Console redirection fails

[jolly47roger]

I raised a support ticket #5073. I thought it had been resolved but it has not. I have, however, got closer to the problem.

My program invokes GDALINFO to extract the projection and other information from a GEOTIF. I redirect the console so that the program can analyse and act on the information returned.

This works correctly with GDAL 110-1600-x64 core.

But if I install the ECW extension for this version then console redirection stops. If I uninstall the ECW extension it works correctly again. The MrSid extension works OK

I am running windows 7 64 bit, but this also happens with XP 32bit

Confirmed here. Renaming the driver bin\gdal\plugins\gdal_ECW_JP2ECW.dll activates the output again.

Hum, this is an interesting (=annoying) issue. Here's the result of my tests
(only on 32 bit builds) :
- release-1600-gdal-1-10-mapserver-6-2 : bad
- release-1600-gdal-1-9-1-mapserver-6-0-3 : bad
- release-1400-gdal-mapserver (latest dev version): bad
- release-1500-gdal-mapserver (latest dev version): bad
- release-1400-gdal-1-8-1-mapserver-6-0-1 : bad
- release-1310-gdal-mapserver (latest dev version): ... good ...
- release-1310-gdal-1-8-1-mapserver-6-0-1 : good

So my conclusion is that it does not depend on the GDAL version, but it does
depend on the MSVC compiler. And apparently only MSVC 1310 pleases the ECW SDK.
The issue must be a bad interaction between the old ECW SDK 3.3 code and MSVC >=
1400.

I've reported it as https://github.com/gisinternals/buildsystem/issues/36 to
Tamas as this is more a packaging issue, but I'm not sure what can be done in
practice. Unless someone is willing to debug that. Perhaps the issue has gone
with newer versions of the ECW SDK.

Closing this ticket. This is a SDK 3.3 bug. Nothing we can probably do about that
