[Help-gsl] ERROR "undefined reference"

[Lee Seongjoo]

Hello,

I am new to this library. I have installed GSL on Ubuntu 10.04 using
package manager. After installed the library, I was trying the
tutorial. Then, I got this error "undefined reference to
'gsl_sf_gessel_J0'. When building the program, it did not complain
about locating the header file. And all the library files are in the
default place. But still I got this build error.
