You should add Informix libraries - at least -L$INFORMIXDIR/lib -L$INFORMIXDIR/lib/esql \\ -lixsql -lixasf -lixgen -lixos -lixgls -lnsl -lsocket -laio -lm 2. Another way is to run esql -v somefile.ec and look into "ld" command line parameters 3. Simplest method: esql -o prog smain.c -L./ -lfunc Hope this helps Leonid
