Macro |
Description |
AC_MSG_CHECKING(message) |
Prints a "checking <message>" text during configure. |
AC_MSG_RESULT(value) |
Gives the result to AC_MSG_CHECKING; should specify either yes or no as value. |
AC_MSG_ERROR(message) |
Prints message as error message during configure and aborts the script. |
AC_DEFINE(name,value,description) |
Adds #define to php_config.h with the value of value and a comment that says description (this is useful for conditional compilation of your module). |
AC_ADD_INCLUDE(path) |
Adds a compiler include path; for example, used if the module needs to add search paths for header files. |
AC_ADD_LIBRARY_WITH_PATH(libraryname,librarypath) |
Specifies an additional library to link. |
AC_ARG_WITH(modulename,description,unconditionaltest,conditionaltest) |
Quite a powerful macro, adding the module with description to the configure --help output. PHP checks whether the option --with-<modulename> is given to the configure script. If so, it runs the script unconditionaltest (for example, --with-myext=yes), in which case the value of the option is contained in the variable $withval. Otherwise, it executes conditionaltest. |
PHP_EXTENSION(modulename, [shared]) |
This macro is a must to call for PHP to configure your extension. You can supply a second argument in addition to your module name, indicating whether you intend compilation as a shared module. This will result in a definition at compile time for your source as COMPILE_DL_<modulename>. |
