[Help-gsl] undefined reference problem

[Alexander Kubisch]

Hello,

I just tried to compile my C++-program in eclipse with the following 
makefile:

[code]
env_grad.out : main_program.o
   g++ -o env_grad.out main_program.o
main_program.o : main_program.c++ classes.h procedures.h
   g++ -c -lgsl -lgslcblas -lm main_program.c++
clean :
   rm -f *.o
[\code]

The compilation aborts and for every line of program code, in which I 
use gsl-functions, the "undefined reference to" - error occurs. In the 
Includes the gsl-folder is listed and I also tried other 
compiler-commands, like -L/usr/include/gsl and others. Always the same 
problem appeared. Do you have any idea, what could be the reason for 
that? BTW, I'm not a programmer, I'm a biologist, so I'm sorry, if this 
might be a nooby question ;-)

Many thanks,
Alex
