Hi all,
The call to:
library(rJava)
Results in the following warning massage:
Warning message:
In inDL(x, as.logical(local), as.logical(now), ...) :
DLL attempted to change FPU control word from 8001f to 9001f
After some searching I found the following explanation:
R expects all calls to DLLs (including the initializing call) to leave the
FPU control word unchanged. Many run-time libraries reset the FPU control
word during initialization; this will cause problems in R, and will result
in a warning message like "DLL attempted to change FPU control word from
8001f to 9001f". The value 8001f that gets reported is in the format
expected by the C library routine _controlfp; the raw value that is used
in the FPU register is 037F.
Also with a few old discussions that explain (for a package developer) how
to avoid this.
The question is, should I, as a useR, do anything regarding this warning
massage ?
It's a bug in the rJava package, so you should report it to the
maintainer of that package.
