| # Usage 1: |
| # install-reloc -- library_path_var library_path_value prefix destdir \ |
| # compile_command srcdir builddir config_h_dir exeext \ |
| # strip_command \ |
| # install_command... destprog |
| # where |
| # - library_path_var is the platform dependent runtime library path variable |
| # - library_path_value is a colon separated list of directories that contain |
| # the libraries at installation time (use this instead of -rpath) |
| # - prefix is the base directory at installation time |
| # - destdir is a string that is prepended to all file names at installation |
| # time; it is already prepended to destprog but not to library_path_value |
| # and prefix |
| # - compile_command is a C compiler compilation and linking command |
| # - srcdir is the directory where to find relocwrapper.c and its dependencies |
| # - builddir is the directory where to find built dependencies (namely, |
| # alloca.h and stdbool.h) |
| # - config_h_dir is the directory where to find config.h |
| # - exeext is platform dependent suffix of executables |
| # - strip_command is the command for stripping executables, or : if no |
| # stripping is desired |
| # - install_command is the install command line, excluding the final destprog |
| # - destprog is the destination program name |
| # Usage 2: |

| # install-reloc prog1 ... destprog |
| # where destprog is either the destination program name (when only one program |
| # is specified) or the destination directory for all programs. |
| # install-reloc renames destprog to destprog.bin and installs a relocating |
| # wrapper in the place of destprog. |
