Hi Wolfgang,
sorry that this is causing trouble to you.
QMS for Windows sets GDAL_PATH by purpose to the path where the GDAL
libraries are put by the Windows installer.
This avoids potential trouble if multiple GDAL versions are installed.
I recommend not to change this as we already had enough of this trouble
in the past.
If you want QMS to us an alternative GDAL, then you have to _replace_
the GDAL provided by the installer with your own.
If you think that the directory structure created by the installer is
not compatible with standard GDAL installations, then we can change it -
both in the installer and in IAppSetup.cpp.
Best regards,
Helmut

Hallo Oliver,
there is a point that can cause the discussed trouble:
- I start QMS from a console window. This console window has an
environment. Part of it says:
d:\Temp\QMSFiles>set gdal_data (query value of
environment variable!)
GDAL_DATA=d:\Temp\QMSFiles\gdal-data (query result)
(Mitchels proposal - variable points to a "patched" GDAL)
- The Windows rule is that this value of an environment variable is
given to the application, i.e. using the GDAL_DATA environment variable
within QMS started from this console should use
"d:\Temp\QMSFiles\gdal-data". This rule is, of course, assumed to be
valid for Mitxels BAT script.
- Now look at the QMS logfile:
2017-08-07 17:26:39.072 [debug] "GDAL_DATA directory set to
d:\\Temp\\QMSFiles\\data"
Obviously a wrong path! This could explain everything! The "standard"
GDAL doesn't support ECW!
Do you have an explanation for the difference? If I understand
IAppSetup.cpp correctly, then with the statement "qputenv("GDAL_DATA",
gdalDir.toUtf8())" Qt is asked to give the value of the environment
variable GDAL_DATA.
Where does the result come from? I don't have a global environment
variable GDAL_DATA. Does QMS make an implicit assumption about the
location of the GDAL files?
Greetings

Sounds like something else is wrong. Maybe Mitxel has another idea. Is
there
any debug output?

Hi Oliver,
I'm sorry - I recompiled QMS and now I got
2017-08-06 17:22:41.976 [debug] VRT: try to open "D:/GPS/Maps/euecw.vrt"

But: no map visible. Neither an overview, nor a normal map. I checked
zoom levels from 10m to 1000km. Im still working with Mitxels path
settings and the GDAL recommended there.

Hi Wolfgang,
are you sure you use the latest version with that patch? What you
describe
would fir with QMapShack prior to the patch.
