I don&#x27;t own any ios device and support for it isn&#x27;t merged in the repository yet. There are a few git repositories (a bit dated though), regarding building ECL with iPhone[1], and there is a project by Kris Kohlhepp[2] – I&#x27;ve wrote to him recently with the question about patches. If anyone has iOS and will submit a proper PR with some notes about building I&#x27;ll gladly accept it :-)<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;search?utf8=%E2%9C%93&amp;q=ecl+iphone&amp;type=Repositories&amp;ref=searchresults" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;search?utf8=%E2%9C%93&amp;q=ecl+iphone&amp;type=R...</a><p>[2] <a href="https:&#x2F;&#x2F;chriskohlhepp.wordpress.com&#x2F;embeddable-common-lisp-on-iphone&#x2F;" rel="nofollow">https:&#x2F;&#x2F;chriskohlhepp.wordpress.com&#x2F;embeddable-common-lisp-o...</a><p>BTW, ECL has also (untested, but integrated) ports for NaCL and pNaCL, which should run cross-platform.
