[RTnet-users] rtnet compiling Error

[★ 柳]

My system is:
 redhat 9.0
 linux-2.4.20 kernel with legacy-2.4.20.patch
 rtai-3.0r2

besides, the rtai installing is completed without any problem.

 

But there are problems in the rtnet installing. The version is rtnet-0.6.0. There is the same result with rtnet-0.6.1 as I did.

 

The rtnet's built directory is not same with its source directory.
The source directory is "/usr/src/rtnet/rtnet" and
the built directory is "/usr/src/rtnet/rtnet-obj".

 

I did it as the following:

# cd /usr/src/rtnet/rtnet-obj
# ../rtnet/configure --with-rtai=/usr/realtime --enable-allpci --enable-rtcap --enable-proxy
# make

the output is:

The file "simpleclient.c" includes the header file "rtnet.h". There is the definition of rt_socket,...in the file "rtnet.h". Why did the error happen?
How should I resolve the problem?

 

BTW: "rtai_lxrt" is installed normally.

 

Thanks in advance.
