我一直在尝试为 arm64 架构构建 Libyuv，然后将其集成到 PJSIP 库中。但是我没有取得任何进展，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

这是所在的文件夹libyuv.a。

但是，在配置时，会出现此行：

checking for I420Scale in -lyuv... no

关于这里有什么问题的任何建议？

参考 ：

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

  2. 构建 libyuv：https ://trac.pjsip.org/repos/ticket/1776

更新

这就是我构建的方式libyuv.a

  1. GYP_DEFINES="OS=ios target_arch=arm64 target_subarch=arm64" GYP_CROSSCOMPILE=1 GYP_GENERATOR_FLAGS="output_dir=out_ios" ./gyp_libyuv -f ninja --depth=. libyuv_test.gyp

  2. ninja -j7 -C out_ios/Release-iphoneos libyuv_unittest

这成功地创建了库，但我没有得到连接该库的正确方法！

事实证明，如果您使用 PJSIP 的最新版本并libyuv按照问题中的描述安装框架，它就会完美地构建。

只需使用以下命令查看修订版 5128：

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

它还包含 iOS 中的方向修复！

从 PJSIP 2.5.5 开始，libyuv 包含在 PJSIP 包中，并且删除了配置脚本参数 --with-libyuv，请查看票证 #1937 了解更多信息。

使用以下脚本构建 PJSIP 库。

脚步 ：

  1. 复制脚本并制作 .sh 文件。
  2. 将 .sh 文件复制到 PJSIP Lib 文件夹中。
  3. 运行 chmod 777 .sh_filename
  4. 运行脚本（例如 ./pjsip_auto_2.6.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
