我在/ etc/inittab中运行带有条目的BusyBox

::sysinit:/etc/init.d/rcS

rcS脚本在启动时调用/etc/rc.d/中的所有启动脚本.

如何通过调用/etc/rc.d/xxx停止调用BusyBox小程序"poweroff","halt"或"rebo​​ot"来告诉BusyBox init关闭所有服务？

我正在编写CMake 2.8.11.2,CPack和NSIS的安装程序.我来到了需要调用像MSVCR这样的子安装程序的地步.这是我的CMakeLists.txt的样子:

set(CPACK_GENERATOR NSIS)
list ( APPEND CPACK_NSIS_EXTRA_INSTALL_COMMANDS " ExecWait ./tmp/vcredist_x64.exe")
list ( APPEND CPACK_NSIS_EXTRA_INSTALL_COMMANDS " ExecWait ./tmp/some-other-installer.exe")
list ( APPEND CPACK_NSIS_EXTRA_INSTALL_COMMANDS " RMDir /r ./tmp/")
INCLUDE(CPack)

但是,生成的.nsi文件包含以下(单个)行

ExecWait ./tmp/vcredist_x64.exe; ExecWait ./tmp/some-other-installer.exe; RMDir /r ./tmp/

这会导致错误"ExecWait需要1-2个参数,得到6",同时生成包.

如何正确地将多个额外命令传递给NSIS？

With boost signals (which is now deprecated) I always wrapped connection management and signal invocation with a mutex in order to be thread-safe. Boost signals 2 should give that out-of-the-box. But:

According to the Boost Signals2 Thread-Safety documentation, it is possible to disconnect slots from thread A while they are executing on thread B. Let's assume I created an object O on thread A and connected a member function of O to a signal S that is executed on worker …
