Hi,

I am not sure if the last message went out or not -- I tried to cancel 
it, so I am sending another reply.

It looks like you either have an older source (before 5.10#57, when 
support for CPLEX 10 was added), or you are compiling with the wrong C 
flags (in particular, without -DCPLEX=10). If you have an older source, 
please update to a more recent one, and if you do have a more recent 
source, can you please show me the exact gcc command that was issued 
that generated the above error?

The problem is due to changes in the C API for CPLEX between CPLEX 9 and 
10, and seplex.c needed to be modified for the new API. If you want to 
fix such problems in the future, you would need to look at the 
documentation for the new and old versions (CPLEX 9 and 10 in this 
case), and see how it was changed and modify the code yourself to 
support the new API. In addition, you need to define a new set of 
parameter definitions for the new version in eplex_params.h (the file 
has some instructions on how to do this).

Cheers,

Kish
