Wickley,
When I typed www.ermapper.com <http://www.ermapper.com/> I was led to
www.erdas.com <http://www.erdas.com/> instead. Did the same occur to
you? If so, how did you get
ImageCompressionSDKSourceCode3.3Setup_20070509.zip from www.erdas.com
<http://www.erdas.com/> ? All I got from www.erdas.com
<http://www.erdas.com/> was ecw_jpeg_2000_sdk_3_3.zip which I don't
think is the same as ImageCompressionSDKSourceCode3.3Setup_20070509.zip.
If not, how did you get to ER Mapper website?
Thanks.

Subject: Re: [Gdal-dev] Supporting ECW as a plugin on window,
Hi again,
a side note:
in the subject of your email, you are asking for "supporting ECW as a
plugin" whilst in the body of your email you are generally asking for
supporting ECW in GDAL.
The steps I have suggested in the previous email, are needed only if you
need to add ECW support as a separate plugin.
In case your aim is simply adding ECW in GDAL (without leveraging on the
"Plugin way") you can simply rebuild GDAL after having removed the
"ECW_PLUGIN = YES" line from NMAKE.opt.
Hope this help.
Regards,
Daniele

Hi,
I did a similar thing on 1.4.4 and 1.5.3.
Basically, you are building ECW driver as a plugin as stated by the flag
ECW_PLUGIN = YES
Therefore, you need to do a separate build of the ECW GDAL Driver.
Go in gdal/frmts/ecw and run "nmake /f makefile.vc plugin"
This command should produce a gdal_ECW_JP2ECW.DLL.
Finally you need to define a GDAL_DRIVER_PATH environment variable
linking to the location where you have built gdal_ECW_JP2ECW.DLL.
After this, gdalinfo should find the ECW driver.
Let me know if you have additional issues, since I did these steps on
1.4.4 which needed some fixes that I have copied from 1.6.0 code. (I
guess 1.6.0 already contains all the proper declarations)
Regards,
Daniele

Hello , I have some question about supporting ECW in gdal.but I can not
solve it. My step is following:
1.I download gdal-1.6.0 and
ImageCompressionSDKSourceCode3.3Setup_20070509.zip from ERMaper webset
and
Windows Server 2003 R2 Platform SDK from microsoft website.
2. I set up Windows Server 2003 R2 Platform SDK on my computer in
D:\Program
Files2.
3. I unzip the ImageCompressionSDKSourceCode3.3Setup_20070509.zip,and
select
E:\libecwj2-3.3
\Source\NCSBuildQmake\libecwj2_win32_net_shared.vcproj,using visual
studio 2005.When open the file,
it needs translate, and it translates well with no error and just two
warnings.
4. I set visual studio 2005 project->c/c++->general ->include
directory,and
add D:\Program Files2\Microsoft Platform SDK for Windows Server 2003
R2\Include
5. I select debug,win32 ,and build libecwj2.dll successfully,and it is
included in E:\libecwj2-3.3\Source\NCSBuildQmake\Debug
6. I unzip gdal-1.6.0 to E:\gdal-1.6.0. change MSVC_VER=1400 .
7. for ECW support, I Uncomment the following and update to enable ECW
support.
# Uncomment the following and update to enable ECW support.
ECW_PLUGIN = YES
ECWDIR = E:\libecwj2-3.3
ECWLIB = $(ECWDIR)\Source\NCSBuildQmake\Debug\libecwj2.lib
8. open E:\gdal-1.6.0\frmts\leveller\levellerdataset.cpp,and change {
"?,
kPI / 180.0, UNITLABEL_DEGREE } to
{ "?", kPI / 180.0, UNITLABEL_DEGREE }
9. I start visual studio 2005 commandline , and change the path to
E:\gdal-1.6.0, then ,I inputs command nmake /f makefile.vc,nmake /f
makefile.vc install and nmake /f makefile.vc devinstall.
10. I copy gdal16.dll to C:\WINDOWS\system32.
11. I set tools->options->projec and solution -> vc++ direction
->includingfile->C:\warmerda\bld\include
->libraries->C:\warmerda\bld\lib
12.I build a new project,and code following:
#include "gdal_priv.h"
#include "stdio.h"
#include "gdal.h"
#pragma comment(lib, "gdal_i.lib")
int main()
{
const char *p=NULL;
GDALDataset *poDataset=NULL;
GDALDriver *pDriver=NULL;
GDALAllRegister();
int t =GDALGetDriverCount();
printf("%d\n",t);
for(int k=0;k<t;k++)
{
const char *pt=NULL;
pDriver=(GDALDriver *)GDALGetDriver(k);
pt=pDriver->GetDescription();
printf("%s\n",pt);
}
}
result:
