Question

我正在尝试为我的基于arm的电路板交叉编译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 = no“

我不得不稍微修改配置文件。我添加了“i_cv_posix_fallocate_works = yes”因为我遇到了错误

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这样修改了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lib来制作脚本，但是当脚本读取这个lib时，它会抛出许多错误：

现在：如果有人能帮我解决这个问题吗？ 2.或者通过任何方式我可以跳过添加这个readline lib？（'--with-readline = no'选项未在配置文件中配置。）

我试图从4-5天开始进行交叉编译，但仍然坚持这一点。任何人都会帮助我。

谢谢，拉胡

考虑到未定义的引用，例如tputs（http://linux.die.net/man/3/tputs），它们似乎是ncurses库（http://www.gnu.org/software/ncurses/）的一部分。您需要交叉编译并与ncurses链接。
