| # AM_PROG_INSTALL_STRIP |
| # --------------------- |
| # One issue with vendor 'install' (even GNU) is that you can't |
| # specify the program used to strip binaries. This is especially |
| # annoying in cross-compiling environments, where the build's strip |
| # is unlikely to handle the host's binaries. |
| # Fortunately install-sh will honor a STRIPPROG variable, so we |
| # always use install-sh in "make install-strip", and initialize |
| # STRIPPROG with the value of the STRIP variable (set by the user). |
| AC_DEFUN([AM_PROG_INSTALL_STRIP], |
| [AC_REQUIRE([AM_PROG_INSTALL_SH])dnl |
| # Installed binaries are usually stripped using 'strip' when the user |
| # run "make install-strip". However 'strip' might not be the right |
| # tool to use in cross-compilation environments, therefore Automake |
| # will honor the 'STRIP' environment variable to overrule this program. |
