no1wudi opened a new pull request, #3193:
URL: https://github.com/apache/nuttx-apps/pull/3193
## Summary
• Why change is necessary: This change fixes a critical compilation error in
the ELF example. The invalid preprocessor directive # Warning would cause the
build to fail when no file system is selected in the configuration, preventing
users from building the
ELF example.
• What functional part of the code is being changed: The
examples/elf/elf_main.c file, specifically the preprocessor directive section
that handles the case when no file system is configured.
• How does the change exactly work: The change corrects the preprocessor
directive syntax from # Warning "No file system selected" to # warning "No
file system selected". The lowercase "warning" is the proper C preprocessor
directive that generates a
compiler warning, while the uppercase "Warning" is invalid syntax that
causes compilation errors.
• Related NuttX Issue reference: None specific - this is a bug fix
discovered during code review.
• Related NuttX Apps Issue/Pull Request reference: None specific - this is a
standalone fix.
## Impact
• Is new feature added? Is existing feature changed?: NO - This is purely a
bug fix that restores the intended functionality without changing any features.
• Impact on user: NO - Users will not need to adapt to any changes. In fact,
this fix improves user experience by allowing the ELF example to compile
successfully when no file system is configured.
• Impact on build: NO - The build process remains the same, but this fix
prevents build failures in specific configurations.
• Impact on hardware: NO - This change is purely in the application layer
and does not affect any hardware, architecture, or driver code.
• Impact on documentation: NO - No documentation changes are required as
this is a straightforward syntax correction.
• Impact on security: NO - This change has no security implications.
• Impact on compatibility: NO - This fix maintains backward compatibility
and does not affect interoperability.
• Anything else to consider: This fix ensures that the ELF example can be
built in configurations where no file system is selected, which is important
for testing and minimal configurations.
## Testing
I confirm that changes are verified on local setup and works as intended:
Testing logs before change:
$ make examples/elf
CC: examples/elf/elf_main.c
examples/elf/elf_main.c:316:3: error: invalid preprocessing directive
#Warning
316 | # Warning "No file system selected"
| ^~~~~~~
Testing logs after change:
$ make examples/elf
CC: examples/elf/elf_main.c
examples/elf/elf_main.c:316:3: warning: #warning "No file system selected"
316 | # warning "No file system selected"
| ^~~~~~~
