            the C and fortran files and generates the shared library.

            On the internal technical level, under GNU/Linux and Mac OS X, the ilib_* function are based on the autotools. First, a configure is executed to detect compilers available. Then, a make is launched with the provided arguments.

        </para>
        <para>
            Since version 6.0.1, under GNU/Linux, Scilab detects where the libstdc++ is located (thanks to the command <emphasis role="italic">gcc -print-search-dirs|awk -F= '$1=="libraries: "{print $2}'</emphasis>). Previously, the dynamic link was using the libstdc++ embedded in Scilab.
