What changed was that a sufficient number of people asked me to create
an RPM with the shared library and I changed my mind. The aim of the
precompiled binaries is to satisfy most of the people most of the time,
and when I get repeated requests for the same feature, I have to bear
that in mind. People who require optimal performance can still compile
their own.
As for the idea of compiling two distinct binaries packages for R, I am
not especially keen, and not just out of laziness. The problem is that R
packages depend on libR.so, when it exists, so if you uninstall R with a
shared library and then install R without the shared library you get a
broken system.
You can look at the CAPABILITIES file in the same directory as the RPM
to see how it was compiled.

Even the reason I gave in my first email was not up to date (most binary distributions are compiled with this option), my suggest is still valid: why not provide two binaries? Most users can use standard R without sacrificing performance and embedding applications use libR.so and, if needed, a separate binary R_embed.

I certainly welcome this > change and I apologize for my unfounded accusation to R. Why guess? There are accurate statements in the R-admin manual, and the RH RPM change was discussed on this list in 2006: https://stat.ethz.ch/pipermail/r-devel/2006-January/036118.html > BTW, shouldn't --enable-R-shlib be yes by default during ./configure?. No, for the reasons given in the R-admin manual. They include that there are platforms on which --enable-R-shlib cannot be used. We have been working (in R-devel) on changes which are designed to reduce the overhead of the shlib version of R: they do, but it is still over 10% on the platforms checked. (The figures given earlier are optimistic in the sense that they include time spent in compiled code in packages such as stats in a typical R session: worst-case scenarios have up to double that.)

[Rd] Provide both shlib and standard versions of R?
Dear list, To operate R from python via a Python package rpy, R has to be compiled with --enable-R-shlib. This is troublesome since none of the binary distributions (except for windows?) is built with this option so rpy users have to build R from source. This can be quite a challenge, especially on platforms like macOSX. Is it possible to provide both standard and shlib version of R by default? This may not be too hard for R (link twice? I am not quite sure.) but will benefit all applications that embed R. Cheers, Bo __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
