Я c++ всерьез начал заниматься недавно, и сегодня у меня вылезла ошибка, которую я раньше никогда не встречал: error: cannot delete expression of type 'char' Вылазит она, собственно, здесь: C++1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Buffer::Buffer( long int start_size ) { cannot delete pointer = new char[start_size]; size = start_size; actual_size = 0; } Buffer::~Buffer( void ) { delete pointer[size]; // здесь } void Buffer::resize( long int new_size ) { char* new_pointer = new char[new_size]; if ( actual_size > new_size ) actual_size = new_size; memcpy( new_pointer, pointer, actual_size ); delete pointer[size]; // и здесь size = new_size; cannot delete expression pointer = new_pointer; }Вот класс: C++1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 class Buffer { public: Buffer ( long int start_size ); ~Buffer ( void ); void resize ( long int new_size ); char* getDataPointer ( long int offset ); char* getData ( long int offset, long int data_size ); int setData ( char* data_pointer, long int data_size, long int buffer_offset ); long int getSize ( void ); long int getMaxSize ( void ); void clear ( void ); protected: char* pointer; long int size; long int actual_size; };Хотелось бы узнать, что это за ошибка, по какой причине возникает и как с ней бороться. Заранее всем благодарен. Similar Эксперт 41792 / 34177 / 6122 Регистрация: 12.04.2006 Сообщений: 57,940 23.02.2012, 03:52 error: cannot delete expression of type
17758] calling double-precision sqrt with a float: not so fast, fast-math Next message: [LLVMbugs] [Bug 21340] warning: "cannot delete expression with pointer-to-'void' type 'void *'" missing -W flag Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] http://llvm.org/bugs/show_bug.cgi?id=21340 Bug ID: 21340 Summary: warning: "cannot delete expression with pointer-to-'void' type 'void *'" missing -W flag Product: clang Version: unspecified Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P Component: -New Bugs Assignee: unassignedclangbugs at nondot.org Reporter: fuscated at gmail.com CC: llvmbugs at cs.uiuc.edu Classification: Unclassified Save this snippet as delete_void.cpp int main() { void *a=new char[100]; delete [] a; return 0; } Then execute: $ clang++ delete_void.cpp delete_void.cpp:3:2: warning: cannot delete expression with pointer-to-'void' type 'void *' delete [] a; ^ ~ 1 warning generated. There is a warning, but there is no -W flag, so we cannot force it into error and thus automatically prevent such bugs creeping in the code-base. Tested with both 3.4 and 3.5. -- You are receiving this mail because: You are on the CC list for the bug. -------------- next part -------------- An HTML attachment was scrubbed... URL:
