Spot 安装和使用

安装

./configure
make
make install

命令行执行时常见错误：

ltl2tgba: error while loading shared libraries: libspot.so.0: cannot open shared object file: No such file or directory

原因：
在程序加载期间找不到动态链接库libspot.so(libspot.so.0)

the_sam@sam-PC:/etc$ echo $LD_LIBRARY_PATH
:/home/the_sam/z3/build  

可见，LD_LIBRARY_PATH中确实没有libspot.so

解决：
添加libspot.so 的路径到LD_LIBRARY_PATH
libspot.so的路径可通过命令：whereis libspot.so得到

相关知识：
PATH是可执行文件路径
LIBRARY_PATH是程序编译期间查找动态链接库时指定除了系统默认路径之外的其他路径
LD_LIBRARY_PATH是程序加载运行期间查找动态链接库时指定除了系统默认路径之外的其他路径

ltl2ba

例子Ga：

buchi自动机

dot格式

the_sam@sam-PC:/etc$ ltl2tgba 'Ga' -d
digraph "Ga" {
  rankdir=LR
  label="
[Büchi]"
  labelloc="t"
  node [shape="circle"]
  I [label="", style=invis, width=0]
  I -> 0
  0 [label="0", peripheries=2]
  0 -> 0 [label="a"]
}
