Dear Ambros,

Thank you very much for your quick response. Could you please let me know
how I should use this patch file ?

Secondly, I have also been trying to port my SCIP based code to a server
with gcc 4.8.0. Here I seem to get a different error during linking.
I compiled using "make LPS=cpx GMP=false ZLIB=false READLINE=false" and
this is the error I got:

** Build complete.

** Enter "make test" to solve a number of easy instances in order to verify
that SCIP runs correctly.

Any suggestions on how I could fix this ?

Thank you very much,
