Hello Team,
We have a requirement to do Port-forwarding. For that we thought of using LibSSH2.
We tried to compile the LIBBSSH2 source code of the version 2-0.9, which we are able to do it successfully after adding the external libraries from OpenSSL and zLib.
Now we have release version libssh2.lb file.
After that we tried to start with the example "direct_tcpip.c" which is available in the site. But whenever we tried to call any of the libssh2 definitions, we are getting into linker errors, which we were not getting the solution to fix this.
I am pasting the code and the errors below for your reference:
/*Didn't pasted the header files information here, which are same as the example in the site*/
int main(int argc, char *argv[])
{
int rc;
LIBSSH2_SESSION *session;
#ifdef WIN32
char sockopt;
WSADATA wsadata;
WSAStartup(MAKEWORD(2,0), &wsadata);
#else
int sockopt;
#endif
rc = libssh2_init (0);
/* Create a session instance */
session = libssh2_session_init();
}
1. If I try to call the function "libssh2_init(0);", I am getting the below error
"Error 2 error C3861: 'libssh2_init': identifier not found"
2. And if I try to call the function "libssh2_session_init()", I am getting linker error as shown below.
"Error 4 error LNK2001: unresolved external symbol "struct _LIBSSH2_SESSION * __cdecl libssh2_session_init_ex(void * (__cdecl*)(unsigned int,void * *),void (__cdecl*)(void *,void * *),void * (__cdecl*)(void *,unsigned int,void * *),void *)" (?libssh2_session_init_ex@@YAPAU_LIBSSH2_SESSION@@P6APAXIPAPAX_at_ZP6AXPAX0@ZP6APAX2I0_at_Z2@Z)"
This is the case for whatever function I call from my example program.
Please help us in getting this issue fixed.
We are using VS2005 on Windows XP Professional.
Regards,
Kalyan.Polasi
