Hi all,

Since Oracle released no patch for its HTTP server for v 8.1.7 (based on Apache), i'm trying to fix this by myslef. I took Apache 2.0.39 and mod_owa, which is an open-source alternative for Oracle's mod pl/sql and trying to compile this module to have Apache server, that communicates with Oracle. What i'm getting are some unresolved symbols, while compiling mod_owa.

My questions are:

Has anyone successfully compiled this module ?

Is there any other way to solve recent Apache vulnerability ?

DS10, 4.0F, Oracle 8.1.7

# make -kf modowa.mk
cc -shared -o mod_owa.so owautil.o owafile.o owanls.o owasql.o owadoc.o owahand.o owaplsql.o owacache.o modowa.o -L/data3/oracle/app/oracle/product/8.1.7/lib -lpthread -lclntsh -L/usr/lib -lc

 I edited modowa.mk for linux, i had to remove -ldl from $CLIBS, because i don't have any libdl.* and i'm not sure if those unresolved symbols are related to this library. ORACLE_HOME is set correctly.

now it looks like this:

************************************

#
# Makefile for mod_owa.so
#
.SUFFIXES:
.SUFFIXES: .lc .oc .lpc .opc .pc .c .o .cpp .oln

ORA_LIB = $(ORACLE_HOME)/lib

CC = cc

CFLAGS = -DAPACHE20 -DUNIX -EAPI -O
LDFLAGS = -shared

CLIBS = -L/usr/lib -lc

ORALINK = -L$(ORACLE_HOME)/lib -lpthread -lclntsh

OBJS = owautil.o owafile.o owanls.o owasql.o \
                  owadoc.o owahand.o owaplsql.o owacache.o modowa.o

mod_owa.so: $(OBJS)
        $(LD) $(LDFLAGS) -o $@ $(OBJS) $(ORALINK) $(CLIBS)

.c.o:
        $(CC) $(CFLAGS) $(INCLUDES) -c $<

*****************************

Thanks in advance for your help
