postinstall could open "you need to XX next" file/url
|Reported by:||maphew||Owned by:|
To help people with the scenario below the ECW, MrSid and similar packages which can't be shipped complete could open up a file or url explaining what people need to next to complete the install.
One thing I am currently missing in OSGeo4W GDAL is support for ECW and
MrSID -- is it available? I've installed the gdal-ecw and gdal-mrsid packages, but it seems I am missing the DLLs. E.g. when I try "gdalinfo --formats" I get complaints: ERROR 1: Can't load requested DLL: C:\OSGeo4W\apps\gdal-16\bin\gdalplugins\gdal_ECW_JP2ECW.dll 126: The specified module could not be found.
ERROR 1: Can't load requested DLL: C:\OSGeo4W\apps\gdal-16\bin\gdalplugins\gdal_MrSID.dll 126: The specified module could not be found.
Have tried this with both gdal-* and gdal16-* packages. And remembered to run gdal16.bat to activate the GDAL 1.6 environment. However, can't get ECW and MrSID support.
I suspect this is due to licensing issues. Do I need to install support for these formats separately?
Yes, you need to get the SDKs from Erdas and Lizartech.
See the GDAL supported format list for information:
I would add that the OSGeo4W package pages for these packages have additional details:
