Hi,

I trying to compile R-1.6.2 on Red Hat Linux 8.0 running on the Itanium2(IA64)
platform and encountered the following message:

make[1]: Entering directory `/home/nganm/R-1.6.2/src/modules/lapack'

make[1]: *** [lapack.so] Error 1
make[1]: Leaving directory `/home/nganm/R-1.6.2/src/modules/lapack'
make: *** [R] Error 2

I have traced the problem to be: lapack.o is not compiled with the -fPIC flag,
but ld is trying to link it with code that is compiled with -fPIC. So, I need to
get gcc to compile lapack.c with the -fPIC. I don't know where to change the
Makefile or Makeconf. Please help.

thanks,
Mike
