First of all, great project and thanks for providing this.

Unfortunately I have problems running the plugin in pidgin 2.13.0. A connection is established (the connection with openMittsu is interrupted as soon as pidgin connects) but I encounter the following issues:

• Adding a user is not possible, since the account is not shown in the drop down list for selection the threema account (on Debian 10 with Gnome)
• Adding a user crashes pidgin (on Ubunut 18.04 LTS with Gnome) but the account is available in the drop down list
• Sending an message to a new user (user name = threema id?) opens a chat window but any message sent just disappears without being echoed in the chat window
• Receiving a message does not open a chat window but gives the error message: "Unsupported TLS library used by CURL"

Maybe it is just some sort of mis-configuration, is there any kind of readme or documentation?

Best, Torsten

First, thanks a lot for writing this plugin!

I'm trying to install it, and the build looks successful (some warnings), but in Pidgin, the "Add Account" dialogue doesn't list anything related to Threema, and the "Debug Window" shows the following upon opening "Tools" > "Plugins" (where the plugin doesn't appear either):

(17:49:13) plugins: probing /home/sabine/.purple/plugins/libceema.so
(17:49:13) plugins: /home/sabine/.purple/plugins/libceema.so is not usable because the 'purple_init_plugin' symbol could not be found.  Does the plugin call the PURPLE_INIT_PLUGIN() macro?

Looks like this refers to this definition:

Do you know what could be going on there? Thanks a lot!

OS: Fedora 32, 64-bit
Kernel: 5.7.8-200.fc32.x86_64, gcc version 10.1.1 20200507 (Red Hat 10.1.1-1)
Pidgin version: 2.13.0-18.fc32 (libpurple 2.13.0)

Hello, as you may have noticed, the log-in server at g-xx.0.threema.ch disappeared some time last fall. Are there any known alternatives? Or is this library (and purple/Pidgin plug-in) essentially dead without it?

openMittsu is still working, so I’m trying to figure out what's going on.

From reading its source code, it looks like xx of the hostname should be replaced with digits. However, when I try that with a couple of values I only get an error message:

Unable to decrypt HELLO packet

They all point to the same two IP addresses 185.88.236.90 and 185.88.236.110, so I doubt that the specific digits matter.

The libpurple plugin that you've written wouldn't be license-compatible with libpurple as libpurple is GPL and ceema uses OpenSSL which has GPL-incompatible licensing terms.

Can OpenSSL be removed from the project so that it can become GPL-compatible?

Since yesterday I can’t log into Threema using Pidgin with threepl any longer. Whenever I try I get a pop-up dialogue:

• Window title: Login Error
• Message title: Invalid output size
• Message: Invalid username, password or backup string
• Available buttons: close

Considering that I changed none of my log-in data recently I doubt that that’s the actual issue.

• Pidgin and libpurple version: 2.14.10
• ceema/threepl version: 8f2d466

Pidgin’s debug log contains nothing of relevance regarding the log-in process:

Any idea what might be wrong?

During make I get the following error:

make[2]: *** No rule to make target '<parentdir>/ceema/3rdparty/curl/lib/libcurl.so', needed by 'libceema.so.0.0.1'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:118: src/CMakeFiles/ceema.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

I have installed: sudo dnf install libcurl-devel libcurl
I am confused why make needs something from /3rdparty/curl since this directory or submodule does not exist in the repository.

What do I need to make this libcurl.so available?

Sorry to create an issue even though I expect that I need to change something, not ceema. I don't see another way of asking for support.

Btw: to get to this point, the following installations were necessary on Fedora 37:
sudo dnf install openssl-devel libsodium-devel curlpp-devel mbedtls-devel

Starting today I receive the error message in the title when I try to connect to my Threema account via Pidgin (v2.14.10). Pidgin then disables the account. Is that some protocol change that threepl/ceema don’t support (yet)? Note that I had to change the server configuration as per #5.

Is there some further info or logs that you need to debug the issue?

I've compiled the pidgin plugin and could basically add a Threema account.
But how / what do I need to enter for Username / Password?
