[R] 32bit R303 calls external C functions

[Li, Yan]

Dear All,

I build a R package which will need to call external C functions. I registered the C functions in the NAMESPACE file and include 32bit and 64bit dlls in the packages. If I load the package in 64bit R and calls the external C functions, it works fine. However if I load the package in 32bit R and call the external C functions, it either does not work properly or gives back error message saying cannot find the external C functions.

When I built the same package in R2.15.1, there is no such issue.

I checked the update news for R303 and found most .C is replaced by .Call. I modified the code but the package cannot be loaded and R ended abnormally.

Does anyone know if there any difference of 32bit R303 calling external C from 64bitR303? Thank you!

Regards,
Yan
