Cannot run this sample

[baptose]

Hi,

I am fairly new to c++ building tools, and I cannot get this to compile. I have git cloned BT.cppv4 and follow the conan/cmake build instructions, with an additionnal cmake --install . from the build directory. Everything went fine.

I git cloned this sample repo, and when I run something like :

> cd btcpp_sample
> mkdir build;cd build
> cmake ..

I get the following

-- The CXX compiler identification is GNU 11.4.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++ - skipped
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Configuring done
CMake Error at CMakeLists.txt:8 (add_executable):
  Target "btcpp_sample" links to target "SQLite::SQLite3" but the target was
  not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?

I'd really appreciate any help.

Thanks

@baptose This is probably too late of a response. However, hope this helps anyone new trying to get btcpp_sample to work.

Cause Of Issue 🔍

The sqlite3 dependency seems to be missing from your local environment, thus causing CMake to throw an error trying to find it.

A quick way to address this missing dependency is to run the following command (assuming you are running in a Linux operating system):

sudo apt-get install libsqlite3-dev -y

However, that might not be the only missing dependency you have so to have a sure-fire to run btcpp_sample, please follow the steps below.

Instructions 📘

1. Create a simple workspace:

mkdir btcpp_sample_ws && cd btcpp_sample

2. Download the repository:

git clone https://github.com/BehaviorTree/btcpp_sample.git --depth 1 --single-branch && cd btcpp_sample

3. Create the Dockerfile below:

touch Dockerfile

FROM ubuntu:22.04
ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update && \
    apt-get install -y \
    build-essential \
    cmake \
    git \
    libzmq3-dev \
    libsqlite3-dev \
    libgtest-dev && \
    rm -rf /var/lib/apt/lists/*

WORKDIR /usr/src/btcpp

RUN git clone https://github.com/BehaviorTree/BehaviorTree.CPP.git . --depth 1 --single-branch --branch 4.7.0

RUN mkdir build && \
    cd build && \
    cmake .. -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_SHARED_LIBS=ON && \
    make -j$(nproc) && \
    make install

WORKDIR /usr/src/
COPY btcpp_sample btcpp_sample
WORKDIR /usr/src/btcpp_sample

RUN mkdir build && \
    cd build && \
    cmake .. && \
    make -j$(nproc)

WORKDIR /usr/src/btcpp_sample/build

CMD ["./btcpp_sample"]

4. Build the docker image:

docker build -t btcpp_sample:latest .

5. Run btcpp_sample in a docker container:

docker run -it --rm \
	--name btcpp_sample_c \
btcpp_sample:latest bash -c "./btcpp_sample"

Verify ✔️

You should see the following output to know that it worked:

this works too
