Cross-compilation

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
