[pdp-discuss] oldlba, 3.1 and libraries

[allan.randall at ntt.ca]

Hi,

I have been running 3.2a07 (leabra++) and doing pretty well with it. However, occasionally, I have to run one of the demos from the "Explorations" book, so I use oldlba++, which is the version with the out-dated stuff to make the demos not break. The only problem is that I have found that the demos still break or have problems occasionally, so oldlba++ is not foolproof.

So I decided that it would be nice to have a working 3.1 around to run leabra++ when I want to show demos, without fear of compatibility problems. The demos ran fine under 3.1 (installed binaries) on my old Fedora 2 Linux machine, but I have since upgraded to a new Fedora 5 system, and I get missing library errors. 

Installing from RPM
   rpm -Uvh pdp++-binext-3.1-0.i386.rpm

gets me:

error: Failed dependencies:
        libreadline.so.4 is needed by pdp++-binext-3.1-0.i386
        libstdc++-libc6.2-2.so.3 is needed by pdp++-binext-3.1-0.i386
        libstdc++-libc6.1-1.so.2 is needed by pdp++-binext-3.1-0.i386

If I try to install the binaries from the tar file (no rpm), I get missing file errors for the same libraries.

Perhaps the 3.1 binaries are just incompatible with Fedora 5, and I need to stick with oldlba? I don't think I need to build 3.1 from source, but maybe that is what I need to do?

Anyone know the answer? And/or a way to decrease risk of failure when running demos in oldlba++?

Cheers,
