[Cbc] Linking fails rev2265

Hmm, this is strange. I have a few different theories, but none of them
really fits perfectly. Did you try to see whether libCgl actually contains
those symbols that libCbcSolver is complaining are missing? I was having
this exact problem building with Msys in Windows, but it was a problem with
Cgl, not Cbc, and it shouldn't happen on Linux.
One thing to check---it looks to me like the order in which the libraries
are listed on the link line is wrong, but then I'm not sure why this would
have been working before and suddenly failed. For g++, dependencies should
normally come after the library that depends on them. One thing to try
would be linking in the order:
-lCbcSolver -lCbc -lCgl -lOsiClp -lClpSolver -lClp -lOsi -lCoinUtils
Somethings did change in the configure script between 2264 and 2265, which
could in theory affect linking, but all of this is working on every
platform we test on with our build setup, so it;s hard to imagine why it
would be different for you. I just re-generated the configure scripts for
Cbc and this did result in some changes, which I committed. It's possible
that the scripts got slightly corrupted when I merged some changes from
trunk, but this shouldn't have caused the linking problem you are seeing,
especially since Cbc itself is building properly.
Try with 2268 and if it's still failing, try changing the linking order and
see whether libCgl actually has those symbols. Then we'll go from there.
Cheers,
Ted
