<p>Hi Matthias,</p>
<p><br>
</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>
<p><br>
</p>
<p></p>
<div>CPPFLAGS += -m64LDFLAGS += -m64ifneq ($(OPT),opt-gccold)ifneq ($(OPT),dbgOFLAGS += -mtune=native # -malign-double -mcpu=pentium4 endif<br>
endif</div>
<div><br>
</div>
<div>ifeq ($(SHARED),true)<br>
LIBBUILDFLAGS += -D_WIN64 += -m64<br>
endif<br>
</div>
<br>
<p></p>
<div>When I tried using LEGACY=true I got the following error:</div>
<div><br>

<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>
Matthias<br>

<p>I have been trying to compile SCIP on windows using Cygwin. So I downloaded scipoptsuite-3.2.1. Once I untar it and try to built it using make I get the following error when it tries to build the Soplex library:</p>
