vc服务程序带有opencv相关代码就启动不了。

[wuxiao0313]

windows10下，vc编写的服务程序，只要程序中包含opencv相关的代码服务就不能启动，将其全部注释掉就可正常启动。 有遇到类似情况的吗？

可能是opencv有用到用户session的东西，而服务session没有桌面等

服务设置了与桌面交互，但你说这个我想到了系统权限和令牌的一些问题，我加进去试试

用调试器(OD,WINDBG等)调试服务程序
To debug the initialization code of a service application, the debugger must be attached when the service is started. This is accomplished by creating a registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ProgramName


The ProgramName is the image file for the service application you are debugging. Do not specify a path. For example, the ProgramName might look like MyService.exe.

Under this key create a string data value called Debugger. The value of this string should be set to the full path of the debugger that will be used. For example,

c:\Debuggers\windbg.exe



In addition to setting this registry key, the service application must be marked as "interactive". This allows your service to interact with the desktop, and allows the debugger window to appear on your desktop.

This again requires modifying a registry key: you must bitwise-or the type entry for your service with 0x100 (this is the value for SERVICE_INTERACTIVE_PROCESS according to Winnt.h). The exact location and name of this registry entry varies. For example:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MyServiceKey


Finally, you need to adjust the service application timeout. Otherwise, the service application will kill the debugger within 20 seconds after starting. Adjusting the timeout involves setting an entry in the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control


Under this key, create a DWORD data value called ServicesPipeTimeout. Set this entry to the amount of time in milliseconds that you want the service to wait before timing out. For example, 60,000 is one minute, while 86,400,000 is 24 hours.

设置ServicesPipeTimeout后需要重启系统才生效

Now, when the service is started, the debugger will also start. When the debugger starts, it will stop at the initial process breakpoint, before the service has begun running. This allows you to set breakpoints or otherwise configure your debugging session to let you monitor the startup of your service. Another option is to place calls to the DebugBreak function in your service from the point at which you would like to break into the debugger. (For more information, see DebugBreak in the Platform SDK documentation.)

If your service is running with other services in a Service Host Process, you may need to isolate the service into its own Service Host Process.

库文件路径之类的对吗？是不是缺库文件

[jacksonfan]

怀疑是dll相关库路径的问题

[shiter]

这种问题一定是没配置正确
