Cannot build with custom libobs (missing files in the OBS.app) in Mac

[jamesguitar3]

System: macOS 13.3.1 (arm64) obs-studio: v28.0.3

I followed the instructions in README to build using a custom libobs, and had set ENABLE_UI=false when built obs-studio as told in README. (The generated libobs package is much smaller with this ENABLE_UI=false setting)

So when building obs-studio-node by running the /ci/build-osn-osx.sh, I ran into the following error and of course the files are indeed missing tin the package.

Make Error at obs-studio-server/cmake_install.cmake:121 (file):
  file INSTALL cannot find
  "/Users/james/Projects/streamlab/obs-studio-node/build/libobs-src/OBS.app/Contents/MacOS":
  No such file or directory.
Call Stack (most recent call first):
  cmake_install.cmake:46 (include)

Any idea how to build this using the custom libobs? Thx

Readme file probably are outdated.

You will get better results when using same build scripts what CI machines use. https://github.com/stream-labs/obs-studio/blob/f254c4d0a11e8647cf9ba73b96f853d066a81102/.github/workflows/main-streamlabs.yml#LL74C6-L74C6

You will need to set variables and start this script ./slobs_CI/build-script-osx.sh

Hi @summeroff thanks for commenting. I did build the libobs by running the ./slobs_CI/build-script-osx.sh script. However, I thought I had to add the DENABLE_UI=false in the script in order to use this custom libobs to build obs-studio-node. Here is what it says in the osn README:

Custom OBS Build
By default, we download a pre-built version of libobs if none is specified. However, this pre-built version may not be what you want to use or maybe you're testing a new obs feature.

You may specify a custom archive of your own. However, some changes need to be made to obs-studio's default configuration before building:

ENABLE_SCRIPTING must be set to false
ENABLE_UI must be set to false
QTDIR should not be specified as it is not used.

Any ideas?

Yes this part of a readme is outdated. it was not updated when macos support was added.

@summeroff Thanks for posting the env vars for the script. I basically built using very similar env values. I guess the DENABLE-UI=false is not required when building obs-studio for custom libobs used in osn then, or at least not required for mac?
