LIRC在重新启动后不会启动。

Question

如果我用this patched lirc编译LIRC，然后使用make install进行安装，它运行良好，启动时没有任何错误。但是，在重新启动后，相同的命令会出现以下错误：

root@NAS:~# lircd --device=/dev/ttyACM0 --driver=usb_irtoy
lircd: can't open or create /var/run/lirc/lircd.pid
lircd: No such file or directory
root@NAS:~#

有什么可以解释的吗？

好吧，我找到解决办法了。我们需要在每次引导时手动创建/var/run/lirc/目录。我编辑了lirc init.d脚本，如下所示，它使用代码[ -d "/var/run/lirc" ] || mkdir -p "/var/run/lirc"创建目录。

#! /bin/sh
#
# This is an init script for Debian 2.1 Slink distribution.
# Copy it to /etc/init.d/lirc and type
# > update-rc.d lirc defaults 20
#


test -f /usr/local/sbin/lircd || exit 0
test -f /usr/local/sbin/lircmd || exit 0

case "$1" in
  start)
    [ -d "/var/run/lirc" ] || mkdir -p "/var/run/lirc"
    echo -n "Starting lirc daemon: lircd"
