Error 'MapboxDirections/MapboxDirections.h' file not found after installing MapboxNavigation

[paul019]

Hi there,

I've installed MapboxNavigation iOS via CocoaPods without experiencing any issues. But after compiling the project in Xcode I got two errors produced by the library. One error is 'MapboxDirections/MapboxDirections.h' file not found:

I tried to just comment out the line of code that produced the error and the whole project indeed compiled successfully. As I can evaluate the import that produces the error isn't needed in the file at all. Is this true?

After doing this hacky bugfix, I started writing some lines of Mapbox code and got another error:

The code:

import Foundation
import UIKit
import MapboxCoreNavigation
import MapboxNavigation
import MapboxDirections
  ...
let navigationService = MapboxNavigationService(route: route, simulating: .always)
let navigationController = NavigationViewController(for: route, navigationService: navigationService)
viewController.addChildViewController(navigationController);
viewController.addSubview(navigationController.view);

The resulting error:
Command failed due to signal: Abort trap: 6

I've no clue what this error means and think that it may have something to do with my hacky bugfix. Is this possible?

Mapbox Navigation SDK version: 0.22.0

@frederoni Do you have an idea how to solve this issues?

[paul019]

@frederoni An answer would be very appreciated.

Sorry about the delay.

What version of Xcode and what version of CocoaPods are you using? Do you see similar issues with newer versions of the Navigation SDK?

[paul019]

@frederoni I tried out both Xcode 9.4 and Xcode 10. But I had the same issue with both versions. To the Navigation SDK: I tried out version 0.22.0 and 0.24.0. My CocoaPods version is 1.5.3.

[frederoni]

@paul019 Can you share your Podfile? Feel free to leave out anything not relevant to Mapbox dependencies.

[paul019]

Here's my Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

target 'my-target' do
  pod 'MapboxMobileEvents',
    :git => 'https://github.com/mapbox/mapbox-events-ios.git',
    :commit => "79d29f1df5a9187481f5c9ac8fa13430d1f04139"
  pod 'MapboxNavigation', '~> 0.24.0'
  ...
end

[paul019]

@frederoni Could you find a problem with my Podfile?

[frederoni]

Add use_frameworks! below platform :ios, '9.0' and it should work.

Feel free to re-open if the issue persists.

[paul019]

@frederoni Thank you for the tip. Unfortunately, it doesn't work for me, because I am installing other Pods that throw an error when using use_frameworks!: [!] The 'Pods-pq-app-v2' target has transitive dependencies that include static binaries. Is there another possible option for me than defining use_frameworks! globally? I will also do research on whether its possible to use my other Pods with use_frameworks!...

PS: I cannot re-open the issue because you closed it (see https://stackoverflow.com/questions/21333654/how-to-re-open-an-issue-in-github). I hope you see this message anyway.

[paul019]

@frederoni So, do you have an idea, how I could install MapboxNavigation without the need to set use_frameworks!? Unfortunately, my other Pods do not support this global 'variable' at all.

[frederoni]

Specifying use_framework individually is unfortunately not something that will be supported by CocoaPods. Perhaps you could work around the issue with pod 'MapboxNavigation', :modular_headers => true but I haven't made any progress so far. However, MapboxDirections.swift seem to be the culprit. MapboxSpeech and Polyline build just fine as static frameworks.

@1ec5 static libraries wrapped in a framework is the default in CocoaPods (as of 1.5?), supported on Xcode >= 9 and iOS >= 9. Any idea why MapboxDirections.swift’s umbrella header would be missing unless use_frameworks! is specified?

[paul019]

@frederoni @1ec5 Now I've added :modular_headers => true to my Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

target 'my-app' do
  pod 'MapboxMobileEvents',
    :git => 'https://github.com/mapbox/mapbox-events-ios.git',
    :commit => "79d29f1df5a9187481f5c9ac8fa13430d1f04139"
  pod 'MapboxNavigation', '~> 0.24.0',
    :modular_headers => true
  ...
end

However, I still get the same error when running the project in Xcode after the pod repo update && pod install.

