Dear Tom,
It has worked for me out-of-the box in at least two times, one a while
ago
with R-2.2-something and recently with R-2.4.0. In both cases, I was
running
Debian (with a mix of testing and unstable) on x86. I never had to do
anything, just run the script and at least in one case I did
crosscompile a
package with C++.
R.

Hi everyone,
I am trying to cross-compile a package I wrote using the Yan and Rossini
tutorial "Building Microsoft Windows versions of R and R packages using
Intel Linux". I have got reasonably far with this but when doing the
linking using the line:
i586-mingw32-g++ -shared -s -o mylibrary.dll mylibrary.def mylibrary.o
mylibrary_res.o -L/my/path/RCrossBuild/WinR/R-2.4.0/bin -lR
I get lots of these type of messages:
/my/path/to/mylibrary.cpp:43: undefined reference to
`_GLOBAL_OFFSET_TABLE_'
and other similar linker errors for virtually every object and command
in
the program. After some googling I have found that there may be
problems
with the libgcc.a library and its default -fPIC argument during
compilation.
Has anyone got this tutorial to work and if so how did they overcome
this?
I am attempting to do this on Fedora Core 4 on a 32-bit machine, having
completed all the previous sections of the tutorial for building a
cross-platform version of R.
Many thanks
Tom
