# 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
|
