Questions tagged [eglibc]

Embedded GLIBC (EGLIBC) was a variant of the GNU C Library (GLIBC) that was designed to work well on embedded systems. EGLIBC strived to be source and binary compatible with GLIBC. EGLIBC's goals included reduced footprint, configurable components, better support for cross-compilation and cross-testing. EGLIBC is no longer developed and such goals are now being addressed directly in GLIBC.
