मैं क्यूसीएआर एसडीके संकलित कर रहा हूं, लेकिन इस परियोजना में अधिक ढांचे को जोड़ने के बाद यह एक त्रुटि को संकेत देता है।एक्सकोड 4.2 में अज्ञात प्रकार का नाम 'नेमस्पेस'?
// Matrices.h
//
#ifndef _QCAR_MATRIX_H_
#define _QCAR_MATRIX_H_
namespace QCAR
{
/// Matrix with 3 rows and 4 columns of float items
struct Matrix34F {
float data[3*4]; ///< Array of matrix items
};
/// Matrix with 4 rows and 4 columns of float items
struct Matrix44F {
float data[4*4]; ///< Array of matrix items
};
} // namespace QCAR
#endif //_QCAR_MATRIX_H_
लाइन namespace QCAR में, यह Unknown type name 'namespace' कहा।
मुझे क्या करना चाहिए?
