[Bioc-devel] genefilter package update?

Hi Paul

Thanks for the update. R itself does not have C++ code, but does try
to configure itself correctly for C++ code in packages. Apparently
this is not the case for your system.

I think the short-term solution is to configure and make R with the
appropriate flags set at configuration time. I _think_ the appropriate
flag is SHLIB_CXXLDFLAGS=-lCrun. This is from reading section C.4 of
the R Installation and Administration Manual, available from your
favorite cran (mine is http://cran.fhcrc.org) under the 'Manuals'
link. Setting the flag at configuration should then record it in the
installation R_HOME/etc/Makeconf. This file is consulted when packages
are installed.

The place to ask for more help or to suggest more permanent solutions
is on the R-devel mailing list (accessible from the R home
page). Likely you will get help, but from reading the installation
manual it seems a bit like modifications to configuration scripts will
not necessarily be incorporated -- perhaps to do so implies more
experience and long-term support for this particular compiler /
platform combination than members of the R development team are able
to commit to.

Hope that helps
