Freeze does not compile for me in Ice 2.1.0

aclysma

I'm pretty sure this is NOT a 2.1.0 bug because I had the same problem before. I was kind of hoping the problem would go away with 2.1.0.

Anyways, my build freezes when it hits freeze. How ironic. I've looked around on the forum and it seems that not having the right kind of berkley db installed would do this.

I am using 4.2.52-90, and I imagine suse does the compile option for c++ because the suse 9.2 built in rpm "provides" libdb-4.2.so and libdb_cxx-4.2.so

Please keep in mind I'm pretty new to linux, so don't rule anything out that should be obvious! I probably havn't done it.

I'll post an excerpt of my build. For grins, I also tried it as root.

IC -Wall -D_REENTRANT ConnectionF.cpp

I'm using a fairly "normal" suse 9.2 pro, with gcc-v

philipd@linux:~> gcc -v

Whatever I need to do or whatever information is needed, I'll be more than happy to oblige.

Hi,

My guess is that you don't have the berkeley db 4.2.52 development RPM (db-devel 4.2.52) installed since the compilation is not finding db_cxx.h. Try installing this http://www.novell.com/products/linuxpackages/professional/db-devel.html RPM and let us know if this solves your problem.

Regards, Matthew

Depending on your distribution, your db-devel or db4-devel will or will not include the libdb_cxx.so symbolic link.

It should be included, but it's unfortunately not obvious to everybody:
https://bugzilla.redhat.com/beta/show_bug.cgi?id=149191

If you don't have this symbolic link, I recommend to create it yourself (as root); alternatively you can edit Ice's config/Make.rules and replace -ldb_cxx with -ldb_cxx-4.2.

Cheers,
Bernard

gcc 3.3

Excelent advice. Installing the development package fixed it for me. Like I said... something simple

But now I have another problem.

philipd@linux:~/build/Ice-2.1.0/bin> ./slice2cpp
./slice2cpp: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

I think this is caused by using gcc 3. Is there something I need to do to make it work with libstdc++.so.5?

Thanks
Philip

mysteriously is working

Well, I somehow mysteriously got it working. It isn't working under root but it is working under my username, philipd. I'm not sure why and if someone knows offhand, I'd appreciate the education But regardless, it works, and now I get to play with Ice.

By the way, thanks for putting out such a great product and lending a hand so readily. This is such a great community.

Thanks
Philip

I'm glad you got it work . I must say I was a bit puzzled by the error! I don't quite understand why it's looking for libstdc++.so.6 if you only have libstdc++.so.5 installed. It sounds like the root user and your regular user have different environments... The best way to track this down is to compare the LD_LIBRARY_PATH environment variable under both accounts. You can also use the ldd command to see against which library slice2cpp is linked and how the libraries are resolved in the current environment:

$ ldd ./slice2cpp

You should try this under both accounts and see the differences.

Hope this helps!

Benoit.
