Please confirm the following

  • I am using the latest stable/beta version of Fuji
  • I have confirmed that this issue is not caused by a faulty mod
  • I have searched and confirmed that this issue is not a duplicate

What were you doing?

Environment

  • OS: Arch Linux (x86_64)
  • Fuji Version: v0.7.2
  • Celeste 64: v1.1.1
  • .NET Framework: 8.0.25
  • glibc: 2.41+ (latest Arch)
  • Graphics: AMD Radeon Graphics (Mesa 26.0.3)

Issue Description

Cannot launch Celeste 64 with Fuji mod loader. The application crashes immediately on startup with a System.DllNotFoundException when trying to load /tmp/mm-exhelper.so.*.

Error Details

/tmp/mm-exhelper.so.*: cannot enable executable stack as shared object requires: Invalid argument

This appears to be a compatibility issue with:

  1. glibc 2.41+ changes in dlopen/dlmopen behavior
  2. /tmp directory mounted with noexec or kernel security restrictions
  3. MonoMod.Core's native exception helper requiring executable stack

Steps to Reproduce

  1. Install Fuji stable on Arch Linux and attempt to launch Celeste 64, application crashes immediately
  2. Install Fuji dev and situation is the same

haven't try beta yet

              • OS: Arch Linux (x86_64)
              • Fuji Version: v0.7.2
              • Celeste 64: v1.1.1

              • glibc: 2.41+ (latest Arch)
              • Graphics: AMD Radeon Graphics (Mesa 26.0.3)
              Issue Description
              Cannot launch Celeste 64 with Fuji mod loader. The application crashes immediately on startup with a System.DllNotFoundException when trying to load /tmp/mm-exhelper.so.*.
              Error Details
              /tmp/mm-exhelper.so.*: cannot enable executable stack as shared object requires: Invalid argument

              This appears to be a compatibility issue with:
              1. glibc 2.41+ changes in dlopen/dlmopen behavior
              2. /tmp directory mounted with noexec or kernel security restrictions
              3. MonoMod.Core's native exception helper requiring executable stack
              Steps to Reproduce
              1. Install Fuji stable on Arch Linux and attempt to launch Celeste 64, application crashes immediately
              2. Install Fuji dev and situation is the same
              haven't try beta yet

                          Cannot launch Celeste 64 with Fuji mod loader. The application crashes immediately on startup with a System.DllNotFoundException when trying to load /tmp/mm-exhelper.so.*.

                          1. Install Fuji stable on Arch Linux and attempt to launch Celeste 64, application crashes immediately
