Compilation problems for a new board

[Maurizio Ferraris <ferring-at-inrete.it>]

Hi all,
I have two questions.

I have just installed the BDI, and I am trying to write the software 
interface for a different board. I have exchanged few mails with Ray, then 
following his suggestions, I decided to go public to the list.
As the first step of this process I tryed to compile without any changes in 
order to be sure to have a working source tree.
Since at the moment I am interested to the hardware interface, I decided to 
compile the emcmot directory only, changing to that directory ad issuing a 
make as in:
cd /usr/local/emc/src/emcmot
make PLAT=rtai

Now, I got few "No such file" for include files and I had to make some copy.
Particularly I copied (from where they were):
posemath.h into /usr/local/rcslib/rtai(include
emcpos.h into /usr/local/emc/plat/rtai/include
extintf.h into /usr/local/emc/plat/rtai/include
sim.h into /usr/local/emc/plat/rtai/include
parport.h into /usr/local/emc/plat/rtai/include
I don't know if all this is correct or if it was better to add more include 
paths to the compiler, but it worked. (Actually I didn't dare to change the 
Makefile and preferred to copy ...)

But when it went to link I got an error that 
/usr/local/emc/plat/rtai/lib/libpm.a was missing. The copy solution did not 
work because I don't have such a library in my whole hard disk. (I did a 
find / -name libpm.a)
What I am doing wrong? And this is the first question.

After this problem is fixed I will try to add a couple of files for my 
board (i.e. Ax4.c and Ax4.h) and I will have to add them to the makefile. I 
have a general understanding of how makefiles work and I am able to make 
small changes, but this particular makefile, have too many references and 
different cases and environment varibles set idontknowwhere ... that I find 
it difficult to follow. Can somebody give me some hint where to do the 
smallest changes in order to add a new board to the pack? And this is the 
second question.

Thank you very much for your help.
Mau.
