Help linking f77 libraries into gfortran



I've recently installed gcc 4.2.1 on i686-pc-cygwin from source code. I've
been testing the gfortran compiler and ran across a problem linking f77
libraries. My Makefile is:



mingwlib = -L/cygdrive/c/Devel/MinGW/lib

CFLAGS = -O2 -malign-double -mtune=pentium4

CC = gfortran

librs = -lSLATEC \

-lPSPLOT

objects = TA1Main.o \

random.o \

TA1QPoutput.o \

TA1SelectPort.o \

TA1Neighbor.o \

TA1Calcqr.o \

TA1Threshold.o \

TA1Solver.o \

TA1PSplot.o

TA1 : $(objects)

$(CC) $(CFLAGS) $(objects) $(mingwlib) $(librs) -o TA1.exe

TA1Main.o : TA1Main.f

$(CC) $(CFLAGS) TA1Main.f -c

random.o : random.f

$(CC) $(CFLAGS) random.f -c

TA1QPoutput.o : TA1QPoutput.f

$(CC) $(CFLAGS) TA1QPoutput.f -c

TA1SelectPort.o : TA1SelectPort.f

$(CC) $(CFLAGS) TA1SelectPort.f -c

TA1Neighbor.o : TA1Neighbor.f

$(CC) $(CFLAGS) TA1Neighbor.f -c

TA1Calcqr.o : TA1Calcqr.f

$(CC) $(CFLAGS) TA1Calcqr.f -c

TA1Threshold.o : TA1Threshold.f

$(CC) $(CFLAGS) TA1Threshold.f -c

TA1Solver.o : TA1Solver.f

$(CC) $(CFLAGS) TA1Solver.f -c

TA1PSplot.o : TA1PSplot.f

$(CC) $(CFLAGS) TA1PSplot.f -c

..PHONY : clean

clean:

rm -rf $(objects) TA1.exe



This produces many errors similar to:

/cygdrive/c/Devel/MinGW/lib/libSLATEC.a(xersve.o):xersve.f:(.text+0x206):
undefined reference to `_s_copy'

The program compiles using g77 without problems. I'd like to know if it is
possible to use the SLATEC and PSPLOT as-is or do I need to recompile new
libraries to use in gfortran. (For the moment, I'd like to link to these
existing libraries if possible.) I've tried various gfortran switches and
macros but to no avail.

Thanks Mike
