R help - Jun 1999 - R-0.64.1 make problem: Solaris 2.4

Greetings,

I'm attempting to install R-0.64.1 on a Sun Sparc 20 running Solaris 2.4
with
gcc-2.7.2.2, g77-0.5.20 and Gnu make 3.76-1.

On several occasions, the make process aborted when trying to build the shared
object
file for the modreg package (its first attempt at such a beast).  In all
attempts, the error
message is as follows:

../../../../bin/R SHLIB -o modreg.so bsplvd.o bvalue.o bvalus.o ksmooth.o
loessc.o
loessf.o ppr.o qsbart.o sbart.o sgram.o sinerp.o sslvrg.o stxwx.o
make: Fatal error: Unknown option `-w'
gmake[4]: *** [modreg.so] Error 1
gmake[4]: Leaving directory `/tmp/R-0.64.1/src/library/modreg/src'

In addition, I got the following error messages in this directory on the latest
attempt:

g77 -O2 -PIC -c loessf.f -o loessf.o
gcc: unrecognized option `-PIC'
g77 -O2 -PIC -c ppr.f -o ppr.o
gcc: unrecognized option `-PIC'
...

In config.site, I specifically requested the option FPICFLAGS=-fPIC, consistent
with
CPICFLAGS.  I also set SHLIBLDFLAGS=-G in config.site. Furthermore, no errors
or warnings about setting these flags in ./configure were encountered, since it
(finally) found xmkmf.
>From the man page,  -w is a legitimate option for Gnu make (gmake on this
system),
so I'm at a loss how to proceed at this point.  I don't understand why
g77 is using the
option -PIC  when it was set to -fPIC in config.site.

It seems clear that the problem is not with the modreg code, but rather
something with
the make process on this platform. Suggestions gratefully accepted...

Thanks in advance,
Dennis

This is calling make not gmake, so you have not told the configure
process you will be using gmake. Try (under csh)

env MAKE=gmake ./configure

Alternatively, add

MAKE=gmake

to config.site.

Final alternative: use Sun's make.

It looks to me as if the configure script will override those settings, as
it has


CPICFLAGS=${CPICFLAGS-${cpicflags}}
FPICFLAGS=${FPICFLAGS-${CPICFLAGS}}
SHLIBLDFLAGS=${SHLIBLDFLAGS-${shlibldflags}}
...
  *solaris*)
    SHLIBLDFLAGS="-G"
    if ${cc_is_gcc}; then
      CPICFLAGS=-fPIC
    else
      CPICFLAGS=-KPIC
    fi
    if ${f77_is_g77}; then
      FPICFLAGS=-fPIC
    else
      FPICFLAGS=-PIC
    fi

It seems likely that it is failing to detect that your g77 (which is
rather old) is actually g77. 

The solution is to run

rm config.cache
env MAKE=gmake ./configure
edit Makeconf to set FPICFLAGS
gmake
