D. Ferrocene Self-test Error Codes

D.1. FST_001: No sysroot

This error occurs when the ferrocene-self-test binary has not been installed in the bin folder within the Ferrocene toolchain installation directory, aka “the sysroot”.

Suggested fixes

If you have moved the ferrocene-self-test binary out of the sysroot, move it back into that directory.

Alternatively, reinstall the Ferrocene toolchain.

D.2. FST_002: Missing binary

This error occurs when one of the Ferrocene toolchain binaries has not been installed.

Suggested fixes

Ensure that all packages of the Ferrocene toolchain have been properly installed.

D.3. FST_003: Wrong binary permissions

This error occurs when a Ferrocene toolchain binary lacks execution permissions.

Suggested fixes

Grant execution permission to the indicated Ferrocene toolchain binary.

D.4. FST_004: Metadata fetch failed

This error occurs when a Ferrocene toolchain binary is not accessible.

Suggested fixes

Ensure that file ownership and system permissions are correctly set.

D.5. FST_005: Version fetch failed

This error occurs when the invocation of rustc failed.

Suggested fixes

Reinstall the Ferrocene toolchain.

D.6. FST_006: Version parse failed

This error occurs when the version of rustc cannot be parsed.

Suggested fixes

Ensure that another binary with the same name has not been installed in the sysroot.

D.7. FST_007: Binary version mismatch

This error occurs when the version of the ferrocene-self-test binary and that of rustc are not the same.

Suggested fixes

Do not use the same ferrocene-self-test binary with different Ferrocene toolchains.

Reinstall the Ferrocene toolchain in order to obtain the expected ferrocene-self-test or rustc binary.

D.8. FST_008: Missing target library

This error occurs when the installation of the Ferrocene toolchain for a particular target is malformed.

Suggested fixes

Reinstall the Ferrocene toolchain.

D.9. FST_009: Duplicate target library

This error occurs when two versions of the Ferrocene toolchain were installed on top of each other.

Suggested fixes

Ensure that the sysroots of both installations are distinct.

D.10. FST_010: Target library discovery failed

This error occurs when a Ferrocene toolchain library is not accessible.

Suggested fixes

Ensure that file ownership and system permissions are correctly set.

D.11. FST_015: Bundled linker missing

This error occurs when the Ferrocene toolchain linker is not available.

Suggested fixes

Ensure that the Ferrocene toolchain has been properly installed.

D.12. FLS_016: Path not in UTF-8

This error occurs when the Ferrocene self-test tool attempts to access a path that is not in UTF-8.

Suggested fixes

Ensure that sysroot of the Ferrocene toolchain is a valid UTF-8 path.

D.13. FLS_017: Creation of temporary directory failed

This error occurs when the Ferrocene self-test tool cannot create a temporary directory where it will compile and run sample test programs.

Suggested fixes

Ensure that file ownership and system permissions are correctly set.

D.14. FLS_018: Test program cannot be created

This error occurs when the Ferrocene self-test tool cannot create the source file of a test program.

Suggested fixes

Ensure that file ownership and system permissions are correctly set.

Ensure that there is enough free disk space.

D.15. FLS_019: Test program cannot be compiled

This error occurs when the Ferrocene self-test tool cannot compile a test program.

Suggested fixes

Ensure that the operating system is supported by the Ferrocene toolchain.

Ensure that the prerequisites of the Ferrocene toolchain has been properly installed.

Ensure that the Ferrocene toolchain has been properly installed.

D.16. FLS_020: Compilation artifact cannot be read

This error occurs when the Ferrocene self-test tool cannot read an artifact produced by compiling a test program.

Suggested fixes

Ensure that file ownership and system permissions are correctly set.

D.17. FLS_021: Missing compilation artifact

This error occurs when the Ferrocene self-test tool cannot find an expected artifact produced by compiling a test program.

Suggested fixes

Ensure that the Ferrocene sysroot is not tampered with while the self-test tool is running.

Ensure that the Ferrocene toolchain has been properly installed.

D.18. FLS_022: Unexpected compilation artifact

This error occurs when the Ferrocene self-test tool finds an additional unexpected artifact produced by compiling a test program.

Suggested fixes

Ensure that the Ferrocene sysroot is not tampered with while the self-test tool is running.

Ensure that the Ferrocene toolchain has been properly installed.

D.19. FLS_023: Suitable C Compiler not found

This error occurs when the Ferrocene self-test tool is unable to find a C compiler which meets the requirements for a specific target.

Suggested fixes

Install a suitable C compiler for that target, such as GCC or clang.

D.20. FLS_024: Linker Arguments error

This error occurs when the Ferrocene self-test tool is unable to find a C compiler which emits only valid linker arguments to the linker.

Suggested fixes

Install a suitable C compiler for that target, such as GCC or clang.
