oratcl

I am getting this when I try to build on my Mac:

gcc -dynamiclib -pipe  -Os -Wall -Wno-implicit-int -fno-common   -prebind -headerpad_max_install_names -Wl,-search_paths_first  -Wl,-single_module -o libOratcl4.5.dylib oratcl.o oralob.o oralong.o oralogon.o oralogoff.o oraopen.o oraclose.o oracommit.o oraroll.o oraautocom.o orainfo.o oramsg.o oraconfig.o oradesc.o orabreak.o oraparse.o orabind.o oraexec.o orafetch.o orasql.o oraplexec.o orabindexec.o  -L/System/Library/Frameworks/Tcl.framework/Versions/8.4 -ltclstub8.4 
ld: duplicate symbol _OCI_EnvCreate in oralong.o and oratcl.o
collect2: ld returned 1 exit status
make: *** [libOratcl4.5.dylib] Error 1

The INSTALL file says for building on the Mac to refer to the "mac" directory, which doesn't exist. Anyone have any ideas?

Ok, so I got the compile to go by:

First, adding "extern" to all OCIs in generic/oratclTypes.h, for example:

extern OCIENVCREATE     OCI_EnvCreate;

Second, creating a new file and including it in the build, the contents of which are:

#include "oratclInt.h"
#include "oratclTypes.h"

OCIENVCREATE    OCI_EnvCreate;
...

and so forth for each OCI that is found in generic/oratclTypes.h.
