Can't build

[arjpar]

After following the instructions in build.md and running the build script, I can't seem to build Plato, since libev-dev isn't found, despite the fact that I have it installed (libev). Thus, cross-compilation doesn't work. I tried building it using Docker, but that doesn't work too due to platform config for Docker (building it using the right platform target). I think I'm doing something wrong but I'm not sure.

error: failed to run custom build command for `evdev-sys v0.2.5`

[randomnoise]

First line of stderr might be relevant: fatal: not a git repository (or any of the parent directories): .git

Did you clone the repository with git or just download the zip file and extract? If that is an issue, a change in build.md would be useful.

Also, not revelant to your issue but did you rename the project's folder as aristotle on your computer? 😂

[arjpar]

@randomnoise I managed to fix that issue, but it still doesn't build because ev-dev isn't found despite the fact that I installed it. I checked (did some google searches) and apparently it seems like the build process won't work for macOS because it requires some Linux specific things? I dunno, it's been a few weeks so it's IIRC. I tried building it with docker, and it still doesn't work. I really don't know what to do.

[randomnoise]

I've tried building Plato using Docker for different reasons. (I did not want to install MuPDF dependencies on my local machine) It was successful for me and ev-dev was not an issue.

You can look into builder.Dockerfile on https://github.com/randomnoise/plato-in-container

I hope it helps.

[arjpar]

@randomnoise I tried building it using that repository and its Dockerfiles (with my minor modifications to make it work), and it still didn't work. It didn't work with no modifications either despite setting it up correctly. The problem is still with mupdf-sys .

[randomnoise]

@arjpar, at first glance, I can see that you are not trying to build Plato. Instead, you are trying to build your own fork.

Unfortunately, the name and the description of this issue is misleading.

I think you should go incrementally; build the vanilla Plato, then you should try to compile your changes.

You are also trying to use mupdf-sys crate and it seems it can't compile targeting arm-linux-gnueabihf architecture. It is better to track this issue in the crate's repo.

Also, integration between MuPDF and Plato can be brittle. A specific MuPDF version (1.23.11 at the moment) is used and then Kobo specific patches are applied to it. Even, getting Plato to work with MuPDF's Debian packages can cause issues. (believe me, I've tried to use them) So, reading lots of logs and debugging are your friend here.

Good luck with your changes 🤘
