[Coin-discuss] Cbc ampl interface under OS/X Tiger

[Kipp Martin]

Hi:

I don't think the Cbc/ASL problem is a Mac OS X only problem.  I am running

https://projects.coin-or.org/svn/Cbc/stable/2.0/Cbc
https://projects.coin-or.org/svn/BuildTools/ThirdParty/ASL/trunk

using Cywin/gcc

and getting an

undefined reference to _sys_Details

My colleague Jun Ma is getting the same error with Mingw/gcc

I think there may be a Cbc/ASL problem.

Regards,
