ax_restore_flags_with_prefix ¶

Synopsis ¶

AX_RESTORE_FLAGS_WITH_PREFIX(PREFIX, LIST-OF-FLAGS)

Description ¶

Restore the flags saved by AX_SAVE_FLAGS_WITH_PREFIX.

Expansion example: AX_RESTORE_FLAGS_WITH_PREFIX([GL], [[CFLAGS],[LIBS]]) expands to

  CFLAGS="$gl_saved_flag_cflags"
  LIBS="$gl_saved_flag_libs"

One common use case is to define a package specific wrapper macro around this one, and also restore other variables if needed. For example:

  AC_DEFUN([_AX_CHECK_GL_RESTORE_FLAGS], [
    AX_RESTORE_FLAGS_WITH_PREFIX([GL],[$1])
    AC_LANG_POP([C])
  ])

  # Restores CFLAGS, LIBS and language state
  _AX_CHECK_GL_RESTORE_FLAGS([[CFLAGS],[LIBS]])
