运行fastdfs_client_php_v1.6.tar.gz中的fdfs_test.php时遇到问题，请教版主

happy_fish100

用gdb看一下。
gdb  fdfs_storaged   <corefile>

例如：
gdb  fdfs_storaged   core.1234

进去后可以看到调用堆栈。把函数堆栈贴一下吧，谢谢！

看来是storage_sync_delete_file ()和storage_sync_thread_entrance ()这里出了问题

非常感谢！你安装的版本是V1.22吧？

修改Makefile，编译时带上-g参数，然后重新编译fdfs_storaged。
make clean; make

这样用gdb就可以定位到代码行了，谢谢！

是的 我安装的是1.22版本

我按照版主你在6楼说的方法进行了操作，修改Makefile然后重新编译，得到了core dump文件

happy_fish100

如果编译时带上了 -g参数，gdb中可以看到源码文件名和代码所在行数的。
你确认运行的fdfs_storaged是重新编译后的吧？

只要gdb把出错时的代码行数打印出来，就可以直接定位到问题所在。

谢谢版主，我按照你6楼说的方法重新编译了fdfs_storaged，然后将其拷到/usr/local/bin下面，最后执行fdfs_storaged。

然后我通过浏览器再次执行了fdfs_test.php文件，这下没有出现文件被删除的机器上的进程退出的问题了，而且文件删除以后，同组的其他机器也及时同步了。

非常感谢版主不厌其烦的解答，以后研究FastFDS过程中遇到问题再来向版主请教！
