Using GSL 1.16 on CentOS 6.5

1. Uninstalling lower versions of GSL

    Check whether a lower version of GSL is installed as follows,

Figure 1. Checking installed version

  and, if it does, uninstall it.

Figure 2. Uninstalling GSL of lower versions

2. Downloading GSL 1.16 source files

    Download archive file gsl-1.16.tar.gz from GNU's GSL directory.

3. Extracting source files

    Open a terminal and change directory to where the downloaded file exists. As root, extract files as follows.

Figure 3. Extracting source files

4. Compiling and installing

    Compile GSL 1.16 sources and install as follows.

5. Registering GSL shared libraries for dynamic linking  

  

    As we specified as one of configure options, '--prefix=/usr/local/gsl-1.16'  (see Figure 2), installed GSL libraries reside in /usr/local/gsl-1.16/lib, which is not included in ld's lookup path. Force ld to include the path by adding a file in '/etc/ld.so.conf.d' as follows.

  

Figure 5. Registering shared libraries - 1

  

  Insert a line into the file.

  

Figure 6. Registering shared libraries - 2

  

  Call 'ldconfig', and check if GSL libraries are loaded.

6. Using GSL

  

    When developing, if you want to compile a source which utilizing GSL libraries, you need to specify the paths of GSL headers and libraries as compile options. For example, see Figure 8.
