/usr/hydra/hydra.lnx/ ./hstudio/qxdev2: error while loading shared libraries: libstdc++-lib6.2-2.so.3: cannot open shared object file : No such file or directory

this is due to missing operating system packages.

The following RPM packages must be installed to run 'Hydra4GL':

glibc-kernheaders-<version>
compat-libstdc++-6.2-<version>

Fedora Core 3/4

Users working with Red Hat Fedora Core 3/4 may encounter errors of the form:

Error opening DB driver: /usr/querix/./lib/moddbdefault.so
/usr/querix/./lib/moddbdefault.so: cannot restore segment prot after reloc: Permission denied

This is caused by the SELinux system blocking the use of shared objects. You are able to fix this with:

chcon -t texrel_shlib_t $QUERIXDIR/lib/*.so*

If this does not work, try disabling SELinux altogether by setting the line

SELINUX=disabled

in your /etc/sysconfig/selinux file.
