NAME

     lorder — list dependencies for object files

SYNOPSIS

     lorder file ...

DESCRIPTION

     The lorder utility uses nm(1) to determine interdependencies in the list of object files and library
     archives specified on the command line.  The lorder utility 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.

     When linking static binaries, lorder and tsort(1) can be used to properly order library archives
     automatically.

ENVIRONMENT

     NM      Path to the nm(1) binary, defaults to “nm”.

     NMFLAGS
             Flags to pass to nm(1).

EXAMPLES

           ar cr library.a `lorder ${OBJS} | tsort`
           cc -o foo ${OBJS} `lorder ${STATIC_LIBS} | tsort`

SEE ALSO
