Using liboauth - unresolved externals?

Hi everybody,

I'm messing around with OAUTH at the moment - just to see if I can talk to Twitter's servers. However, as soon as I use an OAUTH function, I get a load of unresolved externals. The missing functions seem to be related to OpenSSL but even when I link with -lamisslauto, nothing changes.

How do I use liboauth, can anybody help?

Thanks if anyone can!

This is the first bit of the output (my program is called "Ribbet" :) )

5.Work:coding/Ribbet> gcc main.c -lamisslauto -loauth       
/SDK/local/newlib/lib/liboauth.a(liboauth_la-oauth.o): In function `oauth_gen_nonce':

First your order of link libraries is wrong. Libraries that depend upon other libraries should come before the libraries they depend upon on the command line as the compiler only links in those objects from libraries that are needed to resolve undefined references and objects/libraries are linked in the order they are specified.

Second you should probably be using these openssl libraries instead:

The AmiSSL OpenSSL is pretty ancient and unlikely to be updated any time soon.

What about the reply that I made to you on OS4coding ?

"For Qt ports who need ssl, I use that :
"-lssl -lcrypto"

Certainly not your need, but with luck...."

-lssl is for openssl.

Ah, yes, just saw that. Didn't get a notification for some reason.
No crypto lib I can find but I guess it's part of libssl.

Thanks for the help, will give it a try when I can!
