* Jeremy Dawson:

Trying to run polyml I get the following error:

[jeremy@home2006 ~]$ poly poly: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

It seems that binary was compiled with the wrong GCC version. This is odd, because the RPM says "3.fc12", which is fairly recent.

What does "type -a poly" show?

This is in Fedora 13 running the package

[jeremy@home2006 ~]$ rpm -q -i polyml Name : polyml Relocations: (not relocatable) Version : 5.2.1 Vendor: Fedora Project Release : 3.fc12 Build Date: Tue 28 Jul 2009 02:18:46 PM EST

From the release, I assume you are trying to run a Fedora 12 package on

Fedora 13. In general recompiling the source RPM is more likely to work.

But the package allegedly requires libstdc++.so.6

[jeremy@home2006 ~]$ rpm -q -R polyml libc.so.6 libc.so.6(GLIBC_2.0) libdl.so.2 libgcc_s.so.1 libm.so.6 libpolyml.so.1 libpthread.so.0 libstdc++.so.6 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rtld(GNU_HASH) rpmlib(PayloadIsXz) <= 5.2-1

and that file is there

[jeremy@home2006 ~]$ ls -l /usr/lib/libstdc++* lrwxrwxrwx. 1 root root 19 May 13 11:19 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.13 -rwxr-xr-x. 1 root root 942040 May 4 07:14 /usr/lib/libstdc++.so.6.0.13

Is this a problem with polyml or with Fedora ?

It seems to me to be a problem with the dependencies of that package, as it should have prevented installation on a Fedora 13. Maybe the spec-file can give a hint of what is wrong, but most often these dependencies are determined automatically. An ldd on each library and executables from the package may reveal the origin of the libstdc++.so.6 dependency.
