我的程序怎么进不了main函数?
不知咋回事,我写的这个程序启动不了,进不了main函数,调试输出如下。

我写的另外一个程序能够正常运行,不知为什么这个却不行了。
以前多在windows下开发,linux开发没什么经验,还望大家多多指教!
------解决方案--------------------什么地方阻塞了,贴代码看看。
------解决方案--------------------进入main函数了。如果ld-linux.so.2加载进程映像有错误,gdb也可以调试进入main之前的代码。
进入main之前都是ld-linux.so.2和libc的工作,这个没必要调试。
lz另外一个程序的运行结果是什么样的?
------解决方案--------------------用strace命令跟踪..如果不熟悉该命令去网上查查strace资料,该工具也很使用
