Help: Install WOW

I try to install WOW (World Oracle Web) under Unix-sco with Oracle7 Server Release 7.1.5.2
when compiling the kit, i have the error message  undefined symbol ( many symbols ...) in file $ORACLE_HOME/lib/libsqlnet.a

I have find this explication in the online documentations help, but i don't understand it very well ,
can anybody explain me this ?

 Q: I get undefined symbols when linking WOW!

1. Your are not using Oracle 7.1.3! Either upgrade, or link WOW using the same libraries as the demos in $ORACLE_HOME/rdbms/lib/oracle.mk

Thanks
Haithem
