Question

我有一个非常简单的Z3程序示例如下：

    final Spinner spinnerLessonDuration = (Spinner) findViewById(R.id.spinnerLessonDuration);
    final ArrayAdapter<CharSequence> adapterLessonDuration = ArrayAdapter.createFromResource(this, R.array.lessonDuration, android.R.layout.simple_spinner_item);
    adapterLessonDuration.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    spinnerLessonDuration.setAdapter(
            new NothingSelectedSpinnerAdapter(
                    adapterLessonDuration,
                    R.layout.contact_spinner_row_nothing_selected_lesson_duration, this));

    spinnerLessonDuration.setOnItemSelectedListener(new setOnItemSelectedListener() {
           public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
               System.out.println("2 " + spinnerLessonDuration.getSelectedItem());
               if (spinnerLessonDuration.getSelectedItem() != null && "Other...".equals(spinnerLessonDuration.getSelectedItem().toString()))
               {
                           View view1 = (LayoutInflater.from(MainActivity.this)).inflate(R.layout.user_input, null);

                           AlertDialog.Builder alertBuilder = new AlertDialog.Builder(MainActivity.this);
                           alertBuilder.setView(view1);
                           final EditText userInput = (EditText) view1.findViewById(R.id.userinput);

                           alertBuilder.setCancelable(true)
                                   .setPositiveButton("Ok", new DialogInterface.OnClickListener() {

                                       @Override
                                       public void onClick(DialogInterface dialog, int which) {
                                           //EditText valueView = (EditText) view1.findViewById(R.id.license_value); //here
                                           if (userInput == null) Log.d("AA", "NULL");
                                           else {
                                               String value = userInput.getText().toString();
                                               Log.i(value, "1");


                                           }


                                       }
                                   });
                           Dialog dialog = alertBuilder.create();
                           dialog.show();

               }


           }

           }
     );

此示例程序可以在Z3在线编译器中执行，没有任何问题。但是，当我想使用命令行提示符执行相同的程序时，使用以下命令：

(declare-const a Int)
(declare-fun f (Int Bool) Int)
(assert (> a 10))
(assert (< (f a true) 100))
(check-sat)

我收到错误说：

Z3 <script path>

并且对程序中的每一行重复此错误。谁能帮我看看我做错了什么？

Answer 1

您正在使用SMT2格式。呼叫

z3 -smt2 <script path>

在命令行提示符中执行Z3脚本
