Hi all,
I'm trying to compile an example from /demo/documented/poisson/cpp with
>g++ -I /usr/include/eigen3 main.cpp -o Poisson
but I get a bunch of lines starting with
/tmp/ccsvzILI.o: In function `main':
main.cpp:(.text+0xae): undefined reference to
`dolfin::Constant::Constant(double)'
main.cpp:(.text+0x10f): undefined reference to
`dolfin::DirichletBC::DirichletBC(dolfin::FunctionSpace const&,
dolfin::GenericFunction const&, dolfin::SubDomain const&,
std::basic_string<char, std::char_traits<char>, std::allocator<char> >, bool)'
main.cpp:(.text+0x19e): undefined reference to
`dolfin::CoefficientAssigner::operator=(dolfin::GenericFunction const&)'
...
and if I compile with
>g++ main.cpp -o Poisson
I get
In file included from /usr/include/dolfin/multistage/dolfin_multistage.h:8:0,
from /usr/include/dolfin.h:21,
from main.cpp:34:
/usr/include/dolfin/multistage/PointIntegralSolver.h:25:23: fatal error:
Eigen/Dense: Ficheiro ou directoria inexistente
compilation terminated.
I'm using FEniCS 1.3.0, Ubuntu 12.04.4 and dolfin.h is at /usr/include/dolfin.h
Can anyone please help me?
Thanks,
Paulo
