Dear R-list,
I want to use shared library of gsl in R(2.15.1) on unix .I have a makefile
such as
Well, don't try to use a Makefile as you do not know what you are doing.
Use Makevars instead.
CC = gcc
CFLAGS = -fPIC -O2
PKG_LIBS -lgsl -lgslcblas -lm -lpthread
That is missing a =
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)
You 'defined' PKG_LIBS not LIBS and your terms are in the wrong order.
Whether the latter matters depends on which 'unix' this is.
On most 'unix' systems a Makevars with
PKG_LIBS = -lgsl -lgslcblas -lm
would suffice. Or even
PKG_LIBS = `gsl-config --libs`
clean :
rm -f ../*.o *.o
clean.so:
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
Dyn.load(“calc_spb.so”)
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.
