I know why curl report No URL Set Error.
There are some bugs in the latest two commits.
If i switch to "40597fd git ignore src/config-win32.h", It works ok.
It seems that i git clone ok while using socks proxy, but I can't find any information about socks proxy.
so i doubet socks proxy was not used?
or the modification of libcurl was so usefull that i can go through the internet without proxy?
