<div>
<pre>I have installed the latest version of XCode 4.6.2. Imagine there is a code
sample like below.
In one project I have 3 similar classes that use blocks. One is an Objective-C:
TestClass1.h:
@interface TestClass1 : NSObject
- (void)test;
@end
TestClass1.m:
@implementation TestClass1
- (void)test
{
void (^d_block)(void) =
^{
int n;
};
}
@end
One is in C++ (in the same project):
TestClass2.h:
class TestClass2
{
public:
void TestIt();
};
TestClass2.cpp:
void TestClass2::TestIt()
{
void (^d_block)(void) =
^{
int n;
};
}
One is in Objective-C++ (in the same project):
TestClass3.h:
class TestClass3
{
public:
void TestIt();
};
TestClass3.mm:
void TestClass3::TestIt()
{
void (^d_block)(void) =
^{
int n;
};
}
Clang compiles all these 3 classes successfully but blocks are the Objective-C
feature. It seems to me that the compiler should generate an error message in
.cpp file case. Is it a bug? Or maybe I don't understand something...</pre>
