Usage of ldd-sym:
-android
search Android paths
-full
do not exit out early if all symbols are resolved (default true)
-funcs
track functions (default true)
-json
output json
-ldpath string
set LD_LIBRARY_PATH
-objects
track objects (default true)
-other
track other symbols
-path string
path to file
-profile string
path to CPU pprof file (only profiled if set)
-root string
directory to consider the root for SONAME resolution (default "/")
-std
search standard paths (default true)
-weak
get weak symbols
Basic utility to map symbol names to SONAMEs of libraries defining them.
Performs linker search path construction based on DT_RUNPATH/DT_RPATH and ld.so.conf.
Allows specifying a custom root directory; resolves all absolute and relative paths as if this directory were the root. This allows it to be used for quickly analyzing binaries in a dumped rootfs.
Support json output.
Comma-separates symbol names it encounters multiple definitions of and responds with "NO MATCHES" if no matches are found.
Example output:
$ ldd-sym -path /bin/ip
