我已经下载了 expect5.4。我正在尝试为运行精简版 linux 的 ARM(PandaBoard) 交叉编译它。

在配置的初始设置中，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 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。

使用（小写）你会更进一步--host=arm，但不多：expect 只是不想被交叉编译。克服这一点需要对configure.in. 如果您只想交叉编译，那么对它们进行处理可能是合理expect的，但如果还有很多其他东西，您最好设置一些可以运行已编译二进制文件的环境（scratchbox或类似的东西）。

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

你可以

  1. 从项目中下载“buildroot 2019.11”。
  2. 提取它
  3. make pandaboard_defconfig在里面跑buildroot-folder

  4. 由于依赖关系，运行make menuconfig并启用TCL（-> 目标包 -> 解释器语言和脚本）然后（-> 目标包 -> 解释器语言和脚本）expect

  5. 运行make以构建整个事物并从 output/build/expect文件夹中获取可执行文件
