I need to use OpenSlide in a Linux-based Docker Container.<br>
I have developed the application on Windows targeting .Net Core and it works when I launch it on my Windows machine.<br>
<br>
I have created the Docker Container but when I try to load the Windows x64 DLLs fromOpenSlide I get a "Bad IL format" error.<br>
<br>
I thought I could install the Debian version as I create the container but the command:<br>
RUN apt-get install openslide-tools<br>
gets the error:<br>
Unable to locate package openslide-tools<br>
The command '/bin/sh -c apt-get install openslide-tools' returned a non-zero code: 100<br>
<br>
I am a n00b so please forgive me.<br>

Hi, I am trying to build Openslide for Windows 10 64bit using Cygwin.<br>
<br>
I have followed the instructions in ReadMe file and I am keep running into the same error while building libpng.<br>
<br>
For Cygwin system, I currently have<br>
x86_64-w64-mingw32-gcc g++ 9.2.0 (for both)<br>
cmake 3.14.5<br>
make 4.3<br>
<br>
For python, I have python 3.7 (anaconda) installed on my system.<br>
<br>
So my question is:<br>
<br>
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?<br>
<br>
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?<br>
<br>
* MinGW-w64 gcc and g++ for the target architecture (i686 or x86_64)<br>
* NASM<br>
* OpenJDK<br>
* Apache Ant<br>
* CMake<br>
* gettext utility programs<br>
* glib2 utility programs<br>
* Native gcc and binutils for your build platform<br>
<br>
1. If it is not due to program versions, then can someone help me how to fix this error I am encountering?<br>

Failed: make $parallel (line 401)<br>
<br>
Also, in regards to the last line of error: Failed: make $parallel (line 401)<br>
<br>
I have tried to change the number of parallels using -j 1 through 4, but it did not change the result.<br>
<br>
I have also tried building with 2017 release version, 2016 version, 2015 version, but they all give me the same error.<br>
<br>
In addition, I have tried to install Openslide in my windows linux subsystem (ubuntu16.04) and it worked fine.<br>
<br>
Thank you in advance.<br>
