我已经下载expect5.4 。 我试图交叉编译ARM（PandaBoard）运行精简版的Linux。
在configuration的初始设置，我尝试
Shell$ ./configure --host=ARM configure: WARNING: If you wanted to set the --build type, don't use --host.

它能够selectarm-gcc但由于某种原因失败。
你会得到一个更进一步的 – --host=arm （小写），但不是很多：期望只是不想交叉编译。 克服这个问题需要在configure.in进行非平凡的修改。 如果expect是唯一想要交叉编译的东西，那么对它们进行处理可能是合理的，但是如果还有其他的东西，那么最好设置一些可以运行编译后的二进制文件的环境（ scratchbox或类似的东西）。
