[Help-gsl] about monte

[cnepali]

Hi,

I installed gsl. So, please disregard my previous e-mail "installation 
problem".

I was trying to use monte carlo integration. I just copied a program on this 
given in "GSL Reference Manual" and I compiled using g++. But there was errors 
like:

 /tmp/cc2bFRST.o(.text+0x173): In function `main':
: undefined reference to `gsl_rng_env_setup'

any ideas?
Thanks a lot.
