Works for me and many others too.... | | Thanks, Dirk, for the makefile debugging tip. It seems this line: | R_HOME := $(shell R RHOME) | | goes horribly wrong if R reports a warning. It was outputting: | WARNING: ignoring environment value of R_HOME | /usr/lib64/R | | I cannot find any commandline parameters that will shut it up. :-( I see. Classic local fsck up though :) | One idea for a Makefile fix is: only setting R_HOME if no environment | variable already set. Patches welcome. I think there is even an idiom for that but I always get lost whether that was shell or makefile syntax. | Is there a use case where someone has set R_HOME | in their environment, but does not want to use it, and instead wants to | use what "R RHOME" outputs? Yes. Many R (Core) developers have several R installations and use $PATH or other variables to point to it. This can reflect it. If you need something different you can always hardcode it. It /just/ an example Makefile and I do not plan to replace or augment it with a full-blown configure script. | Darren | | P.S. Going back to my machine it appears that R_HOME is set to | /usr/lib/R; when I explicitly set it to /usr/lib64/R the warning goes away. | /usr/lib64 is a symlink to /usr/lib, so the warning is just noise. It | has not affected compiling any R packages, or using Rcpp, inline, etc. | | The problem setting was found in /etc/environment, and may have been | leftover from an earlier R installation. Also, it seems the "R RHOME" | command is hyper-sensitive: If I set R_HOME to "/usr/lib64/R/" it still | complains. I need to remove the trailing slash to appease it. Still "merely" your issue and nothing that generalizes. I happen to be the Debian maintainer for R, and hence also indirectly behind what may be a few ten thousand (or more?) Ubuntu R installations which "just work" if you use them as packaged, either by the distro or via the more current backports from CRAN. If someone breaks their local R installation by various enhancements, they get to keep the pieces. And you can always apply to get your money back. Transfers of zero dollars are near-instantaneous.