[paul019]

@frederoni An answer would be very appreciated.

[frederoni]

We don't have a solution for this issue yet. I will transfer this issue to MapboxDirections.swift and try to address it as soon as possible.

[mysport12]

We are also running into this issue on our project. use_frameworks! causes other pods to fail. We are using MapboxNavigation v0.26.0 and Cocoapods v1.5.3.

[paul019]

@frederoni When can we expect a solution to this issue?

[frederoni]

It's not a long-term solution but I was able to work around this issue by renaming MapboxDirections.swift to MapboxDirections and using the following Podfile:

Podfile

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

target 'my-app' do
  pod 'MapboxCoreNavigation', :path => '../mapbox-navigation-ios'
  pod 'MapboxNavigation', :path => '../mapbox-navigation-ios'
  pod 'MapboxMobileEvents', :modular_headers => true
  pod 'MapboxDirections', :path => '../MapboxDirections.swift', :modular_headers => true
end

along with renaming MapboxDirections.swift.podspec to MapboxDirections.podspec and edit MapboxCoreNavigation.podspec to depend on MapboxDirections instead of MapboxDirections.swift.

I know there was an issue with . in framework names in Xcode 6/7, but the bug seems to have re-surfaced, at least with static frameworks.

[paul019]

@frederoni Thank you for your answer! I'm very sorry for not answering for such a long time.

I've now tried out your workaround, but unfortunately the pod repo update && pod install fails for me, if I use your Podfile. That's the error message that is thrown in the console:

[!] No podspec found for 'MapboxCoreNavigation' in '../mapbox-navigation-ios'

So, what's the problem here?

[1ec5]

The Podfile in #318 (comment) assumes you have a clone of the dependencies’ repositories beside the current project directory.

[1ec5]

static libraries wrapped in a framework is the default in CocoaPods (as of 1.5?), supported on Xcode >= 9 and iOS >= 9. Any idea why MapboxDirections.swift’s umbrella header would be missing unless use_frameworks! is specified?

It’s unusual that MapboxDirections-Swift.h tries to import MapboxDirections.h. By contrast, the generated interface for MapboxSpeech, MapboxSpeech.h, lacks this import statement.

#import <MapboxDirections/MapboxDirections.h>

There should be no reason for a library’s generated interface header to import the same library’s umbrella header. I think this may come down to the fact that MapboxDirections.swift’s pod name (MapboxDirections.swift) doesn’t match the product module name (MapboxDirections) and possibly that it contains “.swift”, which makes it look like a file.

[aliustaoglu]

I cannot use frameworks because of other dependencies. And as per #318 (comment) I renamed MapboxDirections.swift.podspec to MapboxDirections.podspec but still no luck. I get this error:

Redefinition of module 'MapboxDirections'

[1ec5]

There should be no reason for a library’s generated interface header to import the same library’s umbrella header. I think this may come down to the fact that MapboxDirections.swift’s pod name (MapboxDirections.swift) doesn’t match the product module name (MapboxDirections) and possibly that it contains “.swift”, which makes it look like a file.

As of #400 in v1.0.0-alpha.1, the pod’s name matches the module name, so the umbrella header should no longer be broken. What’s more, this library no longer supports Objective-C, so the umbrella header likely has even less relevance.

Please check again whether the issue persists in v1.0.0-alpha.1.

Hey there, I have some issues since iOS 13.3.1 with use_frameworks!.

Is there any way to fix that issue? Unfortunately I can't load MapboxDirections/MapboxDirections.hby adding :modular_headers => true to my Podfile

That’s mapbox/mapbox-gl-native-ios#157, unrelated to the problem that was tracked in this issue.

[1ec5]

This library no longer supports Objective-C code directly. See #381 for background and a workaround if your application is still written in Objective-C.

[1ec5]

My bad, I thought the original issue was about importing the umbrella header manually, as one would in Objective-C. Still, I think the root cause mentioned in #318 (comment) is resolved as of v1.0.0-alpha.1, since we’ve removed “.swift” from the pod’s name.
