Thanks for your help.

I have tried adding libssh2.lib before/after two openssl library files. But
still the same linker errors are happening.

Below is the error which i received.

Doubt: Could you please clarify my doubt, is there any specific OpenSSL for
ARMV4i platform. (I am using the one I used for Win32 compilation). If yes
please share the link to download.

Please help to resolve these linker errors.
