我编译qt5.6源码时 ，make出错，Ubuntu报错如下，大神们帮忙看看

libatomic.so.1 貌似缺这个文件
我看了目录，有这个文件。。。。。
gsk@gsk-machine:~/licheepi/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabi/arm-linux-gnueabi/libc/lib$ ls -l libatomic.*

libc用的是哪个版本?
应该就是 libc2.25了

是不是用了uClibc，要glibc才行的
额，解决了，是链接库出问题了，在 qmake.conf 文件中，在QMAKE_LINK 后加上 -latomic就好了，但是又出了新问题。。。。。，一部分log如下，是不是我的编译器有问题啊，哎
