Question

我已下载expect5.4。我正在尝试交叉编译它为ARM（PandaBoard）运行剥离版本的linux。

在初始配置设置中，我尝试

Shell$ ./configure --host=ARM
configure: WARNING: If you wanted to set the --build type, don't use --host.
    If a cross compiler is detected then cross compile mode will be used.

更新在使用./configure --host = arm进行编译时，我现在得到的错误是

checking for sysconf... yes
checking for strftime... yes
checking for strchr... yes
checking for timezone... yes
checking for siglongjmp... yes
checking for memcpy... yes
checking if WNOHANG requires _POSIX_SOURCE... configure: error: Expect can't be cross compiled

它能够选择arm-gcc，但由于某种原因它失败了。

Answer 1

--host=arm（小写）你会得到更多，但不是很多：期望只是不想被交叉编译。克服这一点需要在configure.in中进行非平凡的修改。它可能是如果expect是你想要的唯一的东西，那就理性地对待它们交叉编译，但如果还有很多其他的，你最好设置一些您可以运行已编译二进制文件的环境（scratchbox或类似的东西）。

Answer 2

Expect（版本= 5.45.4）在buildroot 2019.11中可用，并且它支持PandaBoard。

您可以

从项目中下载“ buildroot 2019.11”。
提取它
在make pandaboard_defconfig内运行buildroot-folder
运行make menuconfig并启用TCL（->目标软件包 ->口译员的语言和脚本），然后是expect（->目标软件包 ->译员的语言和脚本）
运行make来构建整个程序并从 output/build/expect文件夹
