Normally, running an ELF against a different glibc, you'd use LD_LIBRARY_PATH and patchelf, or use chroot/docker.
chlibc allows you to change the dynamic linker of a process on the fly without patching and root access.
Key Features:
- zero disk modification: no need for patchelf --set-interpreter. - no root required: works entirely in user-space via ptrace - multi-arch: native support for x86_64, AArch64, and RISC-V. - lightweight: unlike PRoot, which intercepts every syscall to translate paths, chlibc only intervenes during the initial execve() phase. Once the loader is swapped, it almost has no runtime overhead.
I’d love to hear your thoughts about this tool, thanks!
