<div>I finally installed Flopcpp on cygwin with the help of</div>
<div>&nbsp;</div>
<div>&gt;&gt; ./configure -C --enable-doscompile </div>
<div>&nbsp;</div>
<div>instead of</div>
<div>&nbsp;</div>
<div>&nbsp;&gt;&gt;./configure</div>
<div>&nbsp;</div>
<div>The subsequent steps </div>
<div>&gt;&gt;make</div>
<div>&gt;&gt;make test</div>
<div>&gt;&gt;make install</div>
<div>&nbsp;</div>
<div>were successful too but when I am making an example I get the following error:</div>
<div>&nbsp;</div>
