Ok. Now I have downloaded the library required to build GDAL with HDF4 support.<br><br>But now I have another question.<br><br>The HDF42r1 folder contains two subdirectories:<br>&nbsp;&nbsp;&nbsp; DLL which contains:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hd421m.dll
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hd421m.lib<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hm421m.dll<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hm421m.lib<br><br>and LIB which contains:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hd421.lib<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; hm421.lib<br><br>How I need to configure the NMAKE.OPT?<br>I'm talking about the second options of the HDF4 support section (HDF4_LIB).
<br><br><br><br># Uncomment the following and update to enable NCSA HDF Release 4 support.<br>HDF4_DIR =&nbsp;&nbsp;&nbsp; c:\work\HDF42r1<br>HDF4_LIB =&nbsp;&nbsp;&nbsp; /LIBPATH:$(HDF4_DIR)\lib Ws2_32.lib<br><br><br><br>There is no Ws2_32.lib in the HDF42r1's lib directory.
<br>Which of the previously introduced *.lib I need to set in this option?<br><br>Thanks a lot.<br><br>-- <br>Best Regards,<br>Daniele<br><br><div><span class="gmail_quote">On 7/13/06, <b class="gmail_sendername">Daniele Romagnoli
