Is your program SUID root? You can't use LD_LIBRARY_PATH with SUID root programs (because that would allow you to interpolate your own library into a highly privileged program, with goodness only knows what consequences (but they are unlikely to be good. Consider using -R/usr/informix/lib/esql at link time and/or LD_RUN_PATH=$LD_LIBRARY_PATH:... at runtime. I think that LD_RUN_PATH may still be ineffective for SUID root programs. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2003.04 -- http://dbi.perl.org/
