Freeze runtime error

Hi,

I'm just trying out Freeze in my service and I'm getting the following error at runtime

09/29/09 14:43:08.793 CIceBoxServer2: error: ServiceManager: unable to load entry point `RngSvcI:create': /opt/ice/services/libRngSvcI.so: undefined symbol: _ZN11IceInternal6upCastEPN6Freeze10Connection.

Am I missing some shared libraries?

Thanks
Budyanto

Hi Budyanto,

You only need to link with Freeze library to use Freeze

If this not solve your issue, could you give us some more info? your compiler, Ice version , operating systems, and the command line use to link your service

Here's the info.

Compiler: gcc version 4.1.2 20080704
Ice version: 3.3.1-1
OS: CentOS 5
Command line used to link: g++ -shared -lFreeze objs/Rng.o objs/rng.o objs/RngI.o objs/RngSvcI.o -o dist/libRngSvcI.so

Thanks
Budyanto

Hi Budyanto,

You need to compile code with -fPIC see our demos as example of gcc options used to build the application

c++ -c -I. -I../../../include  -ftemplate-depth-128 -Wall -D_REENTRANT -I/usr/include/nptl -fPIC -g  HelloServiceI.cpp
rm -f libHelloService.so
c++ -shared -Wl,--enable-new-dtags -Wl,-rpath,/opt/Ice-3.4b/lib -rdynamic  -ftemplate-depth-128 -Wall -D_REENTRANT -I/usr/include/nptl -fPIC -g  -L../../../lib  -o libHelloService.so -Wl,-h,libHelloService.so   Hello.o HelloI.o HelloServiceI.o -lIceBox  -lIce -lIceUtil -lFreeze -lpthread -lrt

I have tested this with cpp/demo/IceBox/hello of the Ice distribution modified to create a Freeze env and connection on service start and it works

Hope this help,
José

That is it!

I had the -fPIC flag on the compile but not on the link. Thanks again.
