> He needs to be made aware that it's unbuildable with MSVC. Is it really? Actually Visual Studio 2015 was only compiler I tested the code against, but maybe older ones are broken. Anyway, the backend shouldn't be used on any production code (specially as it's performance issues) even the fact it currently partially supports an Arabic typographical feature not offered by harfbuzz—which currently has not any suitable way to be accessed from the API so nvm about it. <div class="gmail_quote"><div dir="ltr">On Mon, Jun 13, 2016, 5:55 PM John Emmas <<a href="mailto:johne53@tiscali.co.uk">johne53@tiscali.co.uk</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 13/06/2016 13:51, Khaled Hosny wrote: > DirectWrite and Uniscribe backends should be disabled > by default since they are only for testing purposes > > [...] > > Or may be the issue is that you are using your own build system and just > included all the source files > Hi Khaled, You're right to an extent. I did include 'hb-directwrite.cc' in my VC sources but it was mostly because of something I read in README.txt:- DIRECTWRITE: Enable (experimental) DirectWrite platform shaper support, requires a rather recent Windows SDK, and at least Windows Vista It looks like I misunderstood that because I took it to mean that 'hb-directwrite.cc' should be buildable with the more recent Windows compilers. Thanks for the clarification.
