Objective C and gcc problems

I have just been following the tutorial in the "Learning Cocoa" book and had problems with the follow code:

int main (int argc, const char * argv[])
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSMutableArray *myArray = [[NSMutableArray alloc] init];

[myArray addObject: @"Here's a string"];

int itemCount;
itemCount = [myArray count];

NSString * myString;
myString = [myArray objectAtIndex: 0];

[myArray insertObject: @"Hello2" atIndex: 0];

[myArray exchangeObjectAtIndex: 0 withObjectAtIndex: 1];

// insert code here...
NSLog(@"Hello, World!");
NSLog(@"Array description: %@ items.\n", myArray);

[myArray release];
[pool release];

return 0;
}


which gives me the following result:



main.m:10: illegal expression, found `int'
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
main.m: In function `main':
main.m:10: parse error before `int'
main.m:11: `itemCount' undeclared (first use in this function)
main.m:11: (Each undeclared identifier is reported only once
main.m:11: for each function it appears in.)
main.m:13: parse error before `*'
main.m:14: `myString' undeclared (first use in this function)


the gcc version as provided by "cc -v" is: "Apple Computer, Inc. version gcc-926, based on gcc version 2.95.2 19991024 (release)".

Who is right, the book or the compiler?

Andre
