Aha, after using "ff -l dolfin -r quadrature Elastomer2d.form" to generate the Elastomer2d.h file,  the main.cpp can compile. Originally I followed the tutorial at fenics.org, and thought "-r quadrature" was to replace "-l dolfin", and now I understand that it's an independent switch.

Thank you very much for your help.

Best,
Chong Luo

Which version of FFC are you using? Did you compile with the '-l dolfin' option?
