Hi,
I used .C to call the C functions inside R. Everything works fine on the
linux sever.
I installed cygwin on my windows xp x64 platform and used rcmd shlib xxx.c
to compile. Everything works fine till now and xxx.dll is generated. But
when I use dyn.load("xxx.dll") in R, it will open another R window and
the
original R window becomes "Not responding", nothing loaded in both R
window.
Anyone has similar experiences before. Thanks a lot.
BTW: I tried some other .dll files from the existed library. everything
works ok. so I think maybe something wrong with my C code. But why it works
fine on the linux server? Any guess or suggestion for this?

Thanks a lot.It has been the case that you are recommended not to build shared library objects under Cygwin, but rather to follow the instructions in: http://www.murdoch-sutherland.com/Rtools/ carefully - that is build under Windows using the chosen tools. The other .dll files you report functioning correctly were built in this way, so the easiest thing to do is to build in the same way.> > BTW: I tried some other .dll files from the existed library. everything > works ok. so I think maybe something wrong with my C code.
