[GiNaC-list] Compilation

[Patrick Schulz]

Hello Pedro,

that is more a matter of your compiler and your system than of GiNaC.
Since you are on ubunte and ginac.h is already in /usr/include/..., the 
program can be compiled with

     g++ program.cpp -lginac

(-lginac tells the linker to load the library).

However, your program has an error, since poly is not defined. Add

ex poly;

above your for-loop, then it runs fine.

Kind regards,

Patrick
