20 people shuold be ok in the switch... although raspberry pi 4 ,4g ram model shuold act similarly..

 

I'm trying to make LWJGL3 work but's constantly crashing in newer minecraft versions. I'll see if I can make it work and run somehow.

 

Anyone know what this error means?

Picked up _JAVA_OPTIONS: -Djava.library.path=/home/jacob/.minecraft/natives/
OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.lwjgl.DefaultSysImplementation.getPointerSize()I

I got the MultiMC launcher to work. This is mostly pulled from the MultiMC build documentation. To build it run:

Code:

git clone (MultiMC5 git repo on github I cant post links)
cd MultiMC5
git submodule init
git submodule update
sudo apt install gcc qt5-default cmake zlib1g-dev openjdk-8-jdk libgl1-mesa-dev
mkdir build
mkdir install
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ..
make -j4 install

To run MultiMC:

Code:

cd ../install
./MultiMC

To run Minecraft in MultiMC it does not accept the java libraries path argument (it just ignores it) but if you stop the java process immediately and replace the natives in the instance dir/natives, and then resume the java process it will launch. I created a set of python scripts to do this automatically, but they wont work if other java programs are running, and will crash if the instance is running for the first time, because the first time you launch a MultiMC instance it create a file that it need to read to find the lwjgl version. Just add:

Code:

python3 WHEREVER_THE_SCRIPTS_ARE/copynativeslauncher.py $INST_DIR

to the custom commands Pre-launch command and it will run on launch. In the folder with the scripts there is a conf.json file to specify the lwjgl paths. If you are only planning on using one lwjgl version, you can remove the other one leave it as the default or blank.

Also if anyone knows how to fix the lwjgl3 error:

Code:

[Client thread/INFO]: [STDERR]: [LWJGL] [ERROR] Incompatible Java and native library versions detected.
Possible reasons:
   a) -Djava.library.path is set to a folder containing shared libraries of an older LWJGL version.
   b) The classpath contains jar files of an older LWJGL version.
Possible solutions:
   a) Make sure to not set -Djava.library.path (it is not needed for developing with LWJGL 3) or make
      sure the folder it points to contains the shared libraries of the correct LWJGL version.
   b) Check the classpath and make sure to only have jar files of the same LWJGL version in it.

For using controllers in Minecraft you can use QJoyPad. To install it:

Code:

sudo apt install qjoypad

And to run it:

Code:

qjoypad --notray

 

@Canberk @ShinkoNet anyone manage to get liblwjgl to work with optifine 1.14.3, mine crashes a second after the game launches with this error

i cannot for the life of me figure out how @Canberk got his game to load

 

can someone make an video tutorial to how to do it?

 

sorry I missed all the messages, I didn't get notified for some reason. I ended up deleting L4T in favor of Android but I still have some things that may be of help. one thing you'll want to keep in mind is that these files must replace the files in OP, not be alongside them. your natives folder must only have what I have in the archive above. I made numerous changes in lwjgl3's source and built it straight from the Switch in order to get what is in the above archive. I wish I remembered what changes I made (or I backed it up before wiping L4T away), but this is sadly all the information I have.

I used this bash script to launch Minecraft 1.14.3 (afaik, also try 1.14.2 to be safe) and I have noticed that it does NOT work with any later version. put the Minecraft launcher inside ~/minecraft.jar (~ represents your home directory), copy the script that starts with "#!/bin/bash" (it is the entirety of the three lines which go to the end of the post) into a file with the ".sh" extension, and open a terminal. type "chmod +x " into the terminal (with the space at the end) and drag this script into your terminal window. now you may be able to double-click the script (or drag it to the terminal window without anything typed in it) to launch Minecraft!

I got a ton of "Incompatible Java and native library versions detected" from lwjgl but I merely ignored them and the game played perfectly fine.

I don't know what sort of problems you guys are having with Optifine as I had it working perfectly fine (in fact, I even tried my roommate's Switch to make sure!). Please let me know if you still have trouble and I'll try to help as much as I can!

Running into this same issue but don’t know how to fix it without reinstalling Linux

Edit: I found a solution! I actually add to do “sudo apt purge “program”” for the ones that I installed during this tutorial, I then had to do “sudo rm /usr/lib/libjawt.so” and redid the tutorial and now it works perfectly.

 

The majority of my changes were changing amd64 to arm64 (or aarch64, I can't remember). I remember running ack (basically recursive grep) to find all references to x86 and amd64 which I would end up changing to arm64 (or aarch64). I may have also had to make a few other changes, it took a good few days to figure it all out and it's sadly really not fresh in my memory. Such a shame I forgot to back the source up...

I am completely baffled that it just doesn't work for you guys, I'll take a look at what I did and compare it to OP. I tested it on two switches before I posted my files...

EDIT: I went back to my roommate's switch which thankfully still had L4T installed. Turns out I'm an idiot. I used OpenJDK 11 instead of 8 on both my test switches, that's why it works for me and not you guys. Perhaps try again after running "sudo apt purge openjdk-8-jdk && sudo apt install openjdk-11-jdk" in your terminal, without the quotes? I also don't see /usr/lib/libjawt.so as OP suggests so experiment both with and without the file being present. Just don't forget that the symlink will likely break after running the above command so you may find it beneficial to remove and re-link it.

 

I just told the solution for my Edit... All I did was remove the programs that I installed during this tutorial using the "sudo apt purge (insert program name)", then I did "sudo rm /usr/lib/libjawt.so" and I started the tutorial from the beginning.
