Java: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

Question

I've been working on a Java project that uses a gui.jar file to import some classes. Everything was working fine until yesterday. Now, I can compile the .class files by the command

javac -d ./bin -sourcepath ./src -classpath ./bin/gui.jar src/simulation/TestSimulateur.javac

but when I try to execute the program with

java -classpath bin:bin/gui.jar simulation.TestSimulateur

I get the error

java: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE make: *** [Makefile:47: carte1] Error 127

I don't know much about how snap and the libraries work so I'm not sure about the root of the problem. It's strange that the problem only appears when I run it on VSCode, while it works fine if I run it on the normal Linux terminal.

I've searched a lot but couldn't find how to solve the problem. As I've said, I'm newbie on Linux system. Between my attempts, I tried to reinstall VSCode, updating the system and updating snap packages, but none of those worked.

Answer 1

Though I have already answered it here

The issue with how the VSCode Snap package libraries are configured to be used. They are setting the following environment variable GTK_PATH, which gets inherited by the VSCode Terminal.

Unsetting the environment variable in the VSCode terminal does seem to work for me.

unset GTK_PATH

As a slightly more permanent workaround, you can also unset GTK_PATH in your VS Code user settings, run "Preferences: Open User Settings (JSON)" and add this to your settings.json:

    "terminal.integrated.env.linux": {
        "GTK_PATH": ""
    }

Update 2: 2024-03-09

It seems the VSCode Snap package(version 1.87.1) has introduced even more environment variables for GTK Toolkit.

I have to additionally unset the following environment variables for additional GTK Built Applications:

unset GIO_MODULE_DIR

For people looking at solving this issue with the VSCode Snap Package installation can use the following in their settings.json:

"terminal.integrated.env.linux": {
    "GTK_PATH": null,
    "GIO_MODULE_DIR": null,
},
