但是我收到以下错误:
/usr/bin/ld: /tmp/cct6xeXD.o: undefined reference to symbol
'pthread_join@@GLIBC_2.4' //lib/arm-linux-gnueabihf/libpthread.so.0:
error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
我不知道这个错误是什么意思.任何帮助将不胜感激.
I have no idea what this error means. Any help will be greatly appreciated.
推荐答案
DSO 这里的意思是动态共享对象；由于错误消息说命令行中缺少它，我想您必须将其添加到命令行中.
DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.
也就是说，尝试将 -lpthread 添加到您的命令行中.
That is, try adding -lpthread to your command line.
