cmath file not found

[skumarcm]

I am trying to compile my react native application on iOS that makes use of react-native-material-kit

Following is the configuration:
RN : 62.2
React: 16.11
react-native-material-kit: 0.6.0-beta.1
Platform: iOS

I am getting the followings Error while trying to compile and run the app on my iPhone from Xcode:
'cmath' file not found in the file: Pods/Flipper-folly/Math.h

This is caused by the following "include" directive in "node_modules/react-native-material-kit/iOS/RCTMaterialKit/TickView.m:9"

Has any one faced this issue?

Same here

[tsabend]

Yea same. It’s preventing me from upgrading a rn project and appears to be an issue with how this library is packaged. Any chance we can get an update?

[mbdebbeler]

Same. I also tried:

• :modular_headers => true

• manually adding react-native-material-kit to the project

• switching my C++ dialect and library in build settings

No dice, still getting 'cmath' file not found, coming from the same place as above.

Same. Solved it by disabling flipper for the moment because we won't use it.

[cristinaITdeveloper]

Same problem for me

[sospedra]

Same thing. Also tried a myriad of things. Also, we have flipper in place. Maybe these 2 don't play well together.

@dfeliz How did you disable flipper? The only way I can see to disable it involves changing a ton of files.

This is the library I used instead: https://callstack.github.io/react-native-paper/index.html.
As I was using the MKTextField from react-native-material-kit I could import similar component from react-native-paper.
Hope this library can help someone :).

@tastycode you need to make the following changes to disable Flipper for now:-

PodFile(remove following) -

def add_flipper_pods!(versions = {})
  versions['Flipper'] ||= '~> 0.33.1'
  versions['DoubleConversion'] ||= '1.1.7'
  versions['Flipper-Folly'] ||= '~> 2.1'

  versions['Flipper-PeerTalk'] ||= '~> 0.0.4'

  pod 'FlipperKit/FlipperKitReactPlugin', versions['Flipper'], :configuration => 'Debug'
  # List all transitive dependencies for FlipperKit pods

  pod 'FlipperKit/FlipperKitLayoutTextSearchable', versions['Flipper'], :configuration => 'Debug'
  pod 'FlipperKit/FlipperKitNetworkPlugin', versions['Flipper'], :configuration => 'Debug'
end
# Post Install processing for Flipper
def flipper_post_install(installer)
  installer.pods_project.targets.each do |target|
    if target.name == 'YogaKit'
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.1'
      end
    end
  end
end



  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
#  add_flipper_pods!


flipper_post_install(installer) 

AppDelegate.m(remove following)

#if DEBUG
#import <FlipperKit/FlipperClient.h>
#import <FlipperKitLayoutPlugin/FlipperKitLayoutPlugin.h>
#import <FlipperKitUserDefaultsPlugin/FKUserDefaultsPlugin.h>
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>
#import <SKIOSNetworkPlugin/SKIOSNetworkAdapter.h>
#import <FlipperKitReactPlugin/FlipperKitReactPlugin.h>

static void InitializeFlipper(UIApplication *application) {
  FlipperClient *client = [FlipperClient sharedClient];
  SKDescriptorMapper *layoutDescriptorMapper = [[SKDescriptorMapper alloc] initWithDefaults];
  [client addPlugin:[[FlipperKitLayoutPlugin alloc] initWithRootNode:application withDescriptorMapper:layoutDescriptorMapper]];
  [client addPlugin:[[FKUserDefaultsPlugin alloc] initWithSuiteName:nil]];
  [client addPlugin:[FlipperKitReactPlugin new]];
  [client addPlugin:[[FlipperKitNetworkPlugin alloc] initWithNetworkAdapter:[SKIOSNetworkAdapter new]]];
  [client start];
}
#endif



  #if DEBUG
    InitializeFlipper(application);
  #endif

Let me know if it works.

Temporary fix

Replace in file "react-native-material-kit"/TickView.m - "math.h" to <math.h>
