<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>thanks for your quick reply. As you guessed, I
don't have MS Visual C++. I'll try the "kitchen sink" builds again (last time I
think it lagged the ecw support).</FONT></DIV>
<DIV><FONT face=Arial size=2>Looking forward to the new version of
FWtools.</FONT></DIV>

<DIV><FONT face=Arial size=2>In the past a baseline GDAL has generally built
fairly successfully<BR>on cygwin/gcc. However, gcc has radically different
C++ name<BR>mangling than MS VisualC++ so it is essentialliy impossible to
call<BR>MS style C++ DLLs like the ECW and MrSID ones from a Cygwin<BR>style
build of GDAL. <BR> <BR>> Reason I'm trying this is that I'm
desperate for a gdal dll that supports<BR>> mrsid and ecw. I've got one that
does either, but not both......<BR>> Unfortunately, I haven't got any other
platform for compiling. I'm not<BR>> particularly experienced in compiling,
but if I know it's possible in<BR>> cygwin, I won't give up. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I gather you don't have access to MS Visual
C++? I think they <BR>do have some sort of unoptimizing version of it
available for free<BR>download. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, I think you will find that Howard Butlers
"kitchen sink" <BR>binaries for win32 of mapserver include a GDAL built
with<BR>MrSID and ECW support though I am not sure ... and it is<BR>possible
that Howard's binaries lag the recent MrSID<BR>improvements.
<BR> <BR>Finally, I am hoping to include MrSID support as an add on<BR>to
the FWTools builds soon. </FONT></DIV>
