Okay, I need to classify this bug report for QEMU. The user provided an error message when compiling from source on macOS: "found no usable tomli, please install it." So first, I'll break down what's happening here. The error is about the 'tomli' module not being found during compilation. Tomli is a Python library used for parsing TOML configuration files. QEMU might be using this library as part of its build process or dependencies. Now, looking at the possible categories: mistranslation, assembly lowering, and others like device, network, kernel, etc. I need to see which category fits best. Mistranslation usually refers to issues in converting source code to IR or target architecture, often happening in user-mode. This doesn't seem related since the error is about a missing Python module during compilation. Assembly lowering is about translating high-level code to assembly, which also doesn't apply here because the issue isn't with the assembly process but rather a missing dependency. The other category covers things that don't fit into specific areas like device or network. Since this is about a build-time dependency issue, it's more related to the build process and not any specific component of QEMU. I think 'other' is the most appropriate because it's a build dependency error rather than an issue with the target architecture translation, assembly, or specific features like network or graphics. other
