not able to use mapnik in tiler about ga-worldwind-suite HOT 6 OPEN

Do you have the .net framework installed? You need .net framework 4 for it to work.

from ga-worldwind-suite.

yes .. I have already installed .net framework 4

from ga-worldwind-suite.

Hi,

This is a tricky one - I haven't been able to reproduce it.

Have you confirmed the map.xml file you are selecting is a valid mapnik document? It may be that the tiler is not reporting the error correctly. Is there any additional error output in the log panel or console window? Are you able to run Nik2Img.exe on its own from the command line? (it is located in the \mapnik directory)

Could you please post details of your system configuration (Operating system, service packs, .NET framework version, java version). It may help isolate the problem.

Cheers,

Hi Bharti,

Have you tried running Nik2Img.exe with valid command line arguments? The minimum arguments are -m and -o. Does it work? Or does it fail with the same error as reported in the Tiler application?

The missing DLL message looks like its a DLL search path problem. You may have one of the DLLs either already loaded from somewhere else or in your System32 folder etc. You could try using something like dependency walker (http://www.dependencywalker.com/) to inspect where the DLLs are being loaded from. Alternatively, try doing a search of your System32 folder for the DLLs contained in the mapnik directory.

Hope this helps.

Hi James

I have tried to run Nik2Img with command line by giving the following commnad--

Nik2Img.exe -m "E:\ga\ga-m3dv-ga-worldwind-suite-d717c37\Tiler\mapnik_example\map.xml" -e

but it is giving the same error .
See System32 folder but could not find mapnik_c.dll
also use dependency walker but nothing found.
