BaseClientQt example implementation

[rickbassham]

I'm looking for an example on using the BaseClientQt class.

1. When installing libindi-dev, I can't find the necessary include file.
2. When installing from source with the following command, I can find the include file, but get an error when linking.

cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DINDI_BUILD_QT5_CLIENT=ON ../indi
make
make install

Does anyone make use of this class, and can you point me to what I'm doing wrong here? Code I'm using to test this is located here: https://github.com/rickbassham/indi-qt-test

I'm new to QT programming, but not new to C++, so I may be just missing something easy.

On which OS is this? I can build this fine in GIT without any errors.

I'm running it in a docker container running ubuntu. Relevant dockerfile: https://github.com/rickbassham/indi-qt-test/blob/main/.devcontainer/Dockerfile

Hello everyone!

I think it's a function missing in the compiled library that the Meta-Object Compiler creates.

There are two solutions, compiling the library with MOC, or adding header files to the final project.

1. In the first case, I can post a pull request and make it available for testing - @knro decision.

2. The second solution is to add a path with a header like below. Sorry for the direct file path - I'm just showing where the problem is

add_executable(${PROJECT_NAME} main.cpp client.cpp /usr/include/libindi/baseclientqt.h)

@pawel-soja Thank you. Go ahead with the MOC PR, I take this for granted in KStars I forgot about it here!

What's left to do here ?
