为iPhone for arm64的pjsip构建libyuv

Question

我一直试图为arm64架构构建利比亚，然后将其集成到PJSIP库中。但是我没有得到任何进展，因为Pjsip无法找到libyuv.a框架。

在配置Pjsip构建时，我使用以下命令：

ARCH='-arch arm64' ./configure-iphone --with-libyuv=/Users/Mayur/Desktop/pjsip/externals/libyuv/out_ios/Release-iphoneos

这是libyuv.a所在的文件夹。

但是，在配置时，出现了以下一行：

checking for I420Scale in -lyuv... no

对这里出什么问题有什么建议吗？

参考资料：

1. 为iPhone：https://trac.pjsip.org/repos/wiki/Getting-Started/iPhone构建Pjsip
2. 构建libyuv：https://trac.pjsip.org/repos/ticket/1776

更新

我就是这样建立libyuv.a的

1. GYP_DEFINES="OS=ios target_arch=arm64 target_subarch=arm64“GYP_CROSSCOMPILE=1 GYP_GENERATOR_FLAGS="output_dir=out_ios”/gyp_libyuv -f忍者--深度=。libyuv_test.gyp
2. 忍者-j7 -C out_ios/Release libyuv_unittest

这成功地创建了库，但我没有找到连接这个库的正确方法！

Answer 1

事实证明，如果您使用PJSIP的最新版本并安装问题中所描述的libyuv框架，那么它的构建就会非常完美。

只需使用以下命令查看修订后的5128：

svn checkout -r 5128 http://svn.pjsip.org/repos/pjproject/trunk pjproject

它还包含iOS中的定向修复！

Answer 2

使用以下脚本构建PJSIP库。

步骤：

1. 复制脚本并制作.sh文件。
2. 在PJSIP文件夹中复制.sh文件。
3. 运行chmod 777 .sh_filename
4. 运行脚本(e.x ./pjsip_auto2.6.sh)

#!/bin/sh

BASE_DIR=$(pwd)

# Create config_site.h file in path
echo "#define PJ_CONFIG_IPHONE 1 
#define PJ_HAS_IPV6 1
#include <pj/config_site_sample.h>" > pjlib/include/pj/config_site.h

echo 'Congratulation you have built PJSIP Library successfully'

Answer 3

由于PJSIP 2.5.5，libyuv包含在PJSIP包中，配置脚本param -with-libyuv被删除，请查看票证#1937以获得更多信息。
