编译步骤：

1. git clone https://github.com/oceanbase/miniob.git
2. cd miniob
3. sudo bash build.sh init --这一步ok
4. bash build.sh --这一步报错
5. 查看已经生成了 二进制文件

6. 启动observer ./observer

7. 启动客户端 `./obclient`， 执行基本的show/select报错，不确定是否为编译的问题

➜ bin git:(main) ✗ ./obclient

编译过程中打印信息如下：

执行sudo bash build.sh init 的输出（看起来没有error）：

observer和obclient编译都成功了，执行SQL错误是因为你的SQL确实有问题，比如当前不支持show databases命令。 编译出问题的这个是一个单测。我本地也是apple m1+clang 14,但是无法重现你的问题。

[hnwyllmm]

看报错信息是由于lambda中某些变量没有捕获导致的，可以把 ranges::for_each 改成 for 写法，或者把lambda的参数捕获改成 &，比如

ranges::for_each(buffer_pools, [](DiskBufferPool *buffer_pool) {
        Frame *frame = nullptr;
        ASSERT_EQ(RC::SUCCESS, buffer_pool->allocate_page(&frame));
        ASSERT_EQ(RC::SUCCESS, buffer_pool->unpin_page(frame));
      });

改成：

ranges::for_each(buffer_pools, [&](DiskBufferPool *buffer_pool) { // [] 变成了 [&]
        Frame *frame = nullptr;
        ASSERT_EQ(RC::SUCCESS, buffer_pool->allocate_page(&frame));
        ASSERT_EQ(RC::SUCCESS, buffer_pool->unpin_page(frame));
      });

再另外的一台m1 电脑上编译，也没有此问题，忽略掉好了。感谢回复～
