Crystal Palace doesn’t update properly under Linux (Mint 20.2,based on Ubuntu 20.04 LTS). The log contains the following error:

[0.161 warn src/plugin.cpp:203 loadPlugin] Could not load plugin /home/darchillus/.Rack2/plugins/CrystalPalace: Failed to load library /home/darchillus/.Rack2/plugins/CrystalPalace/plugin.so: /lib/x86_64-linux-gnu/libc.so.6: version ``GLIBC_2.32' not found (required by /home/darchillus/.Rack2/plugins/CrystalPalace/plugin.so)

Looks like the plugin has been build using a too recent version of GLIBC, making it incompatible with Linux distributions that are slightly older (but still used a lot). We’ve seen the same problem with the Blamsoft XFX plugins (see Blamsoft is back thread).

Yup, like I said over here:

Rack development blog

As some of you know, in order to produce a Linux plugin build that works on all Linux distros supported by Rack, you must compile against glibc 2.23 and libstdc++ 5.4.0, which is what Ubuntu 16.04 uses. This is because the ABIs of the GNU implementations of the C and C++ standard library change every few years. Previously the only way to correctly do this is to use Ubuntu 16.04 (and thus an old version of GCC) for building plugins, either in a virtual machine, Docker container, or installed on …

This REALLY should be better documented in the developer manual.
