# 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 |
|

# RELOC_INSTALL_PROG=install_command... \ |
|
# 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. |
