#

I need to LD_PRELOAD (linux thing) some libraries into Celeste, but the launcher is trolling, it seems according to htop it forks or something and drops the environment variable. When I cat /proc/<pid>/environ I can see that one the processes do not have the env variable set, and that seems to be the game because I setup a message to print when it initalizes or one of the modified funcs is run but none of them are triggering.

#

./run.sh ~/Downloads/Master/Celeste.bin.x86_64 is how it gets run so no I'm bypassing the arch selecting bash script altogether

are you using the steam version of the game?

oblique wraith May 20, 2023, 4:29 AM

#

itch.io patched with everest so no steam wrapper

#

I did patch it from another computer and copy it over to this system because I wanted to a consistent experience

you should put anything that you want to always get ran before starting the game in Celeste shell script thats included on all linux versions of celeste

well my launcher script does pretty much the same as the one that comes with celeste which is running./Celeste.bin.x86_64 idk why they support macos in the linux build :/

#!/bin/bash
# Celeste Shell Script
# Written by Ethan "flibitijibibo" Lee

# Move to script's directory
cd "`dirname "$0"`"

# Get the system architecture
UNAME=`uname`
ARCH=`uname -m`

# MonoKickstart picks the right libfolder, so just execute the right binary.
if [ "$UNAME" == "Darwin" ]; then
    # ... Except on OSX.
    export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:./osx/

    # El Capitan is a total idiot and wipes this variable out, making the
    # Steam overlay disappear. This sidesteps "System Integrity Protection"
    # and resets the variable with Valve's own variable (they provided this
    # fix by the way, thanks Valve!). Note that you will need to update your
    # launch configuration to the script location, NOT just the app location
    # (i.e. Kick.app/Contents/MacOS/Kick, not just Kick.app).
    # -flibit
    if [ "$STEAM_DYLD_INSERT_LIBRARIES" != "" ] && [ "$DYLD_INSERT_LIBRARIES" == "" ]; then
        export DYLD_INSERT_LIBRARIES="$STEAM_DYLD_INSERT_LIBRARIES"
    fi

    ./Celeste.bin.osx $@
else
    if [ "$ARCH" == "x86_64" ]; then
        ./Celeste.bin.x86_64 $@
    else
        ./Celeste.bin.x86 $@
    fi
fi

ah I think it's a quirk of monokickstart and i'll have to figure out how it works

i was able to ld_preload custom libs to celeste with everest a while ago, unless you're doing something really weird a custom launch script shouldn't mess things up

did you have one of the drm free versions (nonsteam)

oblique wraith May 21, 2023, 6:29 AM

#

oblique wraith I need to `LD_PRELOAD` (linux thing) some libraries into Celeste, but the launch...

this is pretty much the launch script

cunning rock May 21, 2023, 8:16 AM

#

oblique wraith did you have one of the drm free versions (nonsteam)

yes, i specifically did it on the itch.io version

oblique wraith May 21, 2023, 5:34 PM

#

actually I highly suspect the current working directory is not the same and it's noticing that and respawning itself maybe

cunning rock May 21, 2023, 5:38 PM

#

what, that would be hella weird

#

this is here for a reason

oblique wraith May 21, 2023, 6:01 PM

#

well I was bypassing the script whoops because I didn't want to be ld_preloading the shell script but actually that might not be an issue so I'll try that
