Hi Xie Yi,
Please try to delete cmake cache and try again:
cd ~/Programs/CGAL-3.6/examples/Surface_reconstruction_points_3
delete CMakeCache.txt
cmake -DCGAL_DIR=$HOME/CGAL-3.6 .
make
Best regards,

Hi, everyone,
after Sebastien helped me, finally I installed taucs successfully. I'm
only
one step away from compiling. I thought at least.
Now I have an error as follow:

I can't find anything about this -ltrue. Has anyone an idea about this?
Thank you.

Thank you Laurent. I found out what the problem was. I was stupid putting
BLAS_LIBRARIES=true and BLAS_LIBRARIES_DIR=/usr/lib/. That's why I got
-ltrue and cannot find it anywhere.
But now I'm facing another problem here:

And still a question. Where can the Lib MKL be found? It's kind of required

Hi,
The errors above mean that the linker did not find blas and lapack.
CMake should have found them and added them to linker parameters.
Did you delete cmake and run again cmake and make as I suggested (see
top of this email)?
