Linker option -Wl,-Bsymbolic-functions

[emmanuel taurel]

Hello Ubuntu team,

I am a user of the libtango8 package available in Ubuntu repository. Since Ubuntu 13.10, this library is built with the option
-Wl,-Bsymbolic-functions. This generates problems for this software. In previous Ubuntu releases, it was not the case and the software worked nicely.

In its source package, in the debian/rules file, there is this line

export DEB_LDFLAGS_MAINT_STRIP="-Wl,-Bsymbolic-functions"

which should prevent the use of this -Wl,-Bsymbolic-functions option when building the package but it seems that it is not true anymore.

Is it a Ubuntu bug?
Is there something we can do with the package developpers?

Any help welcome

Emmanuel

[Impact]

 * The user cannot use anymore tango devices compiled with this version of the libtango8. symptoms are
the Db server refuse to start with the error:
sudo /usr/lib/tango/DataBaseds 2 -ORBendPoint giop:tcp:localhost:10000
main(): arrived
Oups, no class defined in this server. Exiting ...

 * this bugs affect saucy so our users can not upgrade to the saucy distribution.

 * This upload fix the debian/rules. I backported the fix from debian unstable onto 8.0.5+dfsg-3

[Test Case]

Uploaded. Thank you!

I made two trivial changes:

1. I dropped the change to debian/gbp.conf, since the SRU must include "no other unrelated changes" according to the policy.
2. I ran "update-maintainer" to update the Maintainer field according to https://wiki.ubuntu.com/DebianMaintainerField.

The next step is for the SRU team to review this, and assuming that they accept it a final verification step from -proposed will be needed.
