Linux C Standard Library Showdown: musl vs. uClibc vs. dietlibc vs. glibc
2025-05-10
An Eta Labs project compares several standard library implementations for Linux, focusing on the balance between feature richness and bloat. The article uses tables and notes to compare musl, uClibc, dietlibc, and glibc across size, performance, behavior on resource exhaustion, ABI, algorithms, features, target architectures, and build environment. musl excels in size and performance, glibc offers the most features but is the largest, while uClibc and dietlibc fall somewhere in between. The comparison also considers robustness under resource exhaustion and security implications, offering developers valuable insights for choosing the right standard library.
