8 # AM_PROG_INSTALL_STRIP
9 # ---------------------
10 # One issue with vendor 'install' (even GNU) is that you can't
11 # specify the program used to strip binaries. This is especially
12 # annoying in cross-compiling environments, where the build's strip
13 # is unlikely to handle the host's binaries.
14 # Fortunately install-sh will honor a STRIPPROG variable, so we
15 # always use install-sh in "make install-strip", and initialize
16 # STRIPPROG with the value of the STRIP variable (set by the user).

19 # Installed binaries are usually stripped using 'strip' when the user
20 # run "make install-strip". However 'strip' might not be the right
21 # tool to use in cross-compilation environments, therefore Automake
22 # will honor the 'STRIP' environment variable to overrule this program.
