Hi,
I have gotten an error complaining that a specific method/entry point has not been found in dynamically linked library in the GDAL_HOME/bin directory. I have encountered it when following Step 4 - Check the gdal version and for that specific executable (gdalinfo.exe) it was entry point SSL_getO_group_name inside libcurl.dll.
I have noticed that in the GDAL_HOME directory, there is also a SDKShell.bat script that is mentioned in read-me.txt to be ran to setup the environment. After doing that, the error went away.
Thanks for a great tutorial.
