Can anybody tell me if this is because “Protocol” is a reserved word
in
Objective C?
If so, can anyone think of a work=-around? The only idea I have is

back and forth.
Thanks all.
Protocol is not a reserved word, it is a type defined in objc/
runtime.h
#ifdef __OBJC__
@class Protocol;
#else
typedef struct objc_object Protocol;
#endif
A workaround may be to use a macro to hide the objc variable (untested).
#define Protocol ObjCProtocol
#import Cocoa/Cocoa.h
#undef Protocol
An other workaround is to wrap your oracle calls into a .cpp file that
includes occiAQ.h, and then call thoses functions from you objcpp
file.
--- mywrapper.h
extern
int myOracleFunction();
--- mywrapper.c --
#include mywrapper.h
#include occiAQ.h
int myOracleFunction() {
// perform oracle specific code
}

Re: Oracle and Objective C++
Also file a bug report with Oracle: describe the issue and suggest to them that if they're using C++, they ought to use namespaces in order to avoid naming conflicts. -- Scott Ribe [EMAIL PROTECTED] http://www.killerbytes.com/ (303) 722-0567 voice ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Oracle and Objective C++
I'm having difficulty importing data from an Oracle database into a
Cocoa application.
I've installed the Oracle client and OCCI examples. The example
occidml.cpp seemed to make and run just fine from the command line.
Now, I would like to get some data from Oracle into my Cocoa application
but I'm stuck. Since the Oracle header files are for C++ programs I thought
an objective C++ solution would be the easiest.
With obvious credit due to Oracle engineers, my header file starts off
like:
#import Cocoa/Cocoa.h
#include iostream
#include occi.h
using namespace oracle::occi;
using namespace std;
class occiCon {
private:
Environment *env;
Connection *conn;
Statement *stmt;
public:
occiCon (string user, string passwd, string db){
env = Environment::createEnvironment (Environment::DEFAULT);
conn = env-createConnection (user, passwd, db);
}
~occiCon () {
env-terminateConnection (conn);
Environment::terminateEnvironment (env);
}
But I get the following errors when I try to compile it.
Line Location occiAQ.h:280: error:
'oracle::occi::aq::Subscription::Protocol' has a previous declaration here
Line Location occiAQ.h:280: error:
'oracle::occi::aq::Subscription::Protocol' has a previous declaration here
Line Location occiAQ.h:320: error:
'oracle::occi::aq::Subscription::Protocol' referred to as 'struct'
Line Location occiAQ.h:321: error:
'oracle::occi::aq::Subscription::Protocol' referred to as 'struct'
Looking at Oracle's header file: occiAQ.h in the area of line 280:
