在编译WebRTC的汇编文件时遇到错误，特别是在iOS平台和armv7架构下。解决方案是将构建配置中的'OS=ios target_arch=armv7'改为'target_arch=arm arm_version=7'。修改后，重新执行编译步骤，问题即可得到解决。

webrtc 编译汇编文件时错误

@ This file was created from a .asm file

解决办法：
把OS=ios target_arch=armv7 改为target_arch=arm arm_version=7
即把

export GYP_DEFINES="OS=ios target_arch=armv7”

改为：

export GYP_DEFINES="OS=ios target_arch=arm arm_version=7"

然后重新执行

webrtc/build/gyp_webrtc，

最后重新编译。

错误日志类似下面的：
