我必须继续一个程序。我之前的程序员经常使用这种结构:
std:vector< T* const>
他在 Visual Studio C++ 2010 中编写了 ist 并且能够编译它。我正在使用 g++,它会引发一些编译错误。
g++ -g -Wall -c -std=c++11 -pedantic -I/usr/include/SuperLU/ src/Cell.cpp -o obj/Cell.o

他想要这个结构是一个指针向量,他可以在其中添加和删除指针并操作指针的目标,但不能更改指针指向的对象。
据我了解,它不应该编译,因为 T* const 是不可分配的。
有谁知道它为什么在 Visual Studio 中编译?我可以在声明中替换它而不需要更改完整的代码吗?
