How to link Linux C++ Ice
Hello,
As far as I know, I've successfully built the Ice in my Linux environment, I want to verify the same thing I did earlier this week in Windows C# .NET, except this time in C++ Linux environment, because that's what we'll be running in development more frequently into production.
However, I am receiving many linker errors undefined references to Ice::Application::main(int, char**, char const*).
This tells me that somehow I am not linking correctly against the SO's, libIce.so, libIceUtil.so, and so on. Or possibly I need to rebuild Ice with correct SO output for our build environment.
From what I know about our build system as well, the default tendency is to prefer dynamic linkage I think. I'll rebuild from Ice source if I need to obviously.

Unless possibly it is build correctly in and of itself, but is a binary incompatible issue making its way into our build system.0

Hi,
You can look at Ice c++ demos for examples. Basically you need to link with Ice and IceUtil dynamic libraries, the link command will look something like:c++ -Wl,--enable-new-dtags -Wl,-rpath,/opt/Ice-3.4/lib -rdynamic -Wall -D_REENTRANT -fPIC \ -g -L/opt/Ice-3.4/lib -o server Hello.o HelloI.o Server.o -lIce -lIceUtil -lpthread -lrt
