我想从 autoconf 2.62 更新到 2.69。
我下载了源代码并运行了以下命令：
./configure
make
make install
这些都顺利完成。
当我运行时，autoconf --version我得到以下信息：
autoconf --version

您在这里看到的问题是版本报告为?K?? .
为什么会这样？我的机器在 EBCDIC 代码页中运行，我想知道这是否可以关联。是否有我需要添加的配置/制作选项。
这个问题使我无法编译其他软件，因为配置脚本会检查 autoconf 报告的版本，但最终无法通过这些检查。
-----UPDATE------- 我已make check按要求运行，这是输出：

我的眼睛被吸引到：m4:local.at:18: bad expression in eval (bad input): ((?+1+0) > (2+0)) - ((?+1+0) < (2+0))- 任何想法为什么这可能被认为是一个糟糕的表达？
