I have problems compiling R on HP-UX 10.20
(using native cc and f2c).
The problem arises when building R_X11.sl:
cc -b -o ../../../bin/R_X11.sl dataentry.o devX11.o rotated.o rbitmap.o -lSM -lICE -lX11 -L/usr/local/lib -lm
cc: warning 422: Unknown option "b" ignored.
/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file (dataentry.o) was detected. The linked output may not run on a PA 1.x system.
/usr/ccs/bin/ld: Unsatisfied symbols:
Rf_VectorToPairList (code)
Rf_endcontext (code)
R_NaReal (data)
I have configured by ./configure --with-f2c.
Any hint ?
