调研方向

从 ansible/roles/baselayout/tasks/main.yml 中的 package-install 任务以及 ansible/MANUAL_STEPS.md 中引用的 install-clang-backend 部分开始。重现 AIX 7.2 OSUOSL 失败，然后验证安装 IBM_OPEN_XL_CPP_RUNTIME_17.1.4.1_AIX.tar.Z 的内容可以解析 libunwind.a、libc++.a 和 libc++abi.a，从而使 playbook 成功安装 rust、cargo 和 rustfmt。

描述

When attempting to deploy the playbooks on the AIX 7.2 machines at OSUOSL there is a dependency problem showing up. This did not affect the IBM machines (which already had rust installed):

This is from the AIX system package libunwind.rte which is part of the IBM_OPEN_XL_CPP_RUNTIME_17.1.4.1_AIX.tar.Z package archive from IBM so that will need to be installed in order to resolve this. Ref: https://github.com/nodejs/build/blob/main/ansible/MANUAL_STEPS.md#install-clang-backend
