我正在尝试为基于 arm 的板交叉编译 lftp-4.3.5。我将配置文件执行为：
"./configure --host=arm-montavista-linux CXX=arm-montavista-linux-gnueabi-g++ CC=arm-montavista-linux-gnueabi-gcc --with-openssl=/abcd/xxx/yyy/ssl with_included_readline =没有”
我不得不稍微修改一下配置文件。我添加了“i_cv_posix_fallocate_works=yes”因为我遇到了类似的错误
checking for pty.h... yes
checking for library containing openpty... -lutil
checking for _getpty... configure: error: in `/home/xxxx/yyyy/lftp-4.3.5':
checking whether posix_fallocate() works... no
configure: error: cannot run test program while cross compiling
See `config.log' for more details
我无法得到解决方案，所以我像这样修改它并摆脱了这种阻塞。
现在它要求 readline 库，我下载了 lib 源代码（readline-6.2）并交叉编译它。在运行 make 文件时，make 脚本没有从给定位置获取交叉编译的 libreadline.a 文件（我在运行 configure 时添加了 --libdir 路径）。无论如何，我能够提供这个库来制作脚本，但是当脚本读取这个库时，它抛出了很多错误：

现在： 1.是否有人可以帮助我解决这里的问题？2.或者无论如何我可以跳过这个readline lib的添加？（'--with-readline=no' 选项未在配置文件中配置）。
我试图从 4-5 天开始交叉编译，但仍然坚持这一点。任何人都会帮助我。
谢谢，拉胡尔
