出于某种原因，我无法让NTP libs交叉编译。在我未经训练的眼睛看来，这是交叉编译手臂。但是，当我做$file的时候，它们并没有显示为ARM。

最佳答案
你试着照上面说的做了吗？
/configure --with-yielding-select=yes -prefix=$(pwd) CC=~/development/trunk/build_tools/arm-2010q1/bin/arm-none-linux-gnueabi-gcc LD=~/development/trunk/build_tools/arm-2010q1/bin/arm-none-linux-gnueabi-ld AS=~/development/trunk/build_tools/arm-2010q1/bin/arm-none-linux-gnueabi-as --host=arm-linux CFLAGS=-static
尽管我已经安装了openssl，但在make过程中我做了那件事，然后得到了一个
"missing openssl/bn.h"错误。通过添加
--with-openssl-incdir="/usr/include"作为配置选项来解决此问题。现在尝试解决配置过程中出现的“错误：系统上必须有stdarg.h或varargs.h”错误。如果我解决的话会回来的。关于linux - 无法使NTP交叉编译到ARM，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/40470198/
