我在

xconfig

工具中搜索

host-heimdal

但什么也没找到。 为什么会失败？我的意思是，我没有对其配置进行任何更改。

更新

• Buildroot版本：2024.08-rc3
• 下载方式：git克隆
• 主机版本：Ubuntu 24.04

Answer 1

根本原因是 heimdal 的 autoconf 宏中的错误。

作为一种快速解决方法，您可以将

ac_cv_sys_large_files=1 ac_cv_sys_file_offset_bits=64

添加到 heimdal.mk 中的

HOST_HEIMDAL_CONF_ENV

。

问题是heimdal的配置脚本使用了

AC_SYS_LARGEFILE

宏，然后使用了其内部的

ac_cv_sys_large_files

和

ac_cv_sys_file_offset_bits

变量。这些变量在该宏的最近更新中已被删除。

正确的修复可能是删除上游 heimdal 的配置脚本中对大文件的特殊处理。但我不知道为什么首先引入它......
