Jul 11, 2019 Getting started with GSL - GNU Scientific Library on Windows, macOS and Linux; Install Code::Blocks and GCC 9 on Windows - Build C, C and Fortran programs; C Implementing a Chaos Game simulator; Install GCC 9 on Windows - Build C, C and Fortran programs; C20 span tutorial; A Happy Halloween from C and an IIFE lambda. Feb 27, 2015 This video includes four parts, download, install, coding and compile. The GSL library is not installed in the default directory (/usr/local). Instead, we can put it in any path we want. Step 0: Checking existence of GSL (and Fink) I use Fink to install the GNU Scientific Library (GSL).Fink is like Aptitute (high-level package manager) in Linux. If you are not sure if GSL is already installed, at the Terminal prompt $ type.
Install XCode command-line tools
If you already have XCode command-line tools installed, then typing clang++ at the terminal should produce output like the following:
If they aren't installed, then the clang++ command should automagically initiate the installation for you.
Install Qt
The latest version of Qt as of this writing -- Qt 5.12.1 -- should work fine. Obtain it from https://qt.io/. Once you have downloaded the dmg, simply open it and double-click the install app it contains.
Once the installation is complete, you will probably need to add the Qt bin directory containing qmake to your PATH. Using Qt's default installation location that path on Larry's system is:
/Users/larryy/Qt5.12.1/5.12.1/clang_64/bin
Then open a terminal and verify that typing qmake --version produces output like the following:
Install GSL
Install the GNU Scientific Library, which can be found at http://www.gnu.org/software/gsl.
You may try the following sequence of commands in your terminal, which is the procedure Sean uses to download, build, and install:
The OSX-specific install is now complete, so proceed to the POSIX installation procedure.
1. Introduction
GNU Scientific Library(GSL) is a numerical library for C and C++ programmers. It’s a free software under the GNU General Public License.This library provides over 1000 functions which almost covers all the regular mathematical routines.
The complete range of subject areas covered by the library includes:
Complex Numbers， Roots of PolynomialsSpecial Functions， Vectors and MatricesPermutation， SortingBLAS Support，Linear AlgebraEigensystems， Fast Fourier TransformsQuadrature， Random NumbersQuasi-Random Sequences， Random DistributionsStatistics， HistogramsN-Tuples， Monte Carlo IntegrationSimulated Annealing， Differential EquationsInterpolation， Numerical DifferentiationChebyshev Approximation， Series AccelerationDiscrete Hankel Transforms， Root-FindingMinimization， Least-Squares FittingPhysical Constants， IEEE Floating-PointDiscrete Wavelet Transforms， Basis splines
- The library uses an object-oriented design. Different algorithms can be plugged-in easily or changed at run-time without recompiling the program
- Unlike the license of proprietary numerical libraries the license of GSL does not restrict scientific cooperation, instead, it allows you to share your program freely with others.
- The interface was designed to be simple to link to very high-level language, such as GNU Guile or python.
Primarily Supported Platforms:
Developed on the following platform:
- GNU/Linux with gcc
Other platforms:
- SunOS 4.1.3 & Solaris 2.x(Sparc)
- Alpha GNU/Linux, gcc

2. Installation
The current version is GSL-1.16. It was released on 19 July 2013. This version can be found in the gel subdirectory on your nearest GNU mirror )
Recommended way to install:
use a package manager
- Homebrew(for mac users):
brew install gsl - Synaptic(for Linux users): preinstalled in Ubuntu, Debian administers need to
apt-get install synapticin terminal - Cygwin(for windows users):

3. Examples
The error code numbers returned by library functions are defined in the file gsl_errno.h. They all have the prefix GSL_ and expand to non-zero constant integer values.
Gnu Scientific Library Visual Studio
- Macro: int GSL_EDOMDomain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined (like EDOM in the C library)
- Macro: int GSL_ERANGERange error; used by mathematical functions when the result value is not representable because of overflow or underflow (like ERANGE in the C library)
- Macro: int GSL_ENOMEMNo memory available. The system cannot allocate more virtual memory because its capacity is full (like ENOMEM in the C library). This error is reported when a GSL routine encounters problems when trying to allocate memory with malloc.
- Macro: int GSL_EINVALInvalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function (like EINVAL in the C library).
int status = gsl_function (...) // status 0, no error
printf ('error: %sn', gsl_strerror (status)); //gsl_strerror converts the error codes into a message.
