Shared library error on start

The most likely cause is that one or more shared libraries are not installed. Ensure that all prerequisite libraries are installed. First, use the “ldd” command to show what libraries HAAst needs, and are available:

root@pbx~$ldd haast
linux-vdso.so.1 => (0x00007ffffbded000)
libQt5Sql.so.5 => not found
libQt5Xml.so.5 => not found
libQt5Network.so.5 => not found
libQt5Core.so.5 => not found
libpthread.so.0 => /lib/x86_64-linuxgnu/
libpthread.so.0 (0x00007ff6b71c4000)
libstdc++.so.6 => /usr/lib/x86_64-linuxgnu/
libstdc++.so.6 (0x00007ff6b6ec3000)
libgcc_s.so.1 => /lib/x86_64-linuxgnu/
libgcc_s.so.1 (0x00007ff6b6cad000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff6b68ed000)
/lib64/ld-linux-x86-64.so.2 (0x00007ff6b73ef000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007ff6b65f0000)

You would then have to add the missing libraries (normally through your package manager like apt-get or yum). In the above example case, the Qt libraries are missing; see section 7 of the instructions for details on how to add the Qt libraries to your Linux distribution.
