ofstream错误:error: variable ‘std::ofstream ofs’ has initializer but incomplete type

简介: ofstream错误:error: variable ‘std::ofstream ofs’ has initializer but incomplete type

在使用std::ofstream写文件时,编译器提示如下错误:

error: variable ‘std::ofstream ofs’ has initializer but incomplete type
         std::ofstream ofs(string(TMP_STATE_FILE));


这个错误上由于没有保护头文件导致的。


包含上头文件,编译通过。
