Add Fedora 32 instructions and use the dev packages to avoid compilin… #43

Closed DaveWK closed 3 years ago

DaveWK commented 4 years ago

note: I know this one is up: https://github.com/CatxFish/obs-v4l2sink/pull/33 but I think i was able to trim down the build time considerably by reworking the cmake a bit..

…g obs-studio

There's a lot of deps I seemed to be mising to compile obs-studio

Interstingly the "dev" package for Fedora does contain the ObsPluginHelpers.cmake however the Ubuntu one does not

I noticed the config cmake for libObs seemed to have any values or things you'd need out of it so the "include dir" statement isn't needed

You can still pass in a var to get the old behaviour and leverage any possibly shared libs like ffmped with the LIBOBS_CMAKE_MODULES var

I was able to successfuly get this working with Fedora 32

on my Debian system, I get

-- Detecting CXX compile features - done
-- Found Libobs: /usr/lib/x86_64-linux-gnu/libobs.so  
CMake Error at external/FindLibObs.cmake:76 (include):
  include could not find load file:

@lukester1975 gave steps to build on Fedora 32 without the need of a PR:

(Reposted/deleted from other thread) I think those instrructions are using dependencies off the system without specifying them for obs-studio, which additionally was why I wanted to not compile obs-studio to build the plugin, as it adds extra packages and steps to make it. if I install the bin for obs-studio from a package manager I dont need to install as many deps or wait for obs-studio to compile just to get the static libs.

@raylu -- are you sure you installed libobs-dev? I think this is the right place for debian and ubuntu? https://packages.ubuntu.com/bionic/amd64/libobs-dev/filelist

DaveWK commented 4 years ago

Added some dockerfiles to prove that it's working on both debian and fedora now; there is an odd bug in obs-studio's packaging where the ubuntu/debian version doesn't contain obs-frontend-api.h (but the Fedora package does) -- a fix was merged a few days ago: https://github.com/obsproject/obs-studio/pull/2635

I am not super familiar with if there's some trickery that I can do to make cmake use relative paths for the install makefile, but it's almost at the point where it seems like using CPack and making an rpm/deb might be a simpler solution to package it all in a docker container..
