[Help-gsl] URGENT help

[Joy]

Hello there--

Let me confess I'm novice in using GSL. I'm using Cygwin to run a C program
using GSL library. I ran the program gibbs.c and created an object file
using the command

gcc -Wall -I/usr/local/include -c gibbs.c

and the object file gibbs.o was created. For linking I used the command

gcc -L/usr/local/lib gibbs.o -lgsl -lgslcblas -lm

which made  a.exe  file.

Now I want to see the output (probably using .exe file)  and can you please
help me what I need to do ? Also if I want to name .exe file (not a.exe as
default) differently then whaich command do I need to use ?

I look forward to hearing from you ASAP.

Thank you, Joy.
