Hi Barry,
For the code without PETSc, the rules used to compile the code with CGAL is
DLIB = -lstdc++ -lmetis -lm -L/usr/local/lib -rdynamic
/usr/local/lib/libmpfr.so /usr/local/lib/libgmp.so
/usr/local/lib/libCGAL_ImageIO.so.11.0.1
/usr/local/lib/libCGAL.so.11.0.1 /usr/local/lib/libboost_thread.so
/usr/local/lib/libboost_system.so -lpthread -lGLU -lGL -lX11 -lXext -lz
/usr/local/lib/libCGAL_ImageIO.so.11.0.1
/usr/local/lib/libCGAL.so.11.0.1 /usr/local/lib/libboost_thread.so
/usr/local/lib/libboost_system.so -lpthread -lGLU -lGL -lX11 -lXext -lz
/usr/local/lib/libmpfr.so /usr/local/lib/libgmp.so
/usr/local/lib/libboost_thread.so /usr/local/lib/libboost_system.so
-lpthread -Wl,-rpath,/usr/local/lib
FFLAGS = -O3 -I$(LIS_INC)
CXXFLAGS = -std=c++11 -O3 -I$(LIS_INC)
However, after adding these to the makefile using PETSc, I got error
telling me that all the petsc include files cannot be found.
../../solver/solver_snes_common.F90:27:0: fatal error: petscversion.h:
No such \
file or directory
#include <petscversion.h>
../../solver/solver_snes_common.F90:27:0: fatal error: petscversion.h:
No such \
file or directory
#include <petscversion.h>
Similar for other head files. However, If I change the file path to the
the full path, the code cannot compiled. Does the rule I use destroy the
PETSc relative path/
The make commands I use is
executable: $(SOURCES) chkopts
-${FLINKER} $(FFLAGS) $(FPPFLAGS) $(CPPFLAGS) -o executable.out
$(SOURCES) ${PETSC_LIB} ${LIS_LIB} ${DLIB}
%.o:%.F90
$(FLINKER) $(FFLAGS) $(FPPFLAGS) -c -frounding-math $< -o $@
%.o:%.cpp
$(CLINKER) $(CXXFLAGS) $(CPPFLAGS) -c -frounding-math $< -o $@
Thanks,
Danyang

You need to determine exactly what flags are passed to the C++ compiler for your
compile that works and make sure those same flags are used in "PETSc version"
of the makefile. You could add the flags directly to the rule
%.o:%.cpp
$(CLINKER) $(CXXFLAGS) $(CPPFLAGS) -c -frounding-math $< -o $@

Hi All,
My code needs to link to an external C++ library (CGAL). The code is written in
Fortran and I have already written interface to let Fortran call C++ function.
For the sequential version without PETSc, it can be compiled without problem
using the following makefile. The parallel version without CGAL can also be
compiled successfully. However, when I tried to use PETSc together with CGAL
library, I cannot compile the code. My questions is: How can I modify the
makefile? Do I need to reconfigure PETSc with special flags? All the makefile
samples are shown below.
