To compile PJSIP library for iPhone device, I am using this code
make distclean && make clean
ARCH='-arch arm64' ./configure-iphone --enable-opus-codec
make dep
make
This code allows me to install my app for single architecture only. To compile pjsip for all the architectures (armv7, armv7s, arm64, i386, x86_64), Which command or tool I can use
回答1:
Steps to compile for all devices.
- compile for all devices separately
- merge with lipo
eg.
-create /libsrtp-arm64-apple-darwin_ios.a /libsrtp-i386-apple-darwin_ios.a -output output_file_name
then use output_file_name.a as a universal library for all device and simulator
to check supported architecture : output_file_name.a
lipo -info name_of_static_lib
output :
/libsrtp-universal-apple-darwin_ios.a are: armv7 armv7s i386 x86_64 arm64
Compile PJSIP 2.5 Library for all archietectures
Thanks

--- One Way to build PJSIP libraries --- test with pjsip 2.6
//Updated for XCode 8.
Building PJSIP
$ cd /Users/ravimalviya/Developer/Dev2/trunk
//If you want to specify the minimum supported iOS version
//export MIN_IOS="-miphoneos-version-min=8.0"
Compile Library and Build For Default iPhone 4 use armv7 architecture
$ ./configure-iphone && make dep && make clean && make
Build For iPhone 5, use armv7s architecture
$ ARCH='-arch armv7s' ./configure-iphone && make dep && make clean && make
Build For iPhone 5s, use arm64 architecture
$ ARCH='-arch arm64' ./configure-iphone && make dep && make clean && make
Build For Simulator, use i386 architecture
export DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer
ARCH="-arch i386" CFLAGS="-O2 -m32 -mios-simulator-version-min=5.0" LDFLAGS="-O2 -m32 -mios-simulator-version-min=5.0" ./configure-iphone
make dep && make clean && make
Build For Simulator, use x86_64 architecture
export DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer
ARCH="-arch x86_64" CFLAGS="-O2 -m32 -mios-simulator-version-min=5.0" LDFLAGS="-O2 -m32 -mios-simulator-version-min=5.0" ./configure-iphone
make dep && make clean && make
The compilation result
pjlib/lib
pjlib-util/lib
pjmedia/lib
pjsip/lib
pjnath/lib
third_party/lib
Note add into project..
Combine resulting archtecture(arm64,armv7,armv7s,i386, x86_64) supported library .a file.
//goto directory where you collect all build library. create folder name arm64, armv7s, armv7, i386, x86_64 and put all library respectivly. each having only one arch supported library file.
//rename file in all these 5 folders it's a easy way to make universal library.
//Also create folder named unified where all unversal library will create.
$ export LIB_NAME="libg7221codec.a"
$ lipo -arch armv7 armv7/$LIB_NAME -arch armv7s armv7s/$LIB_NAME -arch arm64 arm64/$LIB_NAME -arch i386 i386/$LIB_NAME -arch x86_64 x86_64/$LIB_NAME -create -output unified/$LIB_NAME

Note: Unversal libraries you can add into your project and also mention in library search path.
//In order to use the pjsip libraries, we need to include folder that ahve header files that access .a files. Naturally, the header files are located in:
pjlib/include
pjlib-util/include
pjmedia/include
pjnath/include
pjsip/include
Note: do't add into project..buz you can not import like import <pjsip-lib/pjsip.h>
so just place these folder into project directory where ever you want but mention in header search path.
Enjoy (:)

We wrote a cocoapod that will create a static library that you can include in your project. For the moment you can only use it in an Objective C cocoapod environment. We are working on a version that will create a dynamic library so it can be used with Swift.
Please check it out on:
https://github.com/VoIPGRID/Vialer-pjsip-iOS
We've made an open source wrapper that makes integrating PJSIP in your iOS project a lot easier:

the merge like this as posted
lipo -create /My\ Project/pjsip-universal/x86_64/libgsmcodec-x86_64-apple-darwin_ios.a /My\ Project/pjsip-universal/i386/libgsmcodec-i386-apple-darwin_ios.a /My\ Project/pjsip-universal/armv7s/libgsmcodec-armv7s-apple-darwin_ios.a /My\ Project/pjsip-universal/armv7/libgsmcodec-armv7-apple-darwin_ios.a /My\ Project/pjsip-universal/arm64/libgsmcodec-arm64-apple-darwin_ios.a -output /My\ Project/pjsip-universal/universal/libgsmcodec-universal-apple-darwin_ios.a
finally test it
lipo -info /My\ Project/pjsip-universal/libgsmcodec-universal-apple-darwin_ios.a
output: Architectures in the fat file: /My Project/pjsip-universal/libgsmcodec-universal-apple-darwin_ios.a are: i386 armv7s armv7 x86_64 arm64
Once you generate the universal architecture:

Hope this will help you.

You can check this project on GitHub, its author did a great job of building pjsip for all architectures, he even provided podspec for easy CocoaPods integration.
回答6:
I am using this script to build pjsip for my archs.
I am running it in the pjsip root folder, it creates a uni folder containing the resulting libraries which I then link/add into my project.
#!/bin/bash
ARCHS="armv7 armv7s arm64"
mkdir -p uni
echo "Compiling..."
for arch in $ARCHS
do
echo $arch
echo "=================================="
echo
ARCH="-arch $arch" ./configure-iphone && make dep && make clean && make
echo "Done."
echo
done
RESULT_PATHS="pjlib/lib pjlib-util/lib pjmedia/lib pjsip/lib pjnath/lib third_party/lib"
for path in $RESULT_PATHS
do
echo $path
for file in `ls $path/*-armv7-*`
do
library=`echo $file | sed "s/-armv7-\(.*$\)//g"`
library_tail=`echo $file | sed "s/.*-armv7-//g"`
lipo -arch armv7 $library-armv7-$library_tail -arch armv7s $library-armv7s-$library_tail -arch arm64 $library-arm64-$library_tail -create -output $library.a
cp -vi $library.a uni
done
done
