CGAL users discussion list

Ok, here's the output. I changed the names of all fortran function calls from
C++ to the format that worked with my own make file (without CGAL),
{moduleName}_{functionName}_

make VERBOSE=1; output:

===================================================
The "undefined references" occur when the main program local_clib.cpp tries
to call the fortran 90 subroutines.

===================================================
Just for reference, here's my Makefile that worked cross compiling C++ and
Fortran90 using boost libraries, but without CGAL:

# Linker:
LN = g++
# F90 compiler
#F90 = pgf90
F90 = gfortran
# C++ compiler
CPP = g++

# Boost libraries:
CPPLIB = -L/homes/metogra/spenny/boost_1_44_0/stage/lib -lboost_date_time
# Fortran run time libraries:
F90LIB = -L/misc/local64/pgi-9.0.2/linux86-64/9.0-2/lib -lpgf90 -lpgf90_rpm1
-lpgf902 -lpgf90rtl -lpgftnrtl -lnspgc -lpgc -lrt -lpthread -lm -lgcc -lc
-lgcc
CPPINC = -I/homes/metogra/spenny/boost_1_44_0
F90INC =

local_exe.x : letkfio.o local_clib.o
        $(LN) $? -o $@  $(F90LIB) $(CPPLIB) $(CPPINC)

clean :
        rm *.o *.x *.mod

local_clib.o : letkfio.o local_clib.cpp
        $(CPP) $(CPPLIB) $? -c $(CPPINC)
letkfio.o : letkfio.f90
        $(F90) $(F90LIB) $? -c $(F90INC)
