It is coming, but just like a number of other things, not exactly overnight. It is a release goal. | > | | It actually works ;) I'm using it for testing on my RForge.net machine and yes, it's Debian - everything just works there :). | | But back to the original question. First a minor detail, don't set environment variables use configure variables instead. Second, don't build in the source directory, always create an object directory. Third, r_arch is simply a name you set for the architecture, it has no meaning other than that it's a label. | | So now to the real stuff. If you want 32-bit build, you'll need 32-bit runtime of everything important in your system and the multilib compilers. In Debian (and thus likely in Ubuntu too) that can be achieved by something like | | sudo apt-get install ia32-libs-dev lib32readline6-dev lib32ncurses5-dev lib32icu-dev gcc-multilib gfortran-multilib
Nice one :) I had these installed but was always under the impression that we'd lack things like jpeg, png, ... libs. So it all works as R has 'enough batteries' included? Good to know ... | | Then you can build both 64-bit and 32-bit R, the difference will be in the all compiler flags -- for 64-bit you'll use -m64 (or nothing since it's the default) and for 32-bit you'll use -m32. | | So roughly something like | | tar fxz R-2.13.1.tar.gz | mkdir obj-32 | cd obj-32 | ../R-2.13.1/configure r_arch=i386 CC='gcc -std=gnu99 -m32' CXX='g++ -m32' FC='gfortran -m32' F77='gfortran -m32' | make -j24 && sudo make install rhome=/usr/local/R/2.13 | cd .. | mkdir obj-64 | cd obj-64 | ../R-2.13.1/configure r_arch=amd64 | make -j24 && sudo make install rhome=/usr/local/R/2.13 | | That will leave you with multi-arch R that you can run with | R --arch=i386 # 32-bit | R --arch=amd64 # 64-bit | Packages will be also built as multi-libs. Good luck :) | [BTW the rhome=... setting is entirely optional, I just like to keep my R versions organized…] I shall keep that for the day I'll have to start supporting multiarch in all the r-cran-* packages :) Thanks for waving the cluebat.
