The problem was not with the pointer but the space between the type and '*' operator. When working with pointers, "find_value_type" of "traits_impl_details" removes the '*' using a substring operation, and when that happened, it tried to find the type of the actual type along with a space. If this is not an intended behaviour of the code, then a possible enhancement could be to strip the type string of the trailing spaces before the find operation.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Ankit Deepak</div></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On Fri, May 19, 2017 at 7:33 PM, Ankit Deepak <span dir="ltr" class=""><<a href="mailto:adadeepak8@gmail.com" target="_blank" class="">adadeepak8@gmail.com</a>></span> wrote:<br class=""><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class="">Hello all,<div class=""><br class=""></div><div class="">I have started working on CastXML recently.
