Dear all, I'd like to share my experiences in building R 1.8.0 on an Alpha/Tru64 UNIX 5.1 machine. I used the following modifications in file config.site: CC=cc F77=f77 CXX=c++ MAKE=gmake with these settings I was able to successfully run ./configure MAKE=gmake I had to manually unpack the files in src/library/recommended to get gmake running through the end (otherwise gmake complained about a missing method for survival). Everything worked fine then. gmake check produces three errors in arith.R . All of these errors are due to an occurrence of a -0 instead of 0. Unfortunately gmake check stops here, with gmake check FORCE=FORCE yielding the same result. gmake install runs without problems.
