Error when compiling application for ethernet

[Altera_Forum]

Hi All, 

  I am trying to develop an application for ethernet device. I am using open core device driver which comes with uCLinux.     To open an ethernet device i need to get a structure named net_device which is defined into netdevice.h. After including file netdevice.h and compiling application there are following errors displayed.    In file included from  D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/netdevice.h:28,  from test.c:3: D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/if.h:136: error: field `ifru_addr&#39; has incomplete type D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/if.h:137: error: field `ifru_dstaddr&#39; has incomplete type D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/if.h:138: error: field `ifru_broadaddr&#39; has incomplete type D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/if.h:139: error: field `ifru_netmask&#39; has incomplete type D:/TOOLS/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.uClibc_0.1.0/include/linux/if.h:140: error: field `ifru_hwaddr&#39; has incomplete type test.c:6: warning: return type defaults to `int&#39; test.c: In function `main&#39;: test.c:9: error: storage size of `dev&#39; isn&#39;t known test.c:14: warning: implicit declaration of function `write&#39; test.c:9: warning: unused variable `dev&#39; test.c:16:2: warning: no newline at end of file make: *** [test.o] Error 1 make: Target `all&#39; not remade because of errors.  Here is the part of my application code.. # include<stdio.h># include<fcntl.h># include<linux/netdevice.h>  main() {  int i,j=0;  const char* buf="hello";  struct net_device dev; }  Can anybody suggest anything for this? Thanks in advance.
