CUDD 执行中的分段错误

Question

我使用的编译：

   1)  ./configure --enable-dddmp --enable-obj --enable-shared --enable-static; make
   2)  gcc test.c -o testprogram -I /path/to/cudd-3.0.0/cudd -I /path/to/cudd-3.0.0/util -I /path/to/cudd-3.0.0/ -static -L /path/to/cudd-3.0.0/cudd/.libs/ -lcudd -lm

程序编译成功。我正在使用 cudd3.0.0 包。之后我在执行中遇到了这个分段错误：

请建议执行此操作的正确方法以及为什么会出现此错误？

我正在添加主函数：

int main (int argc, char *argv[])
{
    char filename[30];
    DdManager *gbm; /* Global BDD manager. */
    gbm = Cudd_Init(0,0,CUDD_UNIQUE_SLOTS,CUDD_CACHE_SLOTS,0); /* Initialize a new BDD manager. */
    DdNode *bdd, *var, *tmp_neg, *tmp;
    int i;
    bdd = Cudd_ReadOne(gbm); /*Returns the logic one constant of the manager*/
    Cudd_Ref(bdd); /*Increases the reference count of a node*/

    for (i = 3; i >= 0; i--) {
        var = Cudd_bddIthVar(gbm,i); /*Create a new BDD variable*/
        tmp_neg = Cudd_Not(var); /*Perform NOT boolean operation*/
        tmp = Cudd_bddAnd(gbm, tmp_neg, bdd); /*Perform AND boolean operation*/
        Cudd_Ref(tmp);
        Cudd_RecursiveDeref(gbm,bdd);
        bdd = tmp;
    }

    bdd = Cudd_BddToAdd(gbm, bdd); /*Convert BDD to ADD for display purpose*/
    print_dd (gbm, bdd, 2,4);   /*Print the dd to standard output*/
    sprintf(filename, "./bdd/graph.dot"); /*Write .dot filename to a string*/
    write_dd(gbm, bdd, filename);  /*Write the resulting cascade dd to a file*/
    Cudd_Quit(gbm);
    return 0;
}

是的，已解决。我没有在代码行的正确位置创建名为“bdd”的文件夹：

sprintf(filename, "./bdd/graph.dot");

现在，它正在执行。抱歉，我认为这是一些概念错误。
