LORDER(1) General Commands Manual LORDER(1)

list dependencies for object files

lorder file ...

The lorder utility uses nm(1) to determine interdependencies in the list of object files specified on the command line. lorder outputs a list of file names where the first file contains a symbol which is defined by the second file.
The output is normally used with tsort(1) when a library is created to determine the optimum ordering of the object modules so that all references may be resolved in a single pass of the loader.

Path to nm(1) executable to use. Defaults to ‘nm’.
