I want to use openssl on my ARM platform,so I need to cross compile it.I download the openssl-1.0.1c from the openssl.org.I used arm-linux-gcc(libc2. 2.5) to comlile it successfully,getting libssl.a ,libcrypto.a and openssl.But when I run openssl on my ARM with the command "./openssl s_client -connect smtp.gmail.com:465 -state",it got error.the messages is "CONNECTED(00000003) SSL_connect:before/connect initialization SSL_connect:error in SSLv2/v3 write client hello A write:errno=0 --- " error on *write*, and with errno=0? That's very weird. Write on a TCP socket immediately after connecting should never fail. Leave openssl out of the picture for a moment. If you (cross)compile a program which just does a plain TCP socket connection, does it work? (Since you want access to gmail, you might try connecting to www.google.com 80, sending the simplest possible HTTP request: GET / HTTP/1.0\r\n\r\n and seeing if you get any reply data (probably doesn't matter what, although it should be an HTML page), or some socket/OS error. the similar problems ,I made a test program with libssl.a ,libcrypto.a which I cross compiled . SSL_connect function return -1,I use SSL_get_error ,i got the errno 5(SSL_ERROR_SYSCALL),and ERR_get_error to check,it return 0,I find the documents which says " If ret == 0, an EOF was observed that violates the protocol." I don't know what's the meaning and how to solve it. Note 'ret == 0' in SSL_get_error manpage means the return from SSL_connect (passed to SSL_get_error) not the return from ERR_get_error. You say SSL_connect returned -1, so read the next sentence to cover that case, and as it says on Unix look at errno.
