7，经验总结
strace交叉编译2小时就好了，ltrace花了2天时间！！！需要反思的一下：
（1）编译之前先看看文档，确认支持的版本；
（2）出错时认真分析日志文件，比如（config.log、实时打印输出的编译指令），一般会找到出错原因；
（3）交叉编译时思路要清晰，不要把依赖库的版本搞混，用x86_64的库去编译aarch64肯定会有问题；
（4）网上的参考贴好多都是年代久远，对新出的aarch64支持不友好，需要下载最新版本，对照源码文件文档进行编译；
（5）开源软件绝大多数都是用相同的发布机制进行管理的，一般是 autoconf + ./configure 生成Makefile；
（6）需要回炉一下编译、链接的过程，注意 -Wl,-rpath-link,DIR || -Wl,-rpath=DIR || -L DIR|| LD_LIBRARY_PATH=DIR的作用与区别；
（7）尽可能不要动开源软件的代码，大多数问题可以通过指定配置参数来规避。
