<p>Hello Matthias,</p>
<p><br>
</p>
<p>I really appreciate your help. I'm still facing difficulties. I am now able to built SCIP when I use ZIMPL=flase. However, I require ZIMPL for the python interface using make SHARED=true scipoptlib. I still get an error even when I copied the previous ZIMPL
files that you attached. The error is as follows when I run "make" (<b>without</b> setting ZIMPL = false):</p>

<div>I tried to compile without copying over your ZIMPL files and I still get an error just like in my previous message (my windows is 64 bits by the way).I require a python interface for a project I am working on so your help would be great.</div>

<div>Dear Ahmed,<br>
<br>
you did not do what I told you in my previous answer! I attached a corrected sub-makefile.<br>
<br>
For your second compiling error: The ZIMPL x86_64 sub-makefile is missing for cygwin. I attached them as well.<br>
You might consider compiling with ZIMPL=false if you can't solve the issue and don't need ZIMPL.<br>
<br>
all the best<br>
Matthias<br>

<p>Hi Matthias,</p>

<p>I tried extending "CPPFLAGS" parameter but I still get the same error. This is how I extended CPPFLAGS (I attached "make.cygwin.x86_64.gnu" above too) :</p>

<div>Dear Ahmed,<br>
<br>
for some reason the flag "_WIN32" or "_WIN64" is not set when using cygwin. You can do that manually be adjusting the corresponding sub-makefiles "make.cygwin.x86.gnu" or "make.cygwin.x86_64.gnu" in "soplex-2.2.1/make/":<br>
Simply add " -D_WIN32" or " -D_WIN64", respectively, in the first line, extending the "CPPFLAGS" parameter.<br>
<br>
Hope that helps!<br>
You might also try the make option "LEGACY=true", disabling the rational solving capabilities of SoPlex.<br>
<br>
cheers<br>
