I do not believe version 4.1 will solve your problem. Are you using v3.3 and trying to upgrade to 4.2?Paulhttps://www.blogger.com/profile/13894940986452821719noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-69474556937090220452011-03-27T11:17:05.555-04:002011-03-27T11:17:05.555-04:00Hello Paul:

The installation of Quantum GIS comes with a binary of GDAL 1.8 which is based on the 4.1 version of the ECW SDK. And the newer 4.2 causes QGIS to crash. I'd like to revert back to the 4.1 SDK, but I can't find it anywhere :-(<br />Thanks,<br />MichaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-62908803052082146082011-01-12T19:26:55.139-05:002011-01-12T19:26:55.139-05:00Thank you for the information...

The ECW SDK v4.2 will replace v4.1 very soon (covering what Scott asked in a comment above). Soon after work is complete, expect to see a press release discussing the port and timetable for release. <br /><br />There are reasons, other than technical, why ECW SDK v3.3 is no longer available.

In the past, the ECW SDK has done quite well when compared to Kakadu with both encoding and decoding JPEG2000 data. But the real difference is in ECW, which is significantly faster than JPEG2000. So, the ECW SDK has fast JPEG2000 and lighting-fast ECW and the read-only SDK is free for desktop (client) use.Paulhttps://www.blogger.com/profile/13894940986452821719noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-31916072874704326952011-01-05T12:42:33.364-05:002011-01-05T12:42:33.364-05:00How does the ECW JPEG2000 library compare the the ...How does the ECW JPEG2000 library compare the the Kakadu JPEG2000 library in terms of performance?Unknownhttps://www.blogger.com/profile/08776918063234117493noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-25809743399516911292010-12-30T11:55:51.433-05:002010-12-30T11:55:51.433-05:00There are plans to port the ERDAS ECW JPEG2000 SDK...There are plans to port the ERDAS ECW JPEG2000 SDK to Linux, but no timetable yet.Paulhttps://www.blogger.com/profile/13894940986452821719noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-2890374028071569852010-12-30T06:11:07.333-05:002010-12-30T06:11:07.333-05:00Is GDAL on Linux contain ECW SDK?Is GDAL on Linux contain ECW SDK?Anonymousnoreply@blogger.com
