^^^^^^^^^^^^^^ There's the problem—curl was built from git but it's using an older libcurl. You need to make sure the executable built from git is using the libcurl built from git by e.g., using LD_LIBRARY_PATH or -rpath when linking.

I don't have experience on using this option for curl compile. Could you please give the corresponding commands?

[dfandrich]

The quickest way around the problem is to run curl with: LD_LIBRARY_PATH=/path/to/your/libcurl curl www.baidu.com where the file /path/to/your/libcurl/libcurl.so.4 is your home-built libcurl.

[hongyi-zhao]

Still not so clear.

I only using the make to make curl, and don't know how to make libcurl.

[hongyi-zhao]

Got it, the make will also make libcurl and put it in the following location:
LD_LIBRARY_PATH=/usr/local/lib curl www.baidu.com
