Letâs postpone issue 3 for the time being. After I know that CEF stands for âChromium Embedded Frameworkâ, I am going to look into that later. Maybe Gentoo has already a package for that. I am going to check that out.
I have been able to fix the compilation errors by applying to patch files locally. One of them is the fix: boost 1.85/1.86 (#1584). Thank you for the pointer. The other patch is even more trivial, it only adds some missing headers to the appropriate source files.
Patch which adds one missing header to each out of four source files

So, compilation phase succeeds now, but linking phase fails. I paste the entire error here, maybe someone can make some sense out of it

ninja: build stopped: subcommand failed.
As far as I understand it, the Ninja build system calls the script src/shell/run.sh. However, I cannot make any sense out of this script. It tries to repeatedly rung the command bin/casparcg until the return value does not equal 5. That sounds odd.
But maybe the script isnât the problem and the linking error is caused by something different.
