwd)`/cpp/src/.libs

set before calling ./bootstrap
This would have been the case for the make that worked so it's got me
wondering.

I'll try again from absolute scratch tomorrow to see if I can get a
systematic build (I must be mad uninstalling a working build, but I
really want to be able to do a reproducible build)

I'll keep you posted.

Hi again,
I've now got a bit further forward and have got make to work. I had an awful lot of problems due to the explicit linkage issue that seems to be caused by recent versions of gcc (I'm using 4.6.1)

From a virgin qpid-0.12.tar.gz download I had to

cd qpid-0.12/cpp
patch -p1 < ../../fixed_unused.patch
patch -p1 < ../../fix-explicit-link-problem.patch
./bootstrap
./configure
make

I've attached the patches, the first of these is Cajus Pollmeier's patch the fix-explicit-link-problem.patch is a patch I've put together for a number of Makefile.am files to add the necessary explicit linkage.

So far this seems to give me a make that completes and I can run qpidd in qpid-0.12/cpp/src OK but unfortunately sudo make install fails with the errors below.

Previously when I had libtool linkage errors with make install I did:

export LDFLAGS=-L`dirname $(pwd)`/cpp/src/.libs

which used to work on my old Ubuntu 9.1 box. Unfortunately this doesn't seem to work on my Mint 12 box running gcc version 4.6.1

I'd really appreciate any help, this is really bugging me now - I don't think this is necessarily a qpid problem per se, but given what I'm seeing I'd be surprised if anyone has managed to build on Ubuntu 11.10 without a fight - am I wrong, have I missed something obvious????

heeeellllppppp!!!!

Hi again all, I've done a bit of Googling on this and it appears that this behaviour has something to do with changes that have been made to the linker behaviour http://fedoraproject.org/wiki/UnderstandingDSOLinkChange (this is a Fedora page and I'm using Mint but the symptoms seem identical).

Has anyone else seen this and got a decent workaround?

I'll have a play and see if I can hack the makefile, at a guess it probably just needs an *explicit* -lboost_program_options added to the right place in the Makefile my problem is that I'm clueless about automake, so if it doesn't "just work" I'm working blind. At a guess some work is needed to the automake generation templates to fix this properly, but I wouldn't know where to begin.

I suspect that I'm not the only one who's going to be seeing this issue (my Mint 12 box uses gcc version 4.6.1) given the description in the Fedora page.

I'd appreciate any thoughts/tips
cheers,
Frase
