   I have moved all the files in transarc into my
local computer. And just load arla into the kernel.
It works. Now I want to get some debug info
and reedited the file in /xfs/bsd/xfs_deb.c. And
then typed "make" but I got the following error:

% make
for i in include lib util ydr lwp rx rxdef lib/ko  rxkad xfs arlad conf
appl;  do (cd $i; make   all); done
for i in roken sl editline;  do (cd $i; make   all); done
SUBDIRS='bsd';  for i in $SUBDIRS;  do (cd $i && make   all); done

*** Error code 1

Stop.

Stop.

   I tried to do it for several times but I always got
this message. So could you tell me how I can fix this
problem? Thanks a lot.
best,
