R devel - May 2006 - R freezes under Windows while loading package

Hi,

we build this R package using C++ code and under linux it works fine.
After installing:
- R version 2.2.1
- minGW gcc version 3.4.2
- perl version 5.8.8
it finally compiled under Windows as well. But, if we try to load the
library, R freezes without stressing the CPU.

Maybe someone had a similar problem and now has a simple solution for
it.


Thanks,
Sebastian Manz,
Timo Breitner.

Presumably the problem is in the DLL.  Can you use dyn.load() to load it 
manually?  If so, you can set a debug breakpoint on each entry point, 
and see where things are going wrong.  Instructions for doing C-level 
debugging under Windows are on my web page,

http://www.stats.uwo.ca/faculty/murdoch/software/debuggingR/

and more general-purpose instructions are in the Writing R Extensions 
manual in 2.3.0.
