GNU Info (autoconf.info)CanonicalizingGetting the Canonical System Type ================================= The following macros make the system type available to `configure' scripts. They run the shell script `config.guess' to determine any values for the host, target, and build types that they need and the user did not specify on the command line. They run `config.sub' to canonicalize any aliases the user gave. If you use these macros, you must distribute those two shell scripts along with your source code. Note: Output, for information about the `AC_CONFIG_AUX_DIR' macro which you can use to control which directory `configure' looks for those scripts in. If you do not use either of these macros, `configure' ignores any `--host', `--target', and `--build' options given to it. - Macro: AC_CANONICAL_SYSTEM Determine the system type and set output variables to the names of the canonical system types. Note: System Type Variables, for details about the variables this macro sets. - Macro: AC_CANONICAL_HOST Perform only the subset of `AC_CANONICAL_SYSTEM' relevant to the host type. This is all that is needed for programs that are not part of a compiler toolchain. - Macro: AC_VALIDATE_CACHED_SYSTEM_TUPLE (CMD) If the cache file is inconsistent with the current host, target and build system types, execute CMD or print a default error message. automatically generated by info2www version 1.2.2.9 |
