Ubuntu Focal build container with HTML5 VNC interface and QtCreator (#343)

The external dependencies are now built and installed.
But when I run cmake in QtCreator for ksnip I get an error:

-- XCB: XFIXES requires XCB;RENDER;SHAPE

CMake Error at src/CMakeLists.txt:152 (add_executable):
  Target "ksnip" links to target "XCB::XFIXES" but the target was not found.
  Perhaps a find_package() call is missing for an IMPORTED target, or an
  ALIAS target is missing?

Can you make anything out of it? Several xcb packages are installed.

I found the missing packages.

ksnip builds now in QtCreator inside the Docker container 🥳

I wanted to map the ksnip source code directory in the Docker container to the local ksnip directory in 4e6dd97, but that has the disadvantage that the new owner will be root.

Using an unprivileged user in the Docker container had the disadvantage that its home directory isn't yet available in the Dockerfile. 😬

[pbek]

I found a way around that. 👍
The ksnip source code directory in the Docker container is now mapped to the local ksnip directory. 😁 Works great unless your local user has another UID than 1000.

You could now test the container yourself if you like.

It fails to run the build script:

Under OpenSUSE I need to run docker with sudo, could it be related to that?

Very strange, the file is there, I'm in the correct directory, I'm root, the file has the execute bit but still is says "file not found".

Maybe you need to do a sudo docker-compose build.

[DamirPorobic]

Nah, it's not that, looks like something wrong with the fileformat of the script. I've started the container and tried to run the script from there and got this error:
/bin/sh^M : bad interpreter

After fixing the file like described here in the solution it worked from the container. Now I'm trying to build again after I've fixed the file in the repo.

[DamirPorobic]

Didn't work and now the container is also not coming up, running build or up results in same behavior or console output. Need to restart I guess.

[pbek]

Strange, never saw that issue before. Meanwhile I pushed a version to https://hub.docker.com/r/pbeke/ksnip-desktop.

[DamirPorobic]

Thanks a lot :)

I'll try to fix the script tomorrow.

[pbek]

If you want to test the pre-built container 😁

docker-compose up ksnip-desktop-pre-built

[pbek]

Nice, I'm able to run the ksnip binary, built inside the container outside of the container.
