Client as shared object

ramayanaramayana Member Stanislaw ArtymowskiOrganization: Instytut Monitorowania MediówProject: Testing and learning ICE
Hi,
i'm trying to make Client.cpp (even that from manual) as postgresql funtion. So i compiled (under Linux) Server like manual says and in Client i replace "int main(int argc, char* argv[])" to "::Ice::Double ClientSquare(::Ice::Double x)". I create Client.h:
#ifndef __Client_h__
#define __Client_h__
double ClientSquare(double x);
#endif

And i compiled this:
g++ -I. -I/home/include -fPIC -c -Wall Sqrt.cpp Client.cpp
g++ -shared -Wl,-soname,libsqrt.so.1 -o libsqrt.so.1.0.1 Sqrt.o Client.o -L/home/lib -lIce -lIceUtil

I don't know if i did that correct... Does anybody could tell me how to make client as shared object file?

Thanks for all suggestions

    Hi,

    I recommend checking out the compilation of the IceBox hello service for an example on how to build a shared library, the demo is located in your demo/IceBox/hello directory.

    Cheers,
    Benoit.

    Thanks for reply Benoit. But this example is for Windows and it shows how to make server as share library, and i would like make client as share object under linux. Does THIS example is also for me? I'm not very advanced in compiling under Linux.

    Hi,

    The IceBox hello demo also has a Makefile to build the demo on Linux. Building an Ice client or an Ice server as a shared library is the same so I recommend checking out the build commands of this demo to figure out how to build your Ice program as a shared library on Linux.

    If you are looking for instructions on how to write an Ice client (and not only how to build it), you should start with taking a look at demo/Ice/minimal/Client.cpp (and not the IceBox hello code which is not what you want). This minimal client demonstrates the code required at a minimum to make an Ice invocation on a server.

    Cheers,
    Benoit.

    Meybe i don't understanding something but in folder ZeroC\Ice-3.4.2-demos\demo\IceBox\hello i have only Makefile.mak, which is for Windows, but i can't find makefile for Linux.

    For Unix platforms, you need to download the sample programs archive from our download page at this link.

    Note that if you are trying to build a postgresql function, your ClientSquare function must use extern C linkage, see PostgreSQL documentation about using C++ PostgreSQL: Documentation: 9.1: C-Language Functions

    So of course you're right :) But now when i do make in ~/Ice-3.4.2-demos/demo/ $ or ~/Ice-3.4.2-demos/demo/IceBox $
    i always get error:
    make[2]: *** No rule to make target `/usr/lib/libSlice.so.3.4.2', needed by `Hello.cpp'.  Stop.
    

    I working under Gentoo and i get Ice from emerge Ice, so i have installed

    * dev-libs/Ice
    Latest version available: 3.4.1
    Latest version installed: 3.4.1
    Size of files: 5,140 kB
    Homepage: Welcome to ZeroC, the Home of Ice
    Description: ICE middleware C++ library and generator tools

    but i also see

    * dev-cpp/IceE [ Masked ]
    Latest version available: 1.3.0-r1
    Latest version installed: [ Not Installed ]
    Size of files: 1,222 kB
    Homepage: ZeroC - Ice-E Overview

    Should i install dev-cpp/IceE? I've read that that error shows when you don't have installed Ice, but i have dev-libs/Ice
    dev-cpp/IceE

    The demo fails to build because you have not installed Ice-3.4.2. If you are using 3.4.1 you can download 3.4.1 demos from http://www.zeroc.com/download/Ice/3.4/Ice-3.4.1-demos.tar.gz

    You can also try to update to Ice-3.4.2, build it from source , or unmask the Ice-3.4.2 package in gentoo portage.

    To install 3.4.2 from gentoo portage.
    # echo "=dev-libs/Ice-3.4.2 **" >>  /etc/portage/package.keywords 
    # emerge dev-libs/Ice -a
    These are the packages that would be merged, in order:
    
    Calculating dependencies... done!
    [ebuild  N    ~] dev-libs/Ice-3.4.2  USE="ncurses -debug -doc -examples -mono -python -ruby -test" RUBY_TARGETS="-ruby18" 
    
    Would you like to merge these packages? [Yes/No]

    I have made that using classic hello world from IceManual for C++. I had to manual compile library with postgreSQL and it's working!

    Thanks for your help!
