mip_test fails with CBC trunk version

Reported by: Alpar Juttner Owned by: Balazs Dezso

Component: core Version: hg main

Description

mip_test.cc fails with the current trunk version of CBC (SVN trunk, rev 1234).

There is also a trivial bug in formatting the corresponding error message. This problem is fixed in the attached patch, [860cdc983618].

Finally, compiling LEMON with CBC still emits a warning. For me, it looks like a real problem in CBC.

I have checked the bug, and it is in the cbc package. I forwarded it to the bug tracker system of cbc package. Fortunately, the 2.3 stable branch works fine.

I added a new patch [38b69b5d33df] to remove dependency on OsiCbc? package.

In my opinion, if the existing patches are applied on the trunk, we can resolve this issue as "invalid" or "wontfix".

[860cdc983618] and [38b69b5d33df] has been rebased and added to both the main and the 1.1 branches. See [1f08e846df29] and [36857046492b].

Balazs,

Could you check the status of this ticket? Is there any news from the Cbc's side?

I've just tested with CBC 2.5.0 and this release doesn't work. CBC devs probably failed to fix it in the SVN before release. The bugreport Balazs issued (https://projects.coin-or.org/Cbc/ticket/83) is still open and seems untouched, which makes me a bit disappointed with the CBC developers.

mip_test.cc passes with CBC svn version 1867 (around Feb. 2013), thus I think this ticket is obsolete now.
