在交叉编译 gdb 8.2 时发生结构重新定义

Question

我想将 gdb 8.2 交叉编译到一个 arm64 设备中。 这是我要做的步骤：

1. mkdir build && cd build.
2. ../configure --host=aarch64-linux-gnu --target=aarch64-linux-gnu
3. 制作 然后我从输出中得到了重新定义的错误和成员未定义。

最奇怪的是，如果我不配置--host=aarch64-linux-gnu，编译就OK了。 但是我想把“gdb”放到我的开发板上，我该如何解决这个错误？ 我不知道为什么。请帮忙。

如何解决这个重新定义的错误？
