Please try this patch https://github.com/syntheticpp/lyx/commit/2470fb442cb2b04a69b2030f28f1da60221556a7?diff=unified Many thanks, with this patch I can compile and with this also the nasty bug http://www.lyx.org/trac/ticket/9892 is fixed. So here is my +1. Please put it in. Could you please also check if http://www.lyx.org/trac/ticket/9892 is fixed for you too with MSVC 2015 Update 2? best regards Uwe

The problem doesn't seem to be the wgetmainargs function because according to MS this had not been changed since MSVC 2010: https://msdn.microsoft.com/en-us//library/ff770599.aspx and with MSVC 2010 everything is fine. I understand the long note at line 102 that LyX as a console-based application is a hack because a genuine GUI-based app would be something else. I am no expert here but wgetmainargs is only used to get data from the console. This seems to be different since a while. One could fix that and I guess peter knows how, Peter?, but why don't we switch and make LyX a GUI application o Windows as described in the long comment. I mean LyX IS already GUI based so what would be the advantage of the console? thanks and regards Uwe
