Dear R-list,
I want to use shared library of gsl in R(2.15.1) on unix .I have a makefile such as 
CC = gcc
PKG_LIBS -lgsl -lgslcblas -lm -lpthread
OBJS_SPB = calc_spb.o k.o dk.o ddk.o
calc_spb.so : $(OBJS_SPB)
      $(CC) -shared -o calc_spb.so $(LIBS) $(OBJS_SPB)
clean :
      rm -f ../*.o *.o
      rm -f *.so
I use R CMD SHLIB calc_spb.c in terminal window of unix and in my directory was built  calc_spb.o and calc_spb.so.
And  I use dyn.load in R the error is
Error in dyn.load(“calc_spb.so”):
Unable to load shared object ‘/home/mir/cal/calc_spb.so’:
/home/mir/cal/calc_spb.so: undefined symbol :gsl_finite
Thanks to all who tried to help me in solving my problem.
