Integrate Linphone app to my iOS app

Question

There are about 20 questions on Linphone ios build in StackOverflow. A couple of them ask about integrating Linphone to an existing xcode project. I have followed them all.

Answer 1

To be able to build and run Linphone on a Swift project I had to the following steps:

1. Downlaod the latest SDK (with wget) from: http://www.linphone.org/snapshots/ios/liblinphone-iphone-sdk-latest.zip

2. Copy,paste and insert in the project:

   • liblinphone-sdk/apple-darwin/include
   • liblinphone-sdk/apple-darwin/lib
   • liblinphone-sdk/apple-darwin/share/images
   • liblinphone-sdk/apple-darwin/share/sounds

3. Create a Bridging-Header.h with:

   • #import <Foundation/Foundation.h>
   • #import <UIKit/UIKit.h>
   • #import <linphone/linphonecore.h>

4. Create a PrefixHeader.pch which import your Bridging-Header:

   • #import "Bridging-Header.h"

5. Integrate The following pods:

   • pod 'xmlrpc', '~> 2.3.4'
   • pod 'Tortuga22-NinePatch', '~> 0.1.1'

6. Configure the build Settings:

`

GCC_PRECOMPILE_PREFIX_HEADER = YES
GCC_PREFIX_HEADER = path/to/PrefixHeader.pch
OTHER_LDFLAGS = -ObjC $(inherited)
FRAMEWORK_SEARCH_PATHS = $(inherited)
HEADER_SEARCH_PATHS = $(inherited) ${PODS_ROOT}/Headers/Public $(PROJECT_DIR)/External/liblinphone-sdk/apple-darwin/include
LIBRARY_SEARCH_PATHS = $(inherited) $(PROJECT_DIR)/External/liblinphone-sdk/apple-darwin/lib $(PROJECT_DIR)/External/liblinphone-sdk/apple-darwin/lib/mediastreamer/plugins

`

7. Configure the macros:

`

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) HAVE_OPENH264 HAVE_SILK HAVE_SSL
OTHER_SWIFT_FLAGS = $(inherited) -D HAVE_OPENH264 -D HAVE_SILK -D HAVE_SSL

`

8. Libraries and Framework:

First add all the libs from the folder (and subfolders) liblinphone-sdk/apple-darwin/lib. Then be sure to add the following list:

Pods:

• libPods.a

Dynamic Libs:

• libz.dylib
• libiconv.dylib
• libxml2.dylib
• libsqlite3.dylib
• libc++.dylib
• libstdc++.6.dylib
• libresolv.dylib

Frameworks: (sorry I'm not sure if they are all 100% needed but this is how I managed to get the lib to build)

• AudioToolbox.framework
• UIKit.framework
• QuartzCore.framework
• OpenGLES.framework
• MessageUI.framework
• MediaPlayer.framework
• CoreGraphics.framework
• MobileCoreServices.framework
• AddressBookUI.framework
• AddressBook.framework
• SystemConfiguration.framework
• CFNetwork.framework
• AssetsLibrary.framework
• AVFoundation.framework
• CoreAudio.framework
• CoreMedia.framework
• CoreTelephony.framework
• CoreVideo.framework
• Foundation.framework
• CoreLocation.framework

How to test:

To verify that it was working, I integrated some sample code from the Linphone app and made some minor setups in my view controllers. To do so I integrated in the project the following classes:

• Utils.[h, m]
• LinphoneManager.[h, m]
• LinphoneCoreSettingsStore.[h, m]
• FastAddressBook.[h, m]
• LinphoneIOSVersion.h
• pod 'InAppSettingsKit', '~> 2.6'

PS: I had to update them in order to build without warnings or errors.

I hope this will help someone one day!

Check with below Header Search Paths. Also set Other Linker Flags -ObjC
