compiling the scipsuit (linux)

Question

I downloaded the scipsuit and tried to `make' it. Here is the error I get. Any idea how to resolve it?

make[2]: Leaving directory `/shared/shelley/khashab2/SCIP/extracted/zimpl-3.3.2'

Here is the GCC version:

[khashab2@austen extracted]$ gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11)

Answer 1

Your version of GCC is too old. You may either use a newer version (recommended), or try compiling with LEGACY=true. This will disable the rational solving mode.
