compilation HFX - sopt

[marc]

thanks you for the answer manuel.  I left out the comments(#) so I
used this arch file:

CC       = cc
CPP      =
FC       = g95
LD       = g95
AR       = ar -r
DFLAGS   = -D__G95 -D__FFTSG -D__FFTW3 -D__LIBINT
CPPFLAGS =
FCFLAGS  = $(DFLAGS) -ffree-form -O2 -ffast-math -march=opteron -cpp -
I/usr/include
LDFLAGS  = $(FCFLAGS)
LIBPATH  = /home/marc/build/libraries
LIBS     = $(LIBPATH)/lapack-3.2.1/lapack_G95.a \
           $(LIBPATH)/BLAS/blas_G95.a \
           $(LIBPATH)/libint-1.1.2/compilation_folder/lib/libderiv.a \
           $(LIBPATH)/libint-1.1.2/compilation_folder/lib/libint.a \
           $(LIBPATH)/fftw-3.2.1/compilation_folder/lib/libfftw3.a \
           /usr/lib/gcc/x86_64-linux-gnu/4.1.2/32/libstdc++.a \
           /usr/lib/libstdc++.so.6 \
           -lstdc++ -lpthread


OBJECTS_ARCHITECTURE = machine_g95.o

,but now the error is

Warning (158): INTENT(OUT) variable 'e' at (1) is never set
ar: creating /home/marc/build/cp2k/2009-04-27/makefiles/../lib/Linux-
x86-64-g95/sopt/libcp2k_lib.a
ld: cannot find -lstdc++
make[1]: *** [/home/marc/build/cp2k/2009-04-27/makefiles/../exe/Linux-
x86-64-g95/cp2k.sopt] Error 1
make: *** [build] Error 2

So if you say _gxx_personality errors mean that -lstdc++ cannot be
found, this is apparently the same problem now...  no?  Actually I
already encountered this error before (ld: cannot find -lstdc++), so I
tried to "add" it by including the libraries I originally commented
out, but as you can see I get more or less the same error.  So I think
the main problem is that for some reason I don't succeed in letting
cp2k to recognize -lstdc++.  I've looked at other input files but they
all just mention this... as is explained in the README of the
libint_tools.

thank you very much for your comments on this.

ciao

marc
