Building avxsynth

https://github.com/avxsynth/avxsynth/wiki

Note: Optional

WINDOWS under MinGW

Launch MinGW the usual way as if you are going to build FFMPEG.

You are gonna need log4cpp: http://log4cpp.sourceforge.net/

log4cpp needs pkg-config:

You need to pull down the pkg-config utility and build it yourself.  Once built you need to "autoreconf -i" in the avxsynth src dir.  Then you will have a good configure.

More here: https://askubuntu.com/questions/468661/how-to-fix-pkg-prog-pkg-config-command-not-found-error

Use git to get the pkg-config src: https://cgit.freedesktop.org/pkg-config

You are gonna need libcairo: https://cairographics.org/download/

git clone git://anongit.freedesktop.org/git/cairo

./configure --enable-png=no --enable-svg=no

Have to edit cairo-missing.h and comment out typedef SSIZE_T ssize_t;

libcairo needs libpng: http://www.libpng.org/pub/png/libpng.html

libpng's configure works, but the build broke.  Had to fix up a header file.

libcairo needs pixman: git clone git://anongit.freedesktop.org/git/pixman.git

You are gonna need libpango 1.4.2: http://ftp.gnome.org/pub/GNOME/sources/pango/

Which needs glib 2.54.3: https://download.gnome.org/sources/glib/2.54/

./autogen.sh

./configure --with-pcre=internal --enable-static --disable-shared

Remove DllMain() from gtype.c

Edit gio/gwin32appinfo.c, at line 37 add: #include <wctype.h>

Edit gio/gwin32appinfo.c, at line 519 add:

#ifndef LOAD_LIBRARY_AS_IMAGE_RESOURCE
#define LOAD_LIBRARY_AS_IMAGE_RESOURCE 0x00000020
#endif

Edit gio/gwin32networking.h, replace lines 27-29 with this:

typedef INT (WSAAPI *PFN_InetPton) (INT, LPCSTR, PVOID);
typedef LPCSTR (WSAAPI *PFN_InetNtop) (INT, PVOID, PTSTR, size_t);
typedef INT (WINAPI *PFN_IfNameToIndex) (PCSTR);

Edit gio/Makefile, line 854.  Make it: PYTHON = "/c/Program Files/Python36/python"

Edit glib/gstrfuncs.c, line 1286 to have this code:

g_strlcpy (buf, strerror (errnum), sizeof (buf));
msg = buf;

glib needs libffi 3.0 or above: ftp://sourceware.org/pub/libffi/

glib needs libcpre 8.13 or above: https://www.pcre.org/

./configure --enable-unicode-properties
