Worked on the YosysHQ/yosys repository to improve build reliability by addressing a bug in the Makefile related to resource accessibility. Focused on the build system, the developer corrected the process for copying the share directory, ensuring that files are placed directly into the target Python directory rather than within an unnecessary nested subdirectory. This adjustment resolved path-related build failures and made share files accessible at the expected location, reducing potential issues during packaging and runtime. The work primarily involved Makefile scripting and build system management, demonstrating attention to detail in maintaining robust and predictable build processes for the project.
