I've just installed GSL, and I was reading the introduction and about including the appropriate directory for certain tasks (ie #include<gsl/gsl_sf_bessel.h>) it says
"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."
So I have the location, but how do I do this?
If it told me, I didn't understand... Help appreciated.
It depends on your compiler. For example, if you are using gcc 4.2 the relevant documentation to read would be Options for Directory Search.

Hello,
Please tell how you installed GSL. Did you down the load source code and complete the standard, ./configure, make, sudo make install? Or did you use a package manager?
Chances are that compiling with this will work (this assumes that GSL is install in /usr/lib or /usr/local/lib for a unix/linux type system).
gcc -Wall main.c -lgsl -lcblas
(where main.c is the name(s) of the file(s) that are to be complied.)
