PJSIP

PJSIPをiPhone用にビルド

PJSIP 1.12 + Xcode 4.3

• 環境変数設定

  export DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
  export CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2
  # OpenSSL とのリンク用
  export OPENSSL=/Users/hoge/build/src/ssllibs
  export CFLAGS="-O2 -Wno-unused-label -I${OPENSSL}/include"
  export LDFLAGS="-L${OPENSSL}" 
  

• user.mak作成
  vi user.mak

  # for "ld: warning: CPU_SUBTYPE_ARM_ALL subtype is deprecated:"
  export CFLAGS += -march=armv7 -mcpu=arm1176jzf-s -mcpu=cortex-a8
  export LDFLAGS += -march=armv7 -mcpu=arm1176jzf-s -mcpu=cortex-a8
  

• config_site.h作成(編集)
  vi pjlib/include/pj/config_site.h

  #define PJ_CONFIG_IPHONE 1
  #include <pj/config_site_sample.h>
  

• ビルド

  ./configure-iphone
  make dep
  make
  

Xcodeで新規プロジェクト作成

• フレームワーク追加
  • CFNetwork.framework
  • AudioToolbox.framework
• PJSIPへの参照追加
  • libg7221codec-arm-apple-darwin9.a
  • libilbccodec-arm-apple-darwin9.a
  • libmilenage-arm-apple-darwin9.a
  • libpjsdp-arm-apple-darwin9.a
  • libspeex-arm-apple-darwin9.a
  • libsrtp-arm-apple-darwin9.a
  • libgsmcodec-arm-apple-darwin9.a
  • libpj-arm-apple-darwin9.a
  • libpjlib-util-arm-apple-darwin9.a
  • libpjmedia-arm-apple-darwin9.a
  • libpjmedia-audiodev-arm-apple-darwin9.a
  • libpjmedia-codec-arm-apple-darwin9.a
  • libpjnath-arm-apple-darwin9.a
  • libpjsip-arm-apple-darwin9.a
  • libpjsip-simple-arm-apple-darwin9.a
  • libpjsip-ua-arm-apple-darwin9.a
  • libpjsua-arm-apple-darwin9.a
  • libresample-arm-apple-darwin9.a
• あらかじめビルドしておいた OpenSSL への参照を追加
  • libcrypto.a
  • libssl.a
• Build Settings に設定を追加
  • Apple LLVM compiler 3.1 - Preprocessing
    「PJ_AUTOCONF=1」設定を追加
    これを追加しないと次のビルドエラーが発生します。
    「#error Endianness must be declared for this processor」

pjsipをiOSシミュレータ用にビルド

環境: Xcode 4.4.1

• configure-iphone を編集し、次の2行を追加

  DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer
  IPHONESDK=iPhoneSimulator5.1.sdk
  

• 次の環境変数を設定

  export CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc
  export CFLAGS="-O2 -m32 -miphoneos-version-min=5.0 -g -ggdb -g3 -DNDEBUG"
  export LDFLAGS="-O2 -m32"
  

• ビルド
  1. ./configure-iphone
  2. make dep
  3. make clean
  4. make

ビルドされたライブラリを arm 用と結合してユニバーサルバイナリを作成

export TARGET_DIR=~/pjsip/universal

export ARM_DIR=~/pjsip/arm

TARGET=pjlib; \
FILE="libpj-arm-apple-darwin9.a"; \
for f in $FILE; do lipo $ARM_DIR/$TARGET/lib/$f $I386_DIR/$TARGET/lib/$f -create -output $TARGET_DIR/$f; done
