Error: Can't create download thread.

[lms1206]

平台 树莓派3b arm
ubuntu16.04lts
使用synch -r参数 下载几个文件之后会出现这个报错
在sudo screen里运行也是一样会报错
是我编译的时候遗留的bug???

执行make编译时报这个错误
/usr/bin/install: cannot create regular file '/usr/local/lib/libbaidupcs.so.0.0.0': Permission denied
Makefile:522: recipe for target 'install-libLTLIBRARIES' failed
make[1]: *** [install-libLTLIBRARIES] Error 1
make[1]: Leaving directory '/home/ubuntu/pcs-make/BaiduPCS'
Makefile:1297: recipe for target 'install-am' failed
make: *** [install-am] Error 2

执行./configure 时的错误找不到log了...
如果需要的话我愿意提供帮助
