I doubt that any of the above commands produce the error message you
show. Most probably you have are running a command like "gcc
example.c" (notice the .c instead of .o?)

When reporting error, please copy&paste the complete relevant block
from your terminal/IDE/whatever!


The solution to your problem is also described in section 2 of the
manual:

,----[ (info "(gsl-ref)Compiling and Linking") ]
| If the directory is not installed on the standard search path of your
| compiler you will also need to provide its location to the preprocessor
| as a command line flag.  The default location of the `gsl' directory is
| `/usr/local/include/gsl'.  A typical compilation command for a source
| file `example.c' with the GNU C compiler `gcc' is,
| 
|      $ gcc -Wall -I/usr/local/include -c example.c
