Re: [Gumstix-users] Gumstix /w OE and Robostix - How do I get them to work?

[smerry <seb...@gm...>]

That worked! Thanks for the help, I now have the i2c-io.hex file on the
Robostix, and the red led is flashing.

I tried to put on one of the applications I made previously for my other
gumstix/robostix (which has build-root on it). It utilized the UARTS and ADC
on the robostix, and it worked great when I had my build-root version.
However now, when I try to run the app it complains that it cannot find my
file, simply called "main." I am not very skilled with Linux but I tried
changing the permissions on the file to 755, then I tried to run it by
typing "main", "./main", "source main", and I even moved it to my /usr/bin.
However every time it complained that it couldn't find "main."

"-sh: ./main: not found"

Does this have anything to do with the fact that I moved over to OE? Do I
need to rebuild my executable? If so how? I had all my files in the
/robostix/gumstix/<myDir> before, but now in OE that is all gone it seems.

This is the make file I had for my build-root version:

---------------------------------------------- END MAKEFILE


That make file would generate the executable, then I would send that over to
my gumstix and I could run it with "./main". What do I need to do to compile
my code now the the Common and Shared dirs have disappeared?

I tried to make my own bitbake .bb file however it complained about tons of
things being unreferenced so obviously it isn't finding the other files it
needs. All I did was set its DEPENDS variables to "robostix-module i2c"
