1.3.1 Ubuntu 18.04 WSL missing so

[philshafer]

Is the library (libxo.so.0) installed in /usr/local/lib? What does "ldd /usr/local/bin/xo" report? Also "ldconfig -r" may be helpful.

Thanks,
Phil

If I had to guess, I would think perhaps one of these asterisks is at fault here. Let me know if I can provide anything else to assist here.

The asterisk is “ls”s’ way of telling you the file is marked executable.

ll /usr/local/lib/ lrwxrwxrwx 1 root root 14 Nov 16 22:36 libxo.so -> libxo.so.0.0.0* lrwxrwxrwx 1 root root 14 Nov 16 22:36 libxo.so.0 -> libxo.so.0.0.0* -rwxr-xr-x 1 root root 462112 Nov 16 22:36 libxo.so.0.0.0*

This means that the library definitely is installed correctly. Good news!

ldd /usr/local/bin/xo linux-vdso.so.1 (0x00007fffe054f000) libxo.so.0 => not found libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f47b2310000) /lib64/ld-linux-x86-64.so.2 (0x00007f47b2a00000)

This means that the loader is not finding libxo, which I’d assume means that it’s not looking in /usr/local/lib for libraries.

ldconfig -r /sbin/ldconfig.real: option requires an argument -- ‘r'

That’s interesting. The “-r” option has a different meaning that under FreeBSD, where it means: -r List the current contents of the hints file on the standard output. The hints file is not modified. The list of directories stored in the hints file is included. Under linux, it means: -r root Change to and use root as the root directory. So much for compatibility, eh? So instead try “ldconfig -p”, which means: -p, --print-cache Print the lists of directories and candidate libraries stored in the current cache. Could you also run “ls /opt/local/lib/“ and see if that’s the preferred location for your linux distro? If you see a nice selection of libraries in that directory, then you should: - Remove the current libxo install using make uninstall - reconfigure with the prefix “/opt/local” ../configure --prefix /opt/local - rebuild make clean && make && make test && make install Then rerun your “ldd /opt/local/bin/xo” and see if you’ve succeeded. Thanks, Phil
