-assume noold_ldout_format for GNU

[nachiket k]

Hi,
copygb2 has dependency on modfiles genereated from library g2

Makefile parameters for g2 were

Original for intel

DEFS=-DLINUX
FC=ftn
CC=cc
CPP=CC -P
MODDIR=../g2/lib/temp/incmod/g2_4

FFLAGS=-O3 -g  -assume noold_ldout_format -module $(MODDIR)


Changed GNU

DEFS=-DLINUX
FC=gfortran
CC=gcc
CPP=cpp -P
MODDIR=../lib/incmod/g2_4

FFLAGS=-O3 -g #-freal-4-real-8 -J $(MODDIR)
CFLAGS=-O3 -g $(DEFS) $(INCDIR) -D__64BIT__

(I have tried it with various flags just to sure which works here but
ultimately copygb2 is still failing)
Compilation of g2 was completed without errors.


In compilation of copygb2

        gfortran -c $(INCS) $(FOPTS) $*.f
clean:
        -rm -f $(OBJS)


(Commented flags are some of the ones I tried which did not work )


>gfortran -c -I../lib/g2_d/ -freal-4-real-8 copygb2.f

copygb2.f:1074:72:

      &                 IBBI,LBI,FBI,GBI,IRET)
                                                                        1
Warning: Type mismatch in argument ‘ngdt1’ at (1); passed REAL(8) to
INTEGER(4)
copygb2.f:776:20:

           CALL CPGB1(LG1,LX1,M1,
                    1
Error: Explicit interface required for ‘cpgb1’ at (1): target argument


I have tried to compile CPGB1 as separate file and rest of copygb as
separate file
I am able to generate .o files but link time I get lot of undefined
references (-I../lib/g2_d did not work )

As I am not sure which source is causing problem I though I should do
literal translation of flags from intel to GNU


If you have any idea on how to resolve this issue please let me know of
link to resource that might help me in this regard

Thanks,
Nachiket
