Hello

I have good idea :]
We haven't jabber component.
It is open source instant comunication protocol.

I am poor in coding components in lazarus
And I can't make that component.
But maby someone can write it

There still isn't a jabber component?

Greetings

I've tried this out (using the version on GitHub that is slightly
newer and comes with all the required libraries).

On Windows when I try to login I get output, but it doesn't connect:

=> <?xml version="1.0"?>
=> <stream:stream to="gmail.com"  xmlns="jabber:client"
xmlns:stream="http://etherx.jabber.org/streams"  version="1.0">

<= <proceed xmlns="urn:ietf:params:xml:ns:xmpp-tls"/>
ERROR: 10091,

On Mac I simply get an error with no output:

dxmpp
Semaphore init failed (possibly too many concurrent threads).

Quotedxmpp
Semaphore init failed (possibly too many concurrent threads).On *nix,
chtreads unit must be used (and it has to be the first unit in the
.lpr uses clause).

Also, a link to the github repository would be nice - if only for
reference

Thanks!

Thanks for the tip!  That at least got me output on the Mac side,
though it is still not working on either side.  The output I get on
the Mac is as follows:

=> <?xml version="1.0"?>
=> <stream:stream to="gmail.com"  xmlns="jabber:client"
xmlns:stream="http://etherx.jabber.org/streams"  version="1.0">
<= <stream:stream from="gmail.com" id="DBF626B9A9237ADF" version="1.0"
xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client">
<= <stream:features><starttls xmlns="urn:ietf:params:xml:ns:xmpp-
tls"><required/></starttls><mechanisms

chanism><mechanism>X-OAUTH2</mechanism></mechanisms></stream:features>
=> <starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/>
<= <proceed xmlns="urn:ietf:params:xml:ns:xmpp-tls"/>

For anyone else following along I've figured out another big chunk of
what was wrong.  To start I Googled for the protocol and once found
followed along with the connection and what it should look like.  You
can find out what a Google Talk connection should look like at the
low-level here:

https://developers.google.com/cloud-print/docs/rawxmpp

Then, I noticed where the error occurred.  That is, it occurred right
where the SASL Authentication Handshake should begin.  That suggested
an error in the SSL Library or the SASL unit.  Some fiddling around
with the SSL Library and I discovered this code in ssl_openssl_lib.pas
(which is strait from the GitHub):

 Code: [Select] {$IFNDEF WIN32}
  DLLSSLName: string = 'libssl';
  DLLUtilName: string = 'libcrypto';
  {$ELSE}
  DLLSSLName: string = 'ssleay32.dll';
  DLLSSLName2: string = 'libssl32.dll';
  DLLUtilName: string = 'libeay32.dll';
  {$ENDIF}

Now, it seemed a little funny to me that Unix was the one using the
DLL's, so I swapped it around.

Code: [Select]{$IFNDEF UNIX}
  DLLSSLName: string = 'libssl';
  DLLUtilName: string = 'libcrypto';
  {$ELSE}
  DLLSSLName: string = 'ssleay32.dll';
  DLLSSLName2: string = 'libssl32.dll';
  DLLUtilName: string = 'libeay32.dll';
  {$ENDIF}
And guess what... It connected just fine.  At least on Windows it
did.  I still have to check it out for Mac.

Works on Mac now too and tested person-to-person messaging, which also
works.

Great! I have some use for a Jabber unit in FPC... going to remember
this.

Perhaps this is something for the Lazarus CCR repository
