[Help-gsl] compiling under fedora core 5

[Fred J.]

Dear users, 
I installed the gsl files under linux fedora core 5, after reading the docs it 
does not appear to me how to compile and link the following program which thus 
gives the afterwards errors, 

thanks for you help

here is the make file 
#LDFLAGS = -lposix
CXXFLAGS = -gdwarf-2
OBJS := $(patsubst %.cpp,%.o,$(wildcard *.cpp))
COMP = g++

proj: $(OBJS)
    $(COMP) -Wall -gdwarf-2 -o proj $(OBJS) #$(LDFLAGS)
 
#-Wall turns on all warnings
#-gdwarf-2 for dubugging note gdb manual 12.4.1
clean: 
    rm -rf *.o proj
