CMakeLists error on building in docker

[b166er]

Steps to reproduce:

mkdir /tmp/test
git clone https://github.com/tdlib/telegram-bot-api.git /tmp/test/
cd /tmp/test/telegram-bot-api
docker run --rm -it -w /app -v $PWD:/app ubuntu:latest bash
apt update
apt install make git zlib1g-dev libssl-dev gperf cmake g++
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..

Output:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.


CMake Error at CMakeLists.txt:16 (add_subdirectory):
  The source directory

    /usr/src/app/td

  does not contain a CMakeLists.txt file.


CMake Error at CMakeLists.txt:40 (include):
  include could not find requested file:

    PreventInSourceBuild


CMake Error at CMakeLists.txt:41 (prevent_in_source_build):
  Unknown CMake command "prevent_in_source_build".

You are running cmake from /usr/src/app/td as specified by thr error.

You should use https://tdlib.github.io/telegram-bot-api/build.html to build the Bot API server.

Thanks for the hint! I followed the instructions and tried it without root permissions as recommended, and that was the solution. without root, I found a missing write permission on the root directory. after adding chmod 777 to the /app directory (in the docker container), the build process completed successfully.

update: I found the main reason! in the first attempt I did manually "git clone" (without copy from instruction-site) on the host system (outside of docker container) to then build in the docker container, and in the git-clone I forgot the recursive parameter (like on instruction-site), so the submodule in the td folder was not pulled!

For those who want to run in Docker, here is my Dockerfile example

./my-Dockerfile

# Base layer with dependencies and building
FROM ubuntu AS base

COPY ./telegram-source /app
WORKDIR /app
RUN DEBIAN_FRONTEND=noninteractive && ln -fs /usr/share/zoneinfo/Europe/Berlin /etc/localtime \
    && apt update && apt -y upgrade \
    && apt -y install make zlib1g-dev libssl-dev gperf cmake g++ \
    && rm -rf build && mkdir build data && cd build \
    && cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=.. .. \
    && cmake --build . --target install


# top layer with custom entrypoint (env-catcher)
FROM base AS telegram

COPY ./my-entrypoint.sh /app/bin/entrypoint.sh
RUN chmod 755 /app/bin/entrypoint.sh

ENTRYPOINT [ "/app/bin/entrypoint.sh" ]

./my-entrypoint.sh

docker compose up -d and you will get a ready-builded and already running telegram-bot-api process.
