pow__ii
R code works but the shared objects built from fortran code do not find the appropriate libs with functions like __pow_ii or __epx at runtime.
I used to have endless trouble with __pow_ii which as I recall could be be fixed by the correct incantation of the mix of compiler libraries and LD_LIBRARY_PATH. It seemed to be extremely sensitive and never easy to get right. The problem is that pow_ii is not used by R itself, and so when your fortran code does something like 4**2 (or using variables declared as integer) then a call to pow_ii is generated and you need to find the correct library. I eventually fixed the problem by changing the fortran code to 4.0D0**2 (or 4.0D0**2.0D0 ? and declared variables as double). This generates calls to a routine which is used by R itself, and I never had to worry about the libraries again. This also worked better with Splus, which can also be problematic in this regard. I highly recommend this change to anyone distributing fortran code with a package. I'm not sure about __epx.
