Dear Vennetha I am running R on a mac too.
Please see if my comments below helps. > On Jun 16, 2016, at 5:00 PM, Kodalore Vijayan, Vineetha W <vwk...@mun.ca> > wrote: > > I'm trying to write an R package that calls a Fortran subroutine on my Mac > os x El Capitan with Xcode 7 and gfortran 6.1, R 3.3.0. > > I couldn't build the library with my current namespace commands. > I get the following error: > > > * installing *source* package ‘Nepidemic’ ... > ** libs > gfortran -fPIC -Wall -g -O2 -c randomepi.f95 -o randomepi.o > gfortran -dynamiclib -Wl,-headerpad_max_install_names -undefined > dynamic_lookup -single_module -multiply_defined suppress > -L/Library/Frameworks/R.framework/Resources/lib -L/usr/local/lib -o > Nepidemic.so randomepi.o -F/Library/Frameworks/R.framework/.. -framework R > -Wl,-framework -Wl,CoreFoundation The name of the library created by r cmd shlib is Nepidemic.so. > installing to > /Users/Vineetha/myrlibrary/myrpackages/Nepidemic.Rcheck/Nepidemic/libs > ** R > ** preparing package for lazy loading > ** help > *** installing help indices > ** building package indices > ** testing if installed package can be loaded > Error in library.dynam(lib, package, package.lib) : > shared object ‘randomepi.so’ not found Note that the r cmd check is looking for randomepi.so so it means that it is calling the wrong library (it should be Nepidemic.so).
