Hi, I am attempting to create Linux “Bookworm” docker container with the compiled Solar2D run-times so that I can use Solar2D to make on-screen training sequences for medical instruments, even use it to display results emerging from a patients vital signs. This top layer would be pure LUA. Hardware abstraction layers and middleware written in C++, may even use RTOS. The idea fits with the idea of making open source medical instrumentation and research instruments. So far I have made a container with all the dependencies needed to cross-compile the Solar2D so it can run on an multi-core Arm64 board running Linux Bookworm. Fairly painful work, but worthwhile to escape the clutches of Qt.

Sitrep: the docker container for building solar2D on a Toradex iMX8 SOM is done.
So the GitHub - coronalabs/corona: Solar2D Game Engine main repository (ex Corona SDK) repo has “master” and “experimental” branches.
I decided I would try to build for the “master” branch.
I am noticing that there are some new files in the “experimental” branch, and that the Makefile in the master branch hiccups as they are not on “master”

So the way forward is going to have to be a fork of the repository, and make some changes !
Cheers

Sitrep: got myself a fork, cloned the repo, added my cross-compilation container and then selected the experimental branch. All the build files in the CMakelists.txt can be found I hope.

Looking promising.
make VERBOSE = 1 (close eyes and fingers crossed).
1% good, 2% good, 3% good. Its made some executables, but wait…

We don’t have a “lua_to_native_unixeol.sh” … but there is “lua_to_native.sh”.
Oooh.
Ahhh here we are…!

Right.
/platform/linux/lua_to_native.sh
was superseded by
/platform/linux/lua_to_native_unixeol.sh
But the script that is called up, does not exist. Did a search all over the repo and cannot see it. This looks like a forgot
Sit.rep: So I had a look at the CMakeLists and made a new branch of my fork, you are welcome to come over and have a look…
To access it:
HBL001/corona at linux-build (github.com)
So back to the story, I changed the CMakeLists.txt replacing the “lua_to_native_unixeol.sh” to “lua_to_native.sh”. It made a big difference.
Also I had an issue where the linker was looking in the wrong directory, so I added
set(CMAKE_BUILD_RPATH “/usr/aarch64-linux-gnu/lib”)
and now to build… Oh no, not again, more…
