Exporting a sketch using the Hardware I/O Library to Raspberry Pi results in broken shell script.

Created by: moritzmartingit

Description

When the exported script is executed it crashes and prints out the following error message:
"java.lang.UnsatisfiedLinkError: no processing-io in java.library.path:"

Expected Behavior

To get a working script after exporting a sketch using the Hardware I/O Library to Raspberry Pi.
The proposed change would be to include the corresponding "libprocessing-io.so" file automatically during the export.

Current Behavior

I can get the sketch running by manually copying the file "libprocessing-io.so" into the "lib" folder of the exported sketch.

Steps to Reproduce

The most simple sketch to reproduce the bug:
import processing.io.*;
GPIO.pinMode(4, GPIO.INPUT_PULLUP);

1. Export the above sketch to Linux Raspberry Pi 64 or 32 bit.
2. Execute the script in terminal.

Your Environment

• Processing version: 4.3
• Operating System and OS version (for running the exported script): Raspberry Pi 4, Raspberry Pi OS (64-bit) Published: 2023-10-10
• Other information: Problem occurs when sketch is exported on the Raspberry Pi 4 itself or as well on a MacBook Pro M2.

Possible Causes / Solutions

首先使用最小 sketch 复现 Raspberry Pi 导出，并检查生成的 shell script 及其 lib 目录。检查 Hardware I/O Library 和 libprocessing-io.so 在 32 位和 64 位导出中的处理方式；完成的标准是导出的脚本无需手动复制 native library 即可运行。
