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 . |
