Hello,
After much tinkering I managed to build packages using the 64bit version of
R with the help of hints from
http://www.murdoch-sutherland.com/Rtools/
and
http://www.stats.ox.ac.uk/~ripley/Win64/W64porting.html
and
R-admin Manual.
But a hack was required, and this seems to be related to
a comment about underscores at the end of the second
reference above (but this comment is about FUTURE
changes in R starting with 2.12.x, and I'm not sure how
it applies to the current problem using 2.11.1).
If I simply follow the instructions of the first reference I
get lots of "cannot export / symbol not defined" errors because
by default the leading underscore is stripped off during the
shared library build process, specifically, all names in
tmp.def (created in share/winshlib.mk) do not contain a
leading underscore.
If I modify share/winshlib.mk so that the leading underscore
is not stripped everything works fine.
Have I missed some documentation explaining what is
going on here?
Thanks,
Dominick
