Gamepad loading errors on some Unix distributions

[BenCheung0422]

The following errors occur when I have installed such Unix distributions (amd64) with mostly default configurations. Tests are conducted with the latest 2.2.0-dev5. Screenshots are used because it is difficult to capture the texts directly.

• CentOS 7 (Core): Obviously there is something wrong with the SDL2 library in the system.
• FreeBSD 14 (14.0-RELEASE-p4): It seems like the Java library cannot correctly detect SDL2 libraries. Note that there was a similar problem in JNA but solved afterwards: https://github.com/java-native-access/jna/issues/302.

Tested distributions without this problem:

• Ubuntu 22.04
• Debian 11/12
• Fedora Workstation 39 (bundled JDK is missing AWT; a separated installation of JRE is required)

Distributions to be tested:

• ArchLinux
• Linux Mint
• OpenSUSE
• Manjaro
• Elementary
• Zorin

Follow-up actions are required for this bug. Probably some distributions require special countermeasures. This report will be updated for any later changes.

For the platform support regarding Unix and Unix-like operating systems, it should be set to only MacOS and Linux.

For the version support regarding GLIBC 2.27 (Linux), different platforms have different version supports, then these are the minimum requirements about the OS versions (data from websites):

• Arch Linux 4.16.12
• CentOS 8
• Ubuntu 18.04
• Debian 10
• Fedora 28
• Linux Mint 19

However, it is suggested to skip gamepad loading when it is not supported, as the gamepad function is not necessary in game.

Furthermore, as the controller support is based on SDL2, so the corresponding hardware prerequisites would depend on it.
