[OBOE] OBOE - g2c deprecated in gcc-4.4 (used in Ubuntu 9.10 - karmic)

[Berit Løfstedt]

Hi Nidhi ,

I was very pleased to see OBOE as part of COIN as I could really use the MCF algorithm of Babonneau for a network design heuristic. However, I am finding it very difficult to get the source code to actually execute and I am hoping you may be able to help me. I have been following your instructions for Ubuntu, but I probably have a newer version.

First, in AccpmLASolve.C, line111 , the 4. argument &A(0,0) raises a casting problem, which can be resolved by changing to A.addr() - According to http://lapackpp.sourceforge.net/html/classLaGenMatDouble.html#c700d02217d67ef7a2a5810c59e04a4e

After this "make" and "make install" runs smoothly, but make check fails.

Firstly, libtool is installed locally in the OBOE library and is an older version. Hence some of the commands are unknown.

The main problem is however that the linker cannot find g2c.
In gcc-4.4 g2c is deprecated (see https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/477278  )

Now gfortran is used and it does not contain g2c. libg2c0 can be found as a package, but linking it staticly actually requires building libg2c from scratch. As of now I have spent about 3 working days getting OBOE to work properly and I am wondering whether I could simply use gfortran? I suspect that the dependency to g2c migt have swapped to gfortran as it is blas, lapack and lapackcpp which has the dependendy. These source codes have new releases (the current version of lapackcpp is 2.5.2 which compiles neatly with gcc-4.4) and hence are probably not dependent on g2c. Do other parts of the code have g2c dependencies?

Which version of Ubuntu was the wiki instruction made for? Downgrading might solve my problems :-)
