When building the X11 modules under HPUX 11.23 I get the following errors ld: Unsatisfied symbol "Rf_isNull" in file dataentry.lo ld: Unsatisfied symbol "Rf_length" in file dataentry.lo ld: Unsatisfied symbol "Rf_warningcall" in file devX11.lo ld: Unsatisfied symbol "UNIMPLEMENTED" in file dataentry.lo ld: Unsatisfied symbol "R_alloc" in file devX11.lo ld: Unsatisfied symbol "R_GlobalEnv" in file dataentry.lo ld: Unsatisfied symbol "R_setX11Routines" in file devX11.lo ld: Unsatisfied symbol "Rf_devNumber" in file devX11.lo ld: Unsatisfied symbol "Rf_elt" in file devX11.lo ld: Unsatisfied symbol "R_NaInt" in file dataentry.lo I assume I need to link in an R library built earlier; which library would I need? Please reply directly, as I am not on the list. Thanks Chuck Fisher chuck at uky.edu
