Hi Hardik,

I guess you miss GMP and CORE libraries. Please add -lgmp -lcore to LIBPATH.

Best regards,
Laurent

Dear Laurent, 

I have included the Poisson_reconstruction_function as a member of 

my class. 

However, when I try to compile a drive based off the class. I get compiling error: 

I have my makefile as following:

CC = g++

INCPATH = -I $(UMDIR)include/ -I /opt/local/include/

CFLAGS = -g 

LIBPATH = -L$(UMDIR)lib/ -L/opt/local/lib -lCurveGeom -lIBMesher3D -lAnn -lgsl -lgslcblas -lnlopt -lm -lCGAL -lCGAL_Core -lboost_system-mt -lboost_thread-mt

compactsurfmesh: compactsurfmesh.cpp

$(CC) $(INCPATH) $(LIBPATH) $(CFLAGS) $< -o $@

I have CGAL include files in the path (/opt/local/include) 

as well as the dylibs are inlcuded.

Could you point me what am I missing ?

Thanks!

Dear Hardik,

My guess is that your problem comes from the compilation options, probably related to the linear solver (Eigen by default).

If you use CMake, make sure that your CMakeLists.txt looks like poisson_reconstruction_example.cpp example's CMakeLists.txt.
If you do not use CMake, I recommend you to recompile poisson_reconstruction_example.cpp and to cut and paste the compilation options generated by CMake into your own makefile.

Good luck,

Laurent Saboret

Hi Laurent, 

Yes that's true. It is same as 

poisson_reconstruction_example.cpp example.

I am able to compile the example in the directory

examples/Surface_reconstruction_points_3/ however

I am interested in using these function in my own code and 

when I try to compile there it gives the following error. 

Any suggestions towards diagnosing the issue ?

Thanks, 

Hardik Kabaria

Dear Hardik,

The code below seems a cut and paste of CGAL's poisson_reconstruction_example.cpp example.
Does poisson_reconstruction_example.cpp compile properly on your machine?

Best regards,
Laurent Saboret

Hello, 

I am having some issues compiling an example from Surface reconstruction 

part. It'd be great if someone can point out what could be the issue. 

I am using Mac OS 10.8 and cgal 4.4

Warning: port definitions are more than two weeks old, consider updating them by running 'port selfupdate'.
