我正在使用Objective C++編寫框架，並且在設置單元測試時遇到了問題。用Xcode 4.x進行單元測試Objective-C++框架
僅編譯框架目標就可以正常工作。
但是，當我告訴Xcode的編譯和運行測試包，我得到：

我：
C++ Language Dialect: c++11
C++ Standard Library: libc++
上都構建目標（框架&測試包）集。
而我當然會鏈接到我的測試包目標中的框架。
此外，所有的框架標題都標記爲public。
我也嘗試將框架文件添加到測試包的目標並將它們排除。這些都沒有解決問題。
我對這裏出了什麼問題感到有些困惑，現在。有任何想法嗎？
這是怎麼了我的C++類是什麼樣子（種）：
//FooBar.hh
namespace Foo {
class Bar {
public:
bool baz() const;
}
}
//FooBar.mm
#import "FooBar.hh"
namespace Foo {
bool Bar::baz() const {
return true;
}
}
而且這是我的測試案例：
//FooBar_Tests.hh
#import <SenTestingKit/SenTestingKit.h>
@interface FooBar_Tests : SenTestCase
@end
//FooBar_Tests.mm
#import "FooBar_Tests.hh"
#import <TestFramework/FooBar.hh>
//this one fails as well (compiles fine, fails one linkage):
//#import "FooBar.hh"
@implementation FooBar_Tests
- (void)testBaz {
Foo::Bar bar();
STAssertEquals(bar.baz(), true, nil);
}
編輯：拆分代碼成.hh & .mm文件。儘管如此，仍然有相同的錯誤。
符號缺失是Foo :: Bar :: Bar（double *，unsigned int）和Foo :: Bar :: getComponent（unsigned int）const。這真的是完整的測試代碼嗎？必須有別的東西。 – 2012-07-23 16:24:58
@AndréPareis：哦，看起來像我不小心張貼了一箇舊的錯誤日誌（我的_original_代碼）。在試圖弄清楚什麼是錯誤的時候，我最終將類的代碼改爲上面發佈的（完全相同的）簡單代碼，並且仍然有相同的錯誤（但是當然有新的函數名），所以問題保持不變。修復錯誤日誌以反映更改。 – mtree 2012-07-23 18:27:55
