OpenVox 驱动

• 源码下载
  • www.openvox.cn/pub/drivers/dahdi-linux-complete/releases
  • 2.11.1 官方的有一点问题, 可以尝试使用 wenerme/openvox-dahdi-linux 的 myfix 分支
• NOTE
  • hardened 的内核编译会失败, 并且在编译过程中会报很多异常
    • can't find starting instruction / can't decode instruction
      • stack-validation.txt
  • DAHDi 的 hardened 编译也加了不少补丁
    • git.alpinelinux.org/cgit/aports/tree/main/dahdi-linux-hardened
  • vaillian 的内核能直接编译成功

wget http://www.openvox.cn/pub/drivers/dahdi-linux-complete/openvox_dahdi-linux-complete-current.tar.gz
tar zxvf openvox_dahdi-linux-complete-current.tar.gz
cd dahdi-linux-complete*

apk add bison zlib{,-dev} ncurses{,-dev} libxml2{,-dev} openssl{,-dev} gnutls{,-dev} linux-headers make abuild gcc g++ perl git wget

# 要看具体使用的什么内核 uname -r
# apk add linux-hardened{,-dev}
apk add linux-vanilla{,-dev}

# 或者用 docker 编译
docker run -it --rm -v $PWD:/src wener/asterisk:builder bash

# 先编译 dahdi 驱动
make install -C linux KVERS=4.9.49 DESTDIR=$PWD/dist/4.9.49

# 如果是 hardened 那么一般是这样的
make install KVERS=4.9.32-0-hardened
# 安装到其他地方
make install KVERS=4.9.32-0-hardened DESTDIR=$PWD/dist/4.9.32-0-hardened
