No matter what I put in PATH or other environment variables the make install
would not find the arm-linux executables even though I could access them 
while not in make. Examining the Makefile did not enlighten me as to why.
So todays HORRIBLE HACK was to save the original /bin and then cp everything in staging_dir/bin to /bin. Hey, I don't like it either but if I don't try odd things I don't get anywhere with this.

Now the make install in player runs almost to the end finally terminating with

g++ -o player server.o -Wl,--export-dynamic  -lm ../server/libplayerdrivers/.libs/libplayerdrivers.a ../libplayercore/.libs/libplayercore.a ../libplayercore/.libs/libplayererror.a ../libplayertcp/.libs/libplayertcp.a /home/john/player-2.0.4/libplayercore/.libs/libplayercore.a /home/john/player-2.0.4/libplayerxdr/.libs/libplayerxdr.a ../libplayerxdr/.libs/libplayerxdr.a /home/john/player-2.0.4/libplayercore/.libs/libplayererror.a ../replace/.libs/libreplace.a -lpthread -lnsl -lrt -lz

../server/libplayerdrivers/.libs/libplayerdrivers.a: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

Does any one recognise why ld doesn't like ELF?

Questions
1)why will make install not access the directorys that are in my PATH variable
when I execute make install?
2)is ld saying I compiled roomba_comms with the wrong options?

Any other Ideas, or even a nicer HORRIBLE HACK would be appreciated.
I will check out 2 this evening.
