Demo Crash

[dimohamdy]

There is exception when demo try to make route and this message apper
"graphHopperLocation is not specified. call init before"

graphHopperFolder is nil please help me

[clns]

The "graphHopperLocation is not specified. call init before" error is in the GraphHopperTest.java#L397 file, which is part of the test suite and the iOS project doesn't call that.

• At what point do you get this error?
• What method are you following to get started, the main instructions or the sample app?
• If possible, please provide a stack trace with the error.

[dimohamdy]

When i run the sample App
in this method [_hopper load__WithNSString:location];

• (jboolean)load__WithNSString:(NSString *)graphHopperFolder ;

This looks like a graph data import issue. If you imported the data as described in the sample app, make sure you have all the Requirements, especially Maven. Check if the import succeeded by running ls -l graphhopper/graph-data.osm-gh/ in the repository root, which should show something like this:

$ ls -l graphhopper/graph-data.osm-gh/
total 204912
-rw-r--r--  1 calin  staff    50M Apr 20 20:57 edges
-rw-r--r--  1 calin  staff    26M Apr 20 20:57 geometry
-rw-r--r--  1 calin  staff    12M Apr 20 20:56 location_index
-rw-r--r--  1 calin  staff   2.0M Apr 20 20:57 names
-rw-r--r--  1 calin  staff    10M Apr 20 20:57 nodes
-rw-r--r--  1 calin  staff    32K Apr 20 20:57 properties

If you don't have this then most probably your import failed and you need to reimport the data.

If everything checks out, try running everything again, from scratch. Below is the sequence of commands I just ran successfully on my local machine. They are exactly like in the docs but I wrote them here for convenience. Watch out for any errors.

$ git clone --recursive https://github.com/graphhopper/graphhopper-ios.git
$ cd graphhopper-ios
$ ./graphhopper-ios-sample/import-sample.sh
$ curl -L -o j2objc-0.9.6.1.zip "https://github.com/google/j2objc/releases/download/0.9.6.1/j2objc-0.9.6.1.zip" && unzip j2objc-0.9.6.1.zip && mv j2objc-0.9.6.1 j2objc && rm j2objc-0.9.6.1.zip
$ open graphhopper-ios-sample/graphhopper-ios-sample.xcodeproj
# in Xcode, Build & Run on Simulator

[dimohamdy]

graph-data.osm-gh my file is graph-data.osm.pbf

[clns]

graph-data.osm.pbf is the raw data file from http://download.geofabrik.de/ and if you don't have the other files it means you didn't import the data into GraphHopper. Try running the import again using ./graphhopper-ios-sample/import-sample.sh and then check if the import succeeded as described above.

[dimohamdy]

i have graph-data.osm.pbf how i can make it as graph-data.osm-gh

[clns]

By running ./graphhopper-ios-sample/import-sample.sh.

[dimohamdy]

when i run it

Downloading http://download.geofabrik.de/europe/romania-latest.osm.pbf

[clns]

If the download starts it means you don't have it in the right place. However that's fine, after the download finishes the graph data will be created automatically and you can start playing with it in Xcode. There are instructions for importing Germany as well in the sample app.

[dimohamdy]

in xcode i will import romania-latest.osm.pbf file?

[clns]

Yes, by default the import script imports romania-latest.osm.pbf, so you can only create routes within Romania. This is just an example, you can follow the instructions on the sample app to import any country you want.

[dimohamdy]

i found the problem in marven ,did it take time when convert
Thanks

[dimohamdy]

i still have problem but from marven Now

[clns]

I'm not familiar with Maven, it is used by GraphHopper as its build system. Try google-ing the errors to see if you can find something useful. This popped up on a very quick search, not sure if it will be of any help.

As this error is not related to graphhopper-ios but core graphhopper maybe @karussell would know why Maven is complaining.

[dimohamdy]

thanks Again I try in it

[karussell]

It looks, like some HTTPS/host problems with maven central. Maybe you just try it again? If that does not help try what was suggested in @clns its link: rm -rf <home>/.m2/repository or even rm -rf <home>/.m2/

[karussell]

How was this fixed? @dimohamdy

[dimohamdy]

I install Maven that use to convert graph-data.osm.pbf to graph-data.osm-gh
