This repository contains a copy of the latest stable version of GSL, with two main additions:

• a cmake build system
• optional inclusion of the AMPL GSL bindings, to access GSL functions from AMPL; documentation for the AMPL bindings can be found at https://amplgsl.readthedocs.io/en/latest/

To build the AMPL bindings:

1. Make sure that the ASL submodule is initialized (in /ampl/thirdparty/asl).

2. Create a build directory and move there:

   mkdir build
   cd build
   

3. Initialize the build files with your desired generator, for example:

   cmake .. -G"Unix Makefiles"
   

4. Build the resulting build files accordingly, for example:

   make .
   

If building GSL without the AMPL bindings:

1. Create a build directory and move there:

   mkdir build
   cd build
   

2. Initialize the build files with your desired generator, defining the variable ```NO_AMPL_BINDINGS````

   cmake .. -G"Unix Makefiles" -DNO_AMPL_BINDINGS=1
   

3. Build the resulting build files accordingly, for example:

   make .
   

1. Defining GSL_DISABLE_TESTS skips the test generation, for example:

   cmake .. -DGSL_DISABLE_TESTS=1
   

2. There is experimental support to build only a subset of the GSL library; note that this is only supported when not building the AMPL bindings. To generate only some libraries of the GSL, define BUILDLIBS when calling cmake as a comma separated list of GSL directories. An example follows:

   cmake .. -DBUILDLIBS=ode-initval2,linalg -DNO_AMPL_BINDINGS=1
   

   All the dependencies are handled automatically; please note that the tests often have additional dependencies therefore, to fully benefit from this facility, disable them. For example:

   cmake .. -DBUILDLIBS=ode-initval2,linalg -DNO_AMPL_BINDINGS=1 -DGSL_DISABLE_TESTS=1
   

3. Turn off building of documentation via:

   cmake .. -DDOCUMENTATION=OFF
   

The current stable version of GSL is always available from ftp.gnu.org in the directory /pub/gnu/gsl.

A list of mirror sites can be found at http://www.gnu.org/order/ftp.html

GSL follows the standard GNU installation procedure. Please consult the INSTALL file in this distribution for more detailed instructions.

For information about specific platforms and compilers see the "Compilation Notes" section in the INSTALL file.

The project homepage is http://www.gnu.org/software/gsl/

See the NEWS file for recent changes to the library.

The GSL Manual has been published and can be ordered from most bookstores. The publication details are,

GNU Scientific Library Reference Manual - Revised Second Edition, M. Galassi et al, ISBN 0954161734 (620 pages, paperback).

The money raised from sales of the manual helps support the development of GSL.

A Japanese translation of the reference manual is available from the GSL website above (thanks to Daisuke TOMINAGA).

A list of known bugs can be found in the BUGS file. Details of compilation problems can be found in the INSTALL file.

If you find a bug which is not listed in these files please report it to [email protected].

All bug reports should include:

   The version number of GSL, and where you obtained it.
   The hardware and operating system
   The compiler used, including version number and compilation options
   A description of the bug behaviour
   A short program which reproducibly exercises the bug

It is useful if you can check whether the same problem occurs when the library is compiled without optimization. Thank you.

Any errors or omissions in the manual can also be reported to the same address.
