Problem with Hello World?

ddunn

I can't get slice2cpp to run on Printer.ice, nor can I get it to correctly compile when I use already generated versions of Printer.h & Printer.cpp. The former complains of missing libSlice.so.31, and the latter gives a spray of 'undefined' errors for ice components. I suspect the installation may not have worked properly, but I don't know how to fix it. What should I do? (What info do I need to provide?)

OS: Centos 4.4 (supposedly exactly compatible with RedHat 4.4)

marc

What are the error messages exactly? For the first problem, it appears that libSlice.so.31 cannot be found in your LD_LIBRARY_PATH. For the other problem, I need the exact error message to provide further assistance, as well as the exact command you use to compile and link the application.

ddunn

For the first problem, how would I check/correct that?

For the second:

Okay, I type in the command:

c++  ice_server.cpp -I/Ice-3.1.0/include -I./

And I get:

For the first problem, simply add /Ice-3.1.0/lib to your LD_LIBRARY_PATH environment variable. For example:

$ LD_LIBRARY_PATH=/Ice-3.1.0/lib:$LD_LIBRARY_PATH
$ export LD_LIBRARY_PATH

Note that this doesn't have anything to do with Ice in particular, this is simply standard Linux/Unix system administration.

For the second problem, you must link with the proper Ice libraries, i.e., add -lIce -lIceUtil to your command line. Also add -L/Ice-3.1.0/lib, so that the libraries can be found. Again, this is standard C/C++ development procedure for Linux/Unix, and not specific to Ice.

ddunn

Right, but I don't know all the standard Linux/Unix stuff. So, please bear with me if I make a rather stupid mistake, okay?

marc

I forgot to mention that you must of course also link with the Printer.o file. In general, it is advisable to split compilation and linking:

c++ -c ice_server.cpp -I/Ice-3.1.0/include -I./
c++ -o ice_server ice_server.o Printer.o -L/Ice-3.1.0/lib -lIce -lIceUtil

For more information, please refer to the GNU C++ compiler documentation.

ddunn

That cleared most everything up, except for one thing. I type in:

$ ./ice_server

And then it complains about the shared libraries:

./ice_server: error while loading shared libraries: libIce.so.31: cannot open shared object file: No such file or directory

This clearly isn't the case, as I checked the directory. But I can't seem to make the program realize that. I've tried appending the /lib and /bin directories to the PATH variable, and tried copying the libraries to the same directory as my program, but no avail. It's got to be something small that I'm missing, but I don't know what...

dwayne

It would appear that you do not have your LD_LIBRARY_PATH environment variable set correctly. It needs to include the lib directory of your Ice installation.

ddunn

I don't think that's it, because I added it.

(Terminal excerpt:)

TRICK: echo $LD_LIBRARY_PATH
/Ice-3.1.0/lib
TRICK:

(The prompt is changed, but I'm using bash)

Is that what it's supposed to look like, or did I miss something?

ddunn

Nevermind, I think I found it. Looks like I missed the 'export' command in the shell script.
