Root cause

Gamescope prepends its payload and imagefs libraries to LD_LIBRARY_PATH. On Samsung Android 16, libgndrm_shim pulls in the system libandroid.so and then /system/lib64/libsqlite.so, but that SQLite library binds to the imagefs OpenSSL libcrypto rather than the matching system BoringSSL library. The Android linker therefore terminates Gamescope before Wine starts.

Evidence

The SM-S921B report ends at 0 seconds with:

CANNOT LINK EXECUTABLE ".../gamescope": cannot locate symbol "OpenSSL_add_all_algorithms" referenced by "/system/lib64/libsqlite.so"

No Wine process or game module is created.

Fix

In app/src/main/java/com/winlator/xenvironment/components/BionicProgramLauncherComponent.java:517, expose the matching system libcrypto through a private Gamescope library directory and prepend it to Gamescope LD_LIBRARY_PATH. This restores the compatibility handling previously added for the same Samsung dependency chain without changing Wine launches.

Verification

Static validation: git diff --check passes. Android build and device launch were not run in this support workspace.

Summary by CodeRabbit

• Improvements
  • Gamescope now uses the system’s libcrypto.so when it is available, making it accessible through Gamescope’s library search path.
  • If the system library is unavailable, Gamescope continues using its bundled libraries as before.

Walkthrough

applyGamescopeEnv now checks for /system/lib64/libcrypto.so. When present, it creates a symlink in gamescope_system_libs and prepends that directory to the Gamescope library path. Otherwise, the path remains unchanged.

Changes: Gamescope library resolution

Layer / File(s)	Summary
Add system crypto library to Gamescope path app/src/main/java/com/winlator/xenvironment/components/BionicProgramLauncherComponent.java	When /system/lib64/libcrypto.so exists, applyGamescopeEnv creates a symlink to it under gamescope_system_libs and prepends that directory to gamescopeLibPath.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to c0127

Gamescope may still fail to start on affected Samsung Android 16 devices if the crypto symlink cannot be created.

Only prepend gamescope_system_libs after the symlink succeeds.

FileUtils.symlink logs ErrnoException without returning a success status. If directory or symlink creation fails, applyGamescopeEnv still prepends the unusable directory. The loader can then select the later imagefs libcrypto.so, leaving the Samsung startup failure unresolved. Return and check the symlink result, or verify the link before updating gamescopeLibPath.
