Hi,
I have a set of f90 codes and I want to call them from C++. When I compile
f90 file using gfortran and C++ file using g++, I got many link errors like:
~~~~~~~~~~~~~~~~~~~~~~~~~~
NumericalTools.o(.text+0x898):/home/xub/CXX/HISS/NumericalTools.f90:47:
undefined reference to `._gfortran_internal_free'
NumericalTools.o(.text+0x1290):/home/xub/CXX/HISS/NumericalTools.f90:70:
undefined reference to `._gfortran_internal_malloc64'
NumericalTools.o(.text+0x1438):/home/xub/CXX/HISS/NumericalTools.f90:70:
undefined reference to `._gfortran_internal_free'
NumericalTools.o(.text+0x1808): In function `vector_norm2_':
/home/xub/CXX/HISS/NumericalTools.f90:88: undefined reference to
`._gfortran_internal_malloc64'
NumericalTools.o(.text+0x1908):/home/xub/CXX/HISS/NumericalTools.f90:98:
undefined reference to `.sqrt'
NumericalTools.o(.text+0x1954):/home/xub/CXX/HISS/NumericalTools.f90:88:

Could anybody help me? I attached my makefile with this mail.
Thank you
