dnl config.m4 for extension sdl_ttf
dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary.
dnl If your extension references something external, use 'with':
dnl PHP_ARG_WITH([sdl_ttf],
dnl [for sdl_ttf support],
dnl [AS_HELP_STRING([--with-sdl_ttf],
dnl [Include sdl_ttf support])])
dnl Otherwise use 'enable':
PHP_ARG_ENABLE([sdl_ttf],
[whether to enable sdl_ttf support],
[AS_HELP_STRING([--enable-sdl_ttf],
[Enable sdl_ttf support])],
[no])
if test "$PHP_SDL_TTF" != "no"; then
dnl Write more examples of tests here...
dnl Remove this code block if the library does not support pkg-config.
dnl PKG_CHECK_MODULES([LIBFOO], [foo])
dnl PHP_EVAL_INCLINE($LIBFOO_CFLAGS)
dnl PHP_EVAL_LIBLINE($LIBFOO_LIBS, SDL_TTF_SHARED_LIBADD)
dnl If you need to check for a particular library version using PKG_CHECK_MODULES,
dnl you can use comparison operators. For example:
dnl PKG_CHECK_MODULES([LIBFOO], [foo >= 1.2.3])
dnl PKG_CHECK_MODULES([LIBFOO], [foo < 3.4])
dnl PKG_CHECK_MODULES([LIBFOO], [foo = 1.2.3])
dnl Remove this code block if the library supports pkg-config.
dnl --with-sdl_ttf -> check with-path
SEARCH_PATH="/usr/local /usr" # you might want to change this
SEARCH_FOR="/include/SDL2/SDL_ttf.h" # you most likely want to change this
if test -r $PHP_SDL_TTF/$SEARCH_FOR; then # path given as parameter
SDL_TTF_DIR=$PHP_SDL_TTF
else # search default path list
AC_MSG_CHECKING([for sdl_ttf files in default path])
for i in $SEARCH_PATH ; do

done
fi
if test -z "$SDL_TTF_DIR"; then

AC_MSG_ERROR([Please reinstall the sdl_ttf distribution])
fi
dnl Remove this code block if the library supports pkg-config.
dnl --with-sdl_ttf -> add include path
PHP_ADD_INCLUDE($SDL_TTF_DIR/include)
dnl Remove this code block if the library supports pkg-config.
dnl --with-sdl_ttf -> check for lib and symbol presence
LIBNAME=SDL2_ttf # you may want to change this
LIBSYMBOL=TTF_Init # you most likely want to change this
dnl If you need to check for a particular library function (e.g. a conditional
dnl or version-dependent feature) and you are using pkg-config:

dnl If you need to check for a particular library function (e.g. a conditional
dnl or version-dependent feature) and you are not using pkg-config:
