    Subject: COmpiling individual link of G90 on IBM RS/6000
    Status: R
    
    The bldg90 script that comes with the RS 6000 version of Gaussian 90
    seems to be only capable of compiling the entire program, not individual
    overlays(say l101, l302, etc.).  How do you compile and link individual
    overlays?

1.  You can use the file g90/bsd/g90.make to build individual links:

    cd $g90root/g90

    make -f bsd/g90.make l302.exe

    will recompile and relink l302, assuming that l302.F is more recent
    than l302.exe.

2.  If you are debugging your own link in your own directory, you can start
    from the sample makefile given below.  It ensures that the compiler
    flags (e.g., -qextname) are applied consistently:

-------------- Beginning of Makefile ---------------------

IBM_FC = xlf -lblas
MFL_FC = fc
TIT_FC = f77
SUN_FC = fc

# set FC to be one of the above variables depending on whether you
# are on an RS/6000, Multiflow, Stardent Titan, or Sun
FC = $(IBM_FC)

.SUFFIXES:
.SUFFIXES: .o .F

# change the following to specify wherever the standard Gaussian
# files are kept.
GDIR = /g90

.F.o:
	make -f $(GDIR)/bsd/g90.make $*.o

# This should be a list of the links to be built.
all: l1102.exe

# Each link should have a list of contributing files like this.
# Only routines which have been modified need be listed.
OBJ1102 = ml1102.o 

# Each link to be made needs an explicit rule similar to the
# one below.  If the link is entirely new, the reference to
# the standard version of its library should be omitted.
l1102.exe: $(OBJ1102)
	$(FC) -o l1102.exe $(OBJ1102) $(GDIR)/l1102.a \
	  $(GDIR)/util.a
