=== C++ support ===
The GSL can be used in [[C++]] classes, but not using pointers to member functions, because the type of ''pointer to member function'' is different from ''pointer to function''.<ref>[http://www.parashift.com/c++-faq-lite/pointers-to-members.html#faq-33.1 Pointers to member functions]. {{webarchive|url=https://web.archive.org/web/20041013202445/http://www.parashift.com/c++-faq-lite/pointers-to-members.html |date=2004-10-13 }}.</ref> Instead, pointers to static functions have to be used. Another common workaround is using a [[Function object|functor]].

C++ wrappers for GSL are available.<ref name="ccgsl"/><ref name="gslmm"/><ref name="gslwrap"/><ref name="gslcpp"/> Not all of these are regularly maintained. They do offer access to matrix and vector classes without having to use GSL's interface to [[malloc]] and [[Free (programming)|free]] functions. Some also offer support for also creating workspaces that behave like [[Smart pointer]] classes. Finally, there is (limited, as of April 2020) support for allowing the user to create classes to represent a parameterised function as a [[Function object|functor]].

While not strictly wrappers, there are some C++ classes <ref name="osscl">[https://neutronstars.utk.edu/code/o2scl/html/index.html o2scl Object-oriented Scientific Computing Library]; </ref><ref name="yat">[https://web.archive.org/web/20101103060841/http://dev.thep.lu.se/yat/ yat].</ref> that allow C++ users to use the Gnu Scientific Library with wrapper features.
