Hi Xie Yi,

The output of "make VERBOSE=1" shows that libPS_demo_poisson_plugin.so 
is not linked with METIS (a library required by TAUCS).

Please run again cmake-gui in demo/Surface_reconstruction_points_3 and 
set the next variables exactly like in 
examples/Surface_reconstruction_points_3:

BLAS_DEFINITIONS=-DBLAS_USE_F2C
BLAS_LIBRARIES=/usr/local/lib/libf77blas.a;/usr/local/lib/libcblas.a;/usr/local/lib/libatlas.a;/usr/local/lib/libg2c.so
LAPACK_DEFINITIONS=-DLAPACK_USE_F2C
LAPACK_LIBRARIES=/usr/local/lib/liblapack.a;/usr/local/lib/libg2c.so
TAUCS_INCLUDE_DIR=/usr/local/include
TAUCS_LIBRARIES=/usr/local/lib/libtaucs.a;/usr/local/lib/libmetis.a


Regards,
Laurent S.
