  20 # Usage:
  21 #   install-reloc library_path_var library_path_value prefix compile_command srcdir config_h_dir install_command... destprog
  22 # where
  23 #   - library_path_var is the platform dependent runtime library path variable
  24 #   - library_path_value is a colon separated list of directories that contain
  25 #     the libraries at installation time (use this instead of -rpath)
  26 #   - prefix is the base directory at installation time
  27 #   - compile_command is a C compiler compilation and linking command
  28 #   - srcdir is the directory where to find relocwrapper.c and its dependencies
  29 #   - builddir is the directory where to find built dependencies (namely,
  30 #     alloca.h and stdbool.h)
  31 #   - config_h_dir is the directory where to find config.h
  32 #   - install-command is the install command line, excluding the final destprog
  33 #   - destprog is the destination program name
  34 # install-reloc renames destprog to destprog.bin and installs a relocating
  35 # wrapper in the place of destprog.
