IDS/LE & ODBC Problem

Hello, I tried to use the odbc driver ivinf913.so but I just could not connect to the database. I have used the ivtestlib provided by the informix linux odbc driver. Here's the output : ------------------------------------------------------ $ ivtestlib /usr/lib/ivinf913.so /lib/libNoVersion.so.1 => /lib/libNoVersion.so.1 (0x4004e000) libpthread.so.0 => /lib/libpthread.so.0 (0x40056000) libivmfront.so => /usr/lib/libivmfront.so (0x40067000) libivbas13.so => /usr/lib/libivbas13.so (0x40070000) libivutl13.so => /usr/lib/libivutl13.so (0x40121000) libthsql.so => not found libthgen.so => not found libthos.so => not found libthasf.so => not found libifgls.so => not found libifglx.so => not found libstdc++.so.2.8 => /usr/lib/libstdc++.so.2.8 (0x401d7000) libm.so.6 => /lib/libm.so.6 (0x40218000) libc.so.6 => /lib/libc.so.6 (0x40234000) libdl.so.2 => /lib/libdl.so.2 (0x40322000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000) ------------------------------------------------------ Why was some of the library files not found ? Am I doing something not right ? Platform is linux (RH 5.2) and IDS-7.30.UC5-1. Thanks for any advice. :) Regards, Keith.
