dpkg default flags break compilation

Hi,

Some more information:

As far as I can tell this only affects jaunty, karmic and lucid. The problem seems to be introduced in 1.14.24ubuntu1 and previous versions of Ubuntu don't contain this version or higher.

To reproduce this problem simply try to compile problems such as LiVES (source package name lives) with a dpkg version higher than 1.14.24ubuntu1. Looking through the build log you should see that LDFLAGS has been set to -Wl,-Bsymbolic-functions. See http://launchpadlibrarian.net/34342772/buildlog_ubuntu-karmic-amd64.lives_1.1.4-1_FULLYBUILT.txt.gz for an example.

While this issue is being resolved, please could someone make sure that the relevant changes don't get synced across to Debian? The last thing we need is lives and other programs on Debian *and* Ubuntu crashing because of a dpkg bug.

Hello, is anybody from ubuntu going to have the courtesy to respond to this ?

Some additional information:

- this bug is now blocking LiVES 1.1.6 and higher from ubuntu, leaving only LiVES 1.1.4 in Karmic. This earlier version had some other unrelated bugs, so it does not give a good impression considering it was the first package version of LiVES in ubuntu.

- versions of LiVES on getdeb.net have been built without the incorrectly set LDFLAGS default. These packages work flawlessly.

- the manpage for dpkg-buildpkg clearly states that the default for LDFLAGS is empty. See http://man.cx/dpkg-buildpackage(1). Therefore the problem is specific to ubuntu and not to dpkg.

Please could someone respond!

This is not a bug, but intentional, see https://wiki.ubuntu.com/CompilerFlags, https://wiki.ubuntu.com/DistCompilerFlags.

It is possible to reset LDFLAGS in the rules file like this:

#!/usr/bin/make -f
LDFLAGS:=
%:
 dh $@

I think this is what you want (although I'm a bit confused by the fact that for some parts of LiVES (weed-plugins) -Wl,-Bsymbolic-functions is set by upstream Makefiles). Sure you can reset CFLAGS the same way if you need to.

If there are significant problems in Karmic package which can demonstrably be solved by rebuilding without -Wl,-Bsymbolic-functions, it's possible to do that. See https://wiki.ubuntu.com/StableReleaseUpdates for the procedure.

I'm reassigning this bug to LiVES because that's where action needs to be taken.

Ok, thanks for the advice. This will be fixed in 1.1.8 which should be uploaded soon.

Fixed in Debian and sync requested to Ubuntu, see LP bug #505914
