Makefile:138: recipe for target 'all' failed make: *** [all] Error 2

This error message indicates that the "all" target in the Makefile failed to build. There could be a number of reasons for this, including missing dependencies, syntax errors in the Makefile, or issues with the build environment. To diagnose the problem, you should review the Makefile and any associated build scripts to ensure that they are properly configured and that all necessary dependencies are present. You may also need to consult the documentation for any external libraries or tools that are being used in the build process. If you are still unable to resolve the issue, you may need to seek assistance from the community or the maintainers of the software you are attempting to build.
