We are trying to deploy RCF server on Linux but getting error while execute "make" command.
OS: OEL 7.3
Protoc version: 2.4.1
Purpose to make source code is to create .so files for linux system.
Ref. url: http://www.deltavsoft.com/RCFProto/dist ... /java.html

We have followed steps given for Ubuntu (Linux) and find below error:
---------------------------------------------------------------------------------------
[root@hostname make]# cmake -G "Unix Makefiles" ..

Please help to get it make successfully.
Or please share libRCFProto_Java_impl.so and RCFProto.jar for same protoc version and OS.
Or please share steps to deploy on OEL 7.3.

Thank you in advance!

I'm not sure what's going on there. Can you verify that you have the relevant RTTI compiler flags turned on for all the binaries you are building?

If worst comes to worst, you can try commenting out the code that is causing the linker error, in RcfServer.cpp:

Code: Select all

            if (taskEntry.mMuxerType == Mt_None && !taskEntry.mLocalThreadPoolPtr)
            {
                taskEntry.mLocalThreadPoolPtr.reset( new ThreadPool(1) );

                //if ( mThreadPoolPtr && boost::dynamic_pointer_cast<UdpServerTransport>(servicePtr) )
                //{
                //    for ( std::size_t i = 0; i < mThreadPoolPtr->mThreadInitFunctors.size(); ++i )
                //    {
                //        taskEntry.mLocalThreadPoolPtr->addThreadInitFunctor(mThreadPoolPtr->mThreadInitFunctors[i]);
                //    }
                //    for ( std::size_t i = 0; i < mThreadPoolPtr->mThreadDeinitFunctors.size(); ++i )
                //    {
                //        taskEntry.mLocalThreadPoolPtr->addThreadDeinitFunctor(mThreadPoolPtr->mThreadDeinitFunctors[i]);
                //    }
                //}
            }
