C Library for Telegram bot API that uses json-c and libcurl. Head over to Telegram Bots page to read about how to register your brand new bot with Telegram platform and see it in action using telebot.
You need to install libraries and build tools such as CMake. On Debian-based Linux distributions you can do it as follows:
sudo apt-get install libcurl4-openssl-dev libjson-c-dev cmake binutils makeOn Mac OSX, first install macports from MacPorts and in Terminal
sudo port install cmake json-c curlTo build the library run following commands:
cd [your repository] mkdir -p Build &&cd Build cmake ../ makeSample
Following sample creates a simple dummy bot which echoes back the messages sent to it. The same example is built as echobot executable under Build/test folder. The executable expects and reads bot token from .token file on the same location.
