! 23: # install_command... destprog
1.1 misho 24: # where
25: # - library_path_var is the platform dependent runtime library path variable
26: # - library_path_value is a colon separated list of directories that contain
27: # the libraries at installation time (use this instead of -rpath)
28: # - prefix is the base directory at installation time
29: # - destdir is a string that is prepended to all file names at installation
30: # time; it is already prepended to destprog but not to library_path_value
31: # and prefix
32: # - compile_command is a C compiler compilation and linking command
33: # - srcdir is the directory where to find relocwrapper.c and its dependencies
34: # - builddir is the directory where to find built dependencies (namely,
35: # alloca.h and stdbool.h)
36: # - config_h_dir is the directory where to find config.h
37: # - exeext is platform dependent suffix of executables
38: # - strip_command is the command for stripping executables, or : if no
39: # stripping is desired
40: # - install_command is the install command line, excluding the final destprog
41: # - destprog is the destination program name
