<pre wrap="">Hi All,
when building MXE to update to Qt5.9.2 I this time selected the gcc 7 plugin
in MXE to use gcc 7.2.0 instead of 5x. Please don't ask me why - I just
wanted to try ;-)
Now I have this compile error:

Is this s.th. we can even fix in our code (??) or makefiles? Or shall I
better go back to standard gcc 5x again?

<pre wrap="">
this looks like something which isn't a problem on the subsurface side.
my bet is that the mingw 7x "dudes" are doing something wrong with
#include_next.
fixing compiler headers is always a bad idea, so i'd suggest that you
try another compiler and report the issue to MXE.

I looked a little bit around and found this:<br>

<br>
Maybe we can and should fix it in our makefiles because gcc 6 and 7
can be affected?<br>
