关于ServiceConfigurator的使用问题

okibun0129

对于ACE目录下的$(ACE_ROOT)ACE_wrappers\examples\Service_Configurator\IPC-tests\server的服务器的例子。
配置文件为svc.conf，使用其中的动态服务
dynamic Remote_Brdcast Service_Object * ./IPC_Tests_Server:remote_broadcast "-p 10001"
然后提示动态链接库IPC_Tests_Server.dll无法打开，因此动态服务无法被加载。
首先我确保被调用的DLL与exe文件在同一目录下，麻烦老大帮分析一下，下面附堆栈信息与日志输出信息。
函数调用的堆栈信息：DLL文件是成功打开了，但是最终调用包装的系统函数ACE_OS::dlopen确失败了。
最终返回的handle为0._errno 返回 0x00a91ec8 int *，lookup找不到相关错误描述信息。

单步跟踪一下比较理想。DLL load成功，决定因素有好几个呢。比如是否有依赖的DLL文件，dllmain中是否有什么操作等。
