主要是弹窗让我安装 m4, 安装了下次编译还给我弹出来，这有办法破解吗？

[ShuA1]

出现这个问题通常是因为缺少 m4 工具或路径配置问题，特别是如果在 macOS 或 Linux 系统中。如果你已经安装了 m4 ，但编译过程仍提示需要安装，可以尝试以下解决方案：

1. 确认 m4 是否正确安装
首先，确保 m4 已正确安装并且在系统路径中可用。你可以运行以下命令检查：
> which m4
如果 m4 已安装，此命令应返回 m4 的路径。如果未安装，可以使用以下命令进行安装：

macOS (使用 Homebrew):
> brew install m4

2. 确认路径
有时候，即使安装了 m4 ，系统路径中可能没有包含它。可以手动添加路径：
> export PATH=/usr/local/bin:$PATH
将 /usr/local/bin 替换为 m4 安装路径所在的位置。

3. 清理缓存和重新编译
有时候，CMake 的缓存会导致问题。尝试清理缓存并重新生成 Makefile：
> cd /path/to/your/build
> rm -rf *
> cmake .. -DWITH_DEBUG=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/Users/zjp/Projects/mysql-server/build/boost -DCMAKE_INSTALL_PREFIX=/Users/zjp/Projects/mysql-server/build/install -DMYSQL_DATADIR=/Users/zjp/Projects/mysql-server/build/install/data
> make -j8
4. 使用 autoreconf
在某些情况下，m4 需要 autoconf 配合工作。可以尝试安装 autoconf 并使用 autoreconf：
macOS:
> brew install autoconf

然后在源码目录运行：
> autoreconf -i

5. 检查权限
确保你有足够的权限执行 m4 以及所有相关工具。如果使用的是 macOS ，可能需要通过 sudo 安装工具：
> sudo brew install m4

6. 验证 m4 版本
有时候，编译可能需要特定版本的 m4 。你可以检查版本并更新：
> m4 --version

如果这些步骤无法解决问题，请提供更多的编译错误日志以便进一步诊断。
