Currently there is no way to specify R_HOME at build time - it is hard-coded to ${prefix}/lib/R. This is slightly inconvenient for special setups (e.g. installing different versions of R in parallel). I was thinking of something like: ./configure --prefix=/usr --enable-custom-R-home=/usr/share/R-2.0 which will use /usr/share/R-2.0 as R_HOME - otherwise it would use /usr/lib/R The following patch (against R-devel) implements that functionality, allowing more flexible builds/installs. As a side-effect it finally prints R_HOME in the configure summary. Please let me know what you think ... (and yes, I know you don't have to run make install so one could build it in target place, but I think the above is more clean ..). Cheers, Simon -------------- next part --------------
