undefined reference to `__memcpy_chk' while building Openslide

[Jang, Jun H.]

Hi, I am trying to build Openslide for Windows 10 64bit using Cygwin.

I have followed the instructions in ReadMe file and I am keep running into the same error while building libpng.

For Cygwin system, I currently have
x86_64-w64-mingw32-gcc g++ 9.2.0 (for both)
cmake 3.14.5
make 4.3

For python, I have python 3.7 (anaconda) installed on my system.

So my question is:

  1.  To build Openslide, do I need Python installed on my computer? If so, how do I specify an environment that Cygwin can work with?

  2.  From what I am searching online and seeing in the command prompt, it seems like its most likely due to a version issue with the package version of programs such as make, cmake, mingw64 gcc, etc. Can someone provide me with a working versions of each necessary programs?

  *   MinGW-w64 gcc and g++ for the target architecture (i686 or x86_64)
  *   NASM
  *   OpenJDK
  *   Apache Ant
  *   CMake
  *   gettext utility programs
  *   glib2 utility programs
  *   Native gcc and binutils for your build platform

  1.  If it is not due to program versions, then can someone help me how to fix this error I am encountering?

Failed: make $parallel (line 401)

Also, in regards to the last line of error: Failed: make $parallel (line 401)

I have tried to change the number of parallels using -j 1 through 4, but it did not change the result.

I have also tried building with 2017 release version, 2016 version, 2015 version, but they all give me the same error.

In addition, I have tried to install Openslide in my windows linux subsystem (ubuntu16.04) and it worked fine.

Thank you in advance.
