GeoJSONSource missing (Use of undeclared type 'GeoJSONSource')

[jerzykiler]

Hello,

I am trying to complete the Styled GeoJSON tutorial from the main page and when I declare a GeoJSONSource type variable I get an error:

    var landUseSource: GeoJSONSource?        // ! Use of undeclared type 'GeoJSONSource'

I have set up the HelloEarth project with binary distribution.

Should I do something more to get the GeoJSONSource type visible or am I doing something wrong ?

Cheers

It looks like GeoJSONSource is under vector_tiles now and won't appear in the binary version. Best to set things up with a submodule for now.

[jerzykiler]

I have wired up everything from sources now and added

#import "vector_tiles/GeoJSONSource.h"

to MaplyBridge.h

and now the build fails with the information 'MaplyComponent.h' file not found in GeoJSONSource.h file

#import "MaplyComponent.h"    // 'MaplyComponent.h' file not found

[jerzykiler]

Ok i fixed that with: #import "../MaplyComponent.h"

but now

it fails with:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_GeoJSONSource", referenced from:
      objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

[jerzykiler]

Ok I fixed it by adding generated WhirlyGlobeMaplyComponent.framework under Build Phases to Link Binary With Libraries

but now it fails with some C errors ?:

Ok I fixed it by adding

import <libxml/parser.h>

at the top of KissXML/DDXMLDocument.m

but now it fails with other errors:

/Users/damian/repos_learning/WhirlySources/WhirlySources/libs/WhirlyGlobeMaply/WhirlyGlobeSrc/local_libs/aaplus/AADynamicalTime.cpp:625:3: error: expected '}' { 2457937.00, 69 }, //2017.5 ^ /Users/damian/repos_learning/WhirlySources/WhirlySources/libs/WhirlyGlobeMaply/WhirlyGlobeSrc/local_libs/aaplus/AADynamicalTime.cpp:88:1: note: to match this '{' { ^ /Users/damian/repos_learning/WhirlySources/WhirlySources/libs/WhirlyGlobeMaply/WhirlyGlobeSrc/local_libs/aaplus/AADynamicalTime.cpp:698:34: error: invalid application of 'sizeof' to an incomplete type 'const DeltaTValue []' size_t nLookupElements = sizeof(g_DeltaTValues) / sizeof(DeltaTValue); ^~~~ 2 errors generated.

Why am I getting these errors ? Should I get them or is there some magical bash script that fixes them for me ? Did I do something wrong ?

[mousebird]

An Objective-C file probably doesn't like C++ would be my guess. I'm not sure where this has gone.

The submodule approach should compile fine, as should the Cocoapod out of the develop branch.

[jerzykiler]

It compiles fine if I don't change anything.

But if I add `

import "vector_tiles/GeoJSONSource.h"

to the bridging header, so I can useGeoJSONSource`, those errors appear.

Should I do something else with GeoJSONSource.h to get it working ?

[mousebird]

It depends on what you're compiling against. If you're using a precompiled binary the vector_tiles may not be in there. If you're using a submodule you need to define the constant NOTPODSPECWG and it should pull in those header.

[jerzykiler]

Thanks, it worked :)
