New description:

 Hi Beata,

 negInfinity is *declared* as an extern variable in asl.h, one of the
 include files for the Ampl Solver Library (ASL) used throughout Couenne.
 That variable is *defined* in mach.c, again from the ASL library. It
 should be available in amplsolver.a. See ThirdParty/ASL and documentation
 therein. In principle, if the ASL library is linked with Couenne, all
 should be OK. Can you tell something more about the system where you have
 installed Couenne?

 Thanks,
 Pietro


 Hi, I am trying to use COIN-OR with Couenne from an external application.
 I have configured, built and installed COIN-OR according to the
 instructions, and all that was reported as successful. However, when I
 invoke my external application, I get the following:

    (E) Failed to load 'libMyApp.so'.
 /home/bss/COIN_OS/lib/libCouenne.so.0: undefined symbol: negInfinity

 Could you help me resolve that?

 Thanks,
 Beata
