In contrast to all other tested operating systems a call of Fortran functions on
Linux x86/64 requires an appended underscore.

The problem occured with package deSolve
(http://r-forge.r-project.org/projects/desolve/)

Relevant code snippets

In R:

> getNativeSymbolInfo("iniaqua", PACKAGE = "deSolve")$address
Error in FUN("iniaqua"[[1L]], ...) :
   no such symbol iniaqua in package deSolve
 > getNativeSymbolInfo("iniaqua_", PACKAGE = "deSolve")$address
<pointer: 0x2b5cd3aa3960>
attr(,"class")
[1] "NativeSymbol"


In Aquaphy.f:

     subroutine iniaqua(odeparms)

      external odeparms
      double precision pars(19)
      common /myparms/pars

       call odeparms(19, pars)

      return
      end
