This is needed to be able to run check-links.sh against a "sysrooted" binary while ensuring that the ldd(1) call done on the host uses the host libc. It is not possible to set LD_LIBRARY_PATH before calling check-links.sh as then the "sysrooted" libc would be incorrectly used. A LD_PRELOAD=libc.so is used to ldd(1) as it needs to use the host libc to run. ldd(1) is a simple wrapper around execve(2) and dlopen(2) with env LD_TRACE_LOADED_OBJECTS set. Due to the dlopen(2) restriction on shared library tracing ldd(1) is still required for this lookup. Sponsored by: EMC / Isilon Storage Division |
