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). 17AC_DEFUN([AM_PROG_INSTALL_STRIP], 18[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl 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. 23dnl Don't test for $cross_compiling = yes, because it might be 'maybe'. 24if test "$cross_compiling" != no; then 25 AC_CHECK_TOOL([STRIP], [strip], :) 26fi 27INSTALL_STRIP_PROGRAM="\$(install_sh) -c -s" 28AC_SUBST([INSTALL_STRIP_PROGRAM])]) 29
