转换的警告.类错误

我正在学习c++，在我现在正在做的作业中，我得到了一堆警告，我怀疑它们也导致了我得到的两个错误。问题是，显示警告的行是他给我们的行(其中之一)，所以我认为代码一定是正确的。这使我相信在我的类声明或构造函数中存在问题。有人能发现什么问题吗?

警告(对于fillSystemCommandList函数的每一行)是不支持从字符串文字到'char *'的转换

，错误为架构x86_64的未定义符号:"COMMAND::COMMAND(char*， int)"，引用自:在system_utilities.o中填充systemcommandlist ()没有找到架构x86_64的Ld:符号clang: error: link command failed with exit code 1(使用-v查看调用)

你可以跳过ParseCommandLine函数，我认为它很好。我只是包含它，以便我可以拥有整个文件(这不是我的主要btw)。

其他笔记:- systemCommands数组应该是长度为NUMBER_OF_COMMANDS的命令指针(我想我做对了)

- fillSystemCommandList函数应该用结构体填充systemCommands数组，这些结构体包含指向命令字符串的指针和相应的定义常量。

-I知道这段代码几乎全是C语言，这也是因为我选的是c++入门类。
