hi,list
i download the
example(http://www.rts.uni-hannover.de/rtnet/lxr/source/addons/examples/raw-packets/
) to study and i add some code into it .
a few details about my hardware and software:
Linux Fedora Core 1 with 2.4.22 kernel
RTAI 3.0 r 4
RTnet 0.8
NIC compatible with RTL8139 chipset
but i don't understand the makefile.am of this example.my questions is
1)line 1,2 is for what?
2)in line 7,8, what is default (top_srcdir),(top_builddir)
3)because i use 2.4.x kernel not 2.6 ,whether the line 19,20,32 is
need?should i adapt sth?
4)line 36 is for what?
would someone kind to explain ,thank you for patience
Those examples are integrated in the build process of RTnet, therefore
they also come with makefile templates which are processed by autotools.
If you want your application to be build inside the RTnet tree, you
actually have to use those templates. This is not trivial, you will have
to changes several files: configure.ac, makefile.am in the directory
above your new directory and the makefile.am in the application
directory itself, which you should copy from an existing example. To
find out what has to be adapted, compare two examples and look in which
way the related makefiles differ.
The other, I would say preferred option: pick a makefile template from
the RTAI showroom (see www.rtai.org). For RTnet applications, it is
sufficient to add the include path of an RTnet installation directory to
the CFLAGS (e.g. "-I/usr/local/rtnet/include").
