MSVC 14 supported about gvsbuild

[pbor]

Hi, we definetely want to support MSVC14, but we are not using it yet so we do not have a way to test right now.

However Fan's upstream projects already support it and also the hexchat script we forked from recently switched to it so it should be fairly easy to do.

Mostly it will be a matter of adding "vs14" folders for each module and copying the files

Hi pbor,
I managed to compile only part of the library. Here is the result of compilation:
...
The following items were successfully built:
ffmpeg
freetype
gettext-runtime
hicolor-icon-theme
libepoxy
libffi
libpng
libxml2
lmdb
openssl
pixman
win-iconv
zlib

The following items failed to build:
fontconfig

The following items were not built because one or more of the other items failed to build:
atk
cairo
cyrus-sasl
enchant
gdk-pixbuf
glib
glib-networking
gsettings-desktop-schemas
gtk
gtk3
harfbuzz
libcroco
librsvg
libsoup
pango
...
It seems that the library 'fontconfig' is not supported for compiling vc14 because of an error (see. fontconfig_error_vc14.txt)

Full report compilation: build_vc14_0.txt

[pbor]

try to change the file

fontconfig/config.h

It has a line

#define snprintf _snprintf

change to something like

#ifndef snprintf
#define snprintf _snprintf
#endif

Note that you will need to remove the "build" and "gtk" dir and restart the build

This method does not work (see. fontconfig_error_vc14_2.txt)

[pbor]

well, the error is now different so it seems to have sorted some kind of effect... can you post the full log for the build failure?

This is a known bug compilation vc14 (fatal error C1189: #error: Macro definition of snprintf conflicts with Standard Library function declaration).

Full report compilation: build_vc14_1.txt

[pbor]

I see... then try to completely remove that line.
Later we can find a proper ifdef

I did not notice the existing directive #define printf _printf in the file 'config.h'. I added a condition to downgrade MSVC:

#if _MSC_VER < 1900
#define snprintf _snprintf
#endif

It seems there is problem solving:
typedef int ssize_t; (#10)

It is necessary to check on the compiler vc12.

Yeah, looking at what the hexchat guys did here hexchat/gtk-win32@2f3c96d I think you need to drop the "_W64" (I am not sure what it is exactly)

This is superseded by #52
