Not that I know of... Back in the old days we had config.cache playing tricks on people, but it shouldn't be there anymore. If you're not already doing so, do yourself a favour and build in a separate directory, keeping the sources untouched. It's much easier to clean up and start over that way. > >>Hi, > >> I built R with Portland Group compiler, but I noticed one thing > >> that when I ran configure for the first time on AMD machine, I got > >> the following error: > >> > >> > >> checking whether the C compiler works... configure: error: cannot > >> run C compiled programs. > >>If you meant to cross compile, use `--host'. > >>See `config.log' for more details. > >> > >> > >> > >> so I tried to set host=x86_64-unknown-linux-gnu, which seems to > >> work, except what puzzles me is that there is warning messages > >> indicating C longs are 4 bytes. > >> > >>******************************************* > >>% configure --host=x86_64-unknown-linux-gnu > >>. > >>. > >>. > >>R is now configured for x86_64-unknown-linux-gnu > >> > >> Source directory: . > >> Installation directory: /usr/local/R.pgcc > >> > >> C compiler: /usr/pgi/linux86-64/6.0/bin/pgcc -g > >> -O2 -mieee-fp > >> C++ compiler: /usr/pgi/linux86-64/6.0/bin/pgCC -g > >> Fortran compiler: /usr/pgi/linux86-64/6.0/bin/pgf77 -O2 > >> > >> Interfaces supported: X11 > >> External libraries: readline > >> Additional capabilities: PNG, JPEG, MBCS, NLS > >> Options enabled: R profiling > >> > >> Recommended packages: yes > >> > >>configure: WARNING: assuming C ints are 4 byte on x86_64-unknown-linux-gnu > >>configure: WARNING: assuming C longs are 4 byte on x86_64-unknown-linux-gnu > >>configure: WARNING: you cannot build info or html versions of the R manuals > >> > >> > >>Am I defining a wrong host? > >> > > > >You're not doing yourself a favour, anyway. 4-byte longs are > >definitely not a good idea on Linux.
