Building Linphone SDK from source

Clone https://gitlab.linphone.org/BC/public/linphone-sdk

Update submodules

git submodule update --init --recursive

Checkout the version you want

git checkout 5.2.94

Follow Linphone SDK README's build dependencies section as needed, then build and package using the following steps.

Prepare path to our SPM git dir, and the correct version tag

export PATH_TO_SPM_DIR=~/Git/linphone/spm
export LINPHONE_VERSION=$(git describe --tags --exact-match)

Apply patches as needed

for p in ${PATH_TO_SPM_DIR}/*.patch; do patch --strip=1 --forward --input $p; done

Create cmake build dir

mkdir -p build/ && cd build/

iOS cmake build steps, with an additional copy step at the end, this is a one-liner that can be re-run to re-build and copy

cmake .. -G Ninja -DLINPHONESDK_PLATFORM=IOS -DCMAKE_BUILD_TYPE=Release -DENABLE_GPL_THIRD_PARTIES=NO -DENABLE_NON_FREE_CODECS=NO -DENABLE_VIDEO=NO -DENABLE_ADVANCED_IM=NO -DENABLE_DB_STORAGE=NO -DENABLE_VCARD=NO -DENABLE_MKV=NO -DENABLE_LDAP=NO -DENABLE_JPEG=NO -DENABLE_QRCODE=NO -DENABLE_FLEXIAPI=NO -DENABLE_LIME_X3DH=NO -DENABLE_GSM=NO -DENABLE_ILBC=NO -DENABLE_ISAC=NO \
&& cmake --build . --parallel 4 \
&& rm -rf linphone-sdk-ios-${LINPHONE_VERSION} \
&& unzip -d linphone-sdk-ios-${LINPHONE_VERSION} linphone-sdk-ios-${LINPHONE_VERSION}.zip \
&& rm -rf ${PATH_TO_SPM_DIR}/XCFrameworks/ \
&& cp -vrf linphone-sdk-ios-${LINPHONE_VERSION}/linphone-sdk*/apple-darwin/XCFrameworks/ ${PATH_TO_SPM_DIR}/XCFrameworks/ \
&& cp -vrf linphone-sdk-ios-${LINPHONE_VERSION}/linphone-sdk*/apple-darwin/share/linphonesw/* ${PATH_TO_SPM_DIR}/Sources/linphonesw/ \
&& echo 'Success!'

Android cmake build steps, the artifacts then need to be manually uploaded to Nexus

cmake .. -G Ninja -DLINPHONESDK_PLATFORM=Android -DLINPHONESDK_ANDROID_ARCHS=arm64,armv7,x86,x86_64 -DCMAKE_BUILD_TYPE=Release -DENABLE_GPL_THIRD_PARTIES=NO -DENABLE_NON_FREE_CODECS=NO -DENABLE_VIDEO=NO -DENABLE_ADVANCED_IM=NO -DENABLE_DB_STORAGE=NO -DENABLE_VCARD=NO -DENABLE_MKV=NO -DENABLE_LDAP=NO -DENABLE_JPEG=NO -DENABLE_QRCODE=NO -DENABLE_FLEXIAPI=NO -DENABLE_LIME_X3DH=NO -DENABLE_GSM=NO -DENABLE_ILBC=NO -DENABLE_ISAC=NO \
&& cmake --build . --parallel 4

Finally commit changes in the SPM repo and update Package.swift references as needed

Linphone prebuilt archives

This repo is based on: linphone-sdk-ios-5.2.94.zip

From: https://download.linphone.org/releases/ios/?C=M;O=D

For updating, use the unzip and copy command from above:

unzip -d linphone-sdk-ios-${LINPHONE_VERSION} linphone-sdk-ios-${LINPHONE_VERSION}.zip \
&& rm -rf ${PATH_TO_SPM_DIR}/XCFrameworks/ \
&& cp -vrf linphone-sdk-ios-${LINPHONE_VERSION}/linphone-sdk/apple-darwin/XCFrameworks/ ${PATH_TO_SPM_DIR}/XCFrameworks/ \
&& cp -vrf linphone-sdk-ios-${LINPHONE_VERSION}/linphone-sdk/apple-darwin/share/linphonesw/* ${PATH_TO_SPM_DIR}/Sources/linphonesw/

Finally commit changes in the SPM repo and update Package.swift references as needed

Linphone SPM source code notes

LinphoneWrapper is the standard API wrapper copied from the SDK, no modifications done to it

LinphoneWrapper.swift

These contain Linphone's CallKit integration from their app, and are modified for our calling stack

CallManager.swift ProviderDelegate.swift
