Build instructions for CMake using Docker

Obtain your API credentials

You will require api_id and api_hash to access the Telegram API servers. To learn how to obtain them click here.

Clone source code

git clone --recursive https://github.com/telegramdesktop/tdesktop.git

Prepare libraries

Go to the tdesktop directory and run

docker build -t tdesktop:centos_env Telegram/build/docker/centos_env/

Building the project

Make sure that you're still in the tdesktop directory and run (using your api_id and api_hash)

docker run --rm \
    -v $PWD:/usr/src/tdesktop \
    tdesktop:centos_env \
    /usr/src/tdesktop/Telegram/build/docker/centos_env/build.sh \
    -D TDESKTOP_API_ID=YOUR_API_ID \
    -D TDESKTOP_API_HASH=YOUR_API_HASH \
    -D DESKTOP_APP_USE_PACKAGED=OFF \
    -D DESKTOP_APP_DISABLE_CRASH_REPORTS=OFF

Or, to create a debug build, run (also using your api_id and api_hash)

docker run --rm \
    -v $PWD:/usr/src/tdesktop \
    -e DEBUG=1 \
    tdesktop:centos_env \
    /usr/src/tdesktop/Telegram/build/docker/centos_env/build.sh \
    -D TDESKTOP_API_ID=YOUR_API_ID \
    -D TDESKTOP_API_HASH=YOUR_API_HASH \
    -D DESKTOP_APP_USE_PACKAGED=OFF \
    -D DESKTOP_APP_DISABLE_CRASH_REPORTS=OFF

The built files will be in the out directory.
