我正在使用 Windows 操作系统并在 Cygwin 中输入：wish -f ispin.tcl打开 ispin 界面。我打开一个文件test.pml，其中包含：

byte state = 2;

proctype A()
{   (state == 1) -> state = 3
}

proctype B()
{   state = state - 1
}

init
{   run A(); run B()
}

之后，我使用种子 = 123 的随机方式运行它。结果打印在输出中没有问题：

  0:    proc  - (:root:) creates proc  0 (:init:)
Starting A with pid 1
  1:    proc  0 (:init::1) creates proc  1 (A)
  1:    proc  0 (:init::1) test.pml:12 (state 1)    [(run A())]
Starting B with pid 2
  2:    proc  0 (:init::1) creates proc  2 (B)
  2:    proc  0 (:init::1) test.pml:12 (state 2)    [(run B())]
  3:    proc  2 (B:1) test.pml:8 (state 1)  [state = (state-1)]
  4:    proc  1 (A:1) test.pml:4 (state 1)  [((state==1))]
  4:    proc  2 (B:1) terminates
  5:    proc  1 (A:1) test.pml:4 (state 2)  [state = 3]
  5:    proc  1 (A:1) terminates
  5:    proc  0 (:init::1) terminates
3 processes created

当我尝试验证此模型时出现问题。验证结果为：

verification result:
spin -a  test.pml
gcc -DMEMLIM=1024 -O2 -DXUSAFE -DSAFETY -DNOCLAIM -w -o pan pan.c
./pan -m10000 
Pid: 3952
spin: error, the version of spin that generated this pan.c assumed a different wordsize (4 iso 8)

我该如何解决这个问题？我在互联网上搜索，但找不到可以帮助我的东西。

注意：我没有更改任何验证属性： ispin_interface_verification_properties

上述错误的解决方案是为 32 位版本的 Windows 安装 Cygwin，即使我的笔记本电脑是 64 位的。这是因为spin 的可执行文件仅适用于 Windows 32 位，因此它们必须按照我的理解匹配。

安装完 Cygwin ( gcc, cpp, make) 后，我们将spin,ispin和test文件移动到新的 Cygwin 文件夹 ( C:\cygwin\)。

当我们尝试再次运行并验证模型时，不需要任何其他修改，我们可以看到正确的输出，没有错误：

verification result:
spin -a  test.promela
gcc -DMEMLIM=1024 -O2 -DXUSAFE -DSAFETY -DNOCLAIM -w -o pan pan.c
./pan -m10000
