Hi everybody<br><br>I&#39;m trying to make some C# sample to connect to Libgretl. The sample seems to work ok, until I call gretl_read_native_data (oh, by the way I am using sample tat is on <a href="http://gretl.sourceforge.net/API/gretl-Data-I-O.html">http://gretl.sourceforge.net/API/gretl-Data-I-O.html</a>). I always get int 12, which by Gretl error refrence means I put the wrong filename. Here is sample code:<br>

<br>            gretl.DATAINFO pddata = (gretl.DATAINFO)Marshal.PtrToStructure(p, typeof(gretl.DATAINFO));<br>
            string fname = @&quot;D:\izhod.gdt&quot;;<br>
            StringBuilder test = new StringBuilder(fname);<br>
            double Z = 0;<br>
            int err = gretl.gretl_read_native_data(test, ref Z, ref pddata);  <br clear="all"><br>I tried to found out the source of problems, so I decided to go copy-paste of sample on gretl site. I downloaded gretl source code, downloaded Pelles - IDE for C and tried to run the program. First I get problems with refrence zlib.h, but soon as I downloaded from web, the problem was gone. But I&#39;m getting problems with winnt.h(558): fatal error #1014: #error: &quot;No target architecture&quot;.<br>

<br>Does anybody had/have same problems, or anybody got a clue what did I wrong? Any tip would be great. <br><br>Simon<br><br>
