There are couple of questions about the building the can communications. I used the LTIBII method to build the helloworld, i tried doing the same thing for libsocketcan and canutils but i am missing the make file. in the ltib method, it says extract the source files to rpm/BUILD, the source files for the canutil and libsocketcan have .c and header files, do i move there all there? (the files that i got came from the /freescale/pkgs). and there is a line in there saying modify the code, which code are you refering to and what needs to be modified?
The only reason the example asks you to modify the code is that, later, when you run the different binaries on the target you can verify that all methods work.
For the projects you mention libsocketcan and canutils you can follow page 45 of the presentation to compile them.
