fortran Makefile

[Paul Gilbert]

My library uses compiled code which I converted from fortran to C with f2c. I
put copies of the same Makefile in the both dse/src and dse/src-c. (I'm not sure
why, but I niavely assumed the same Makefile might work.) Now, I haven't tried
the fortran version with R. But of course the first person (as far as I know) to
actually try and use the package defaulted to compiling the fortran directly
(using R INSTALL). I assume this is something that gets set by configure, but
I'm not sure. What should be in the Makefile for the fortran, or should I not
have any Makefile in the src directory? The src-c/Makefile is

LIBNAME=dse
LD=ld
OBJS= dsefor.o
all: $(LIBNAME).so message
$(LIBNAME).so: $(OBJS)
      $(LD) $(SHLIBLDFLAGS) -o $@ $(OBJS)
clean:
      @rm -f *.o *.so

Below is a copy of an email with the errors from the attempted fortran compile,
and a manual way to compile, but I'm not sure how much of that should be done in
the Makefile and how much is done by configure.

Thanks a lot for providing dse for R. I installed it under Linux. The 'usual'
installation fails as your Rdse/dse/src/Makefile uses implicit rules quite a
bit. It calls g77 first as the compiler. However, each of g77 5.0.19, 5.0.20
and 5.0.21 failed on dsefor.f, mostly with errors of the following type:

dsefor.f:283:
         SUBROUTINE KFP(EY, HPERR, PREDERR, ERRWT,
                    1
dsefor.f:1695: (continued):
                     CALL KFP(F2, HPERR,PREDERR, ERRWT,
                          2
Argument #18 (named `r') of `kfp' is one type at (2) but is some other type at
(1) [info -f
g77 M GLOBALS]
However, it works fine with a manual
        fort77 -c -O2 -fPIC dsefor.f
        gcc -shared -o dse.so dsefor.o
