Can't use this tool

For first I tried to install all dependencies (on Windows). I already have python version 3.6, already have cmake and webp lib.
So I install msys, add to path, from msys console install all dependencies (pacman commands) + what you wrote to fix dynamic link bug.
But on mingw make command I stucked:

So, does I do something wrong? Or it not issue with me? And how can I fix that?

[Benny-]

Thank you for filing this bug request. Let's first start with the first problem in the cpp file. Nothing will work if the prerequisites are not not. I've checked online and the following should be included to have memset and memset defined:

#include <cstring>

Can you add this line to apngdis.cpp near the other includes at the top and report back if this solved the problem or give us a new error log.

cstring might have been included in other headers for other compiler versions. That might explain why it has worked so far.

[XCanG]

Ok, in C:\apng2webp-master\apng2webp_dependencies\apngdisraw\apngdis.cpp now I have following includes:

#include <stdio.h>
#include <iostream>
#include <fstream>
#include <stdlib.h>
#include <vector>
#include <cstring>
#include "png.h"     /* original (unpatched) libpng is ok */
#include "zlib.h"
#include "json/writer.h"

Now the log:

P.S. May be if you wan't faster responces you may meet me in Discord and write instructions in realtime instead of waitng respose here. If so, then join here and PM me (I have same nickname).

Discussed with OP in discord.

The following generated linker command generates all the errors and does not include anything to link jsonpp or libpng. The Linux equivalent does.

C:\MinGW\bin\g++.exe -Wl,--whole-archive CMakeFiles\apngdisraw.dir/objects.a -Wl,--no-whole-archive -o apngdisraw.exe -Wl,--out-implib,libapngdisraw.dll.a -Wl,--major-image-version,0,--minor-image-version,0 @CMakeFiles\apngdisraw.dir\linklibs.rsp

Some command line parameters have been tried (-L C:\msys64\mingw64\lib\ -lpng). So far nothing made a difference.

The last param is a response file. It might have contained the linker commands.
