…ct old way This should ensure that binaries built using this version are fixable without recompiling should issues with our current rm2fb client arise.
Sorry, but my pc has a billion toolchains and I'm not sure which one right now compiles correctly

Could you add a mention in the README about this behavior plz?

Hi, I can't get this to work as intended. Seems that libremarkable doesn't like rm2fb client. I've compile the demo and it works properly (through built-in client). But with this it doesn't work. Has anybody managed to make it work? (Software 2.15, original rm2fb from toltec, not timower) |

There was an issue raised at #117 where presumably a new library is used as a shim for rM 2 Framebuffer support, but it doesn't seem to use the offical server, which our client relies on.
In general there had been issues raised that issues could arise even with the official shim if it gets updated but our implementation still does the old behaviour. Such applications would require to be recompiled to use
Framebuffer::deviceinstead ofFramebuffer::newor otherwise not work.This PR allows people to make libremarkable choose the old implementation in case the developer didn't care about it anyway / left the choice up to libremarkable.
It is done by setting the lengthy env
LIBREMARKABLE_FB_DISFAVOR_INTERNAL_RM2FBto1,yesortrue(case-insensitive). Feel free to suggest a better name, I couldn't think of any.Package maintainers could also fix arising issues by setting that env in some wrapper script for that binary without the need of any source code change or even re-complication if the binary is recent enough.
Basically this should future proof applications built using libremarkable better.
