目前 ( 2019/04/24 )，在 macOS Mojave (10.14.4)系统上使用 brew install octave ，安装 Octave 5.1.0 之后，使用 pause() 函数无法在点击键盘之后继续执行，除了 Ctrl + C 之外任意键都不响应。正常情况下，点击任意按键之后，应该继续执行后续的代码。
这个是目前使用 brew 安装的 Octave 5.1.0 在编译的时候，关联的库是 glibc 2.28 之后的版本。这个版本上 glibc 2.28 的某些行为发生变动。具体的讨论信息，参考 bug #55029: pause() with no arguments does not return like kbhit() with glibc 2.28 上的讨论。本质就是 glibc 2.28 之后的版本要求应用程序在接收信息结束（ EOF ）之后，主动调用 clearerr (stdin); ，否则会收不到后续的按键通知。这个 BUG 在 Octave 5.2 版本被修复，但是这个版本何时发布，暂时不定。
目前的修复方式为要求 brew 从最新版本的代码编译安装，而不是安装已发布版本，如下：
|
1 2 3 4 5 6 7 8 9 10 |
$ brew uninstall --ignore-dependencies octave # 安装编译依赖 $ brew install texinfo $ wget https://raw.githubusercontent.com/Homebrew/homebrew-core/master/Formula/octave.rb $ sed -i "" "s/\"--enable-shared\"/\"--enable-shared\",\"--disable-docs\"/g" octave.rb $ brew install --build-from-source --HEAD -v octave.rb |
修改下载的编译配置文件,并且关闭文档编译( 目前文档编译会失败），也就是增加 --disable-docs 这个编译参数。
调整之后的编译脚本如下：
