你的条件分支语句多于1，if与else配对出现了冲突，加上花括号就好了
if(count<=3) { // here
disp_count();
if(strcmp(password_text,password)==0)
printf("Access granted!\n");
else
printf("Access denied!\n");
gtk_entry_set_text(GTK_ENTRY(password_entry),""); } // here
else
printf("You try more than three times!\n");
gtk_main_quit();
if(strcmp(password_text,password)==0)
printf("Access granted!\n");
else
printf("Access denied!\n");
gtk_entry_set_text(GTK_ENTRY(password_entry),"");
if和else倒换一下.
strcmp好像只能比较字符串。如果密码含有数字就无法比较了。
