Dear Yves,
Yes, that was the problem, thank you.
Now I'm still looking at the tutorial about Thermo-elastic and electrical
coupling (with MatLab it helped a lot and it was very clear) and adding the
code the single line
>> getfem::mesh mesh;
gives me theese errors:
C:\Users\cambi\AppData\Local\Temp\ccsXaSdU.o prova1.cpp:(.text+0x285):
undefined reference to `getfem::mesh::mesh(std::string)'
C:\Users\cambi\AppData\Local\Temp\ccsXaSdU.o
prova1.cpp:(.text$_ZN5bgeot15block_allocator7dec_refEj[_ZN5bgeot15block_allocator7dec_refEj]+0x62):

I have to say I'm pretty new to C++, so I'm very confused: shouldn't this
line just define the existence of the mesh? Thank you very much for your
help and your time, it's much appreciated.
Best Regards,
Nicolò Cambiaso
