    Hi Gustavo

    
    I tried your suggestions.

    
    The first line didn't work because I seem to not have a build
    directory there.

    And the second one did exactly the same as mine did.

            you should replace the KERNEL_DIR
            definition in MAKEFILE. My suggestions:
        
          
          KERNEL_DIR:=/usr/src/linux-headers-$(shell
          uname -r)/build

        
        or
        KERNEL_DIR:=/lib/modules/$(shell
            uname -r)/build

             Hey Guys

              
              All im trying to do here is learn about make files and how
              to link linux header files stored in /usr/src/linux-headers-3.13.0-35-generic
              to my program that im writing.

              So far ive been getting the simplest of Kernel Modules to
              compile and load in Linux but nothing useful . The moment
              I delve deeper I seem to get missing header file errors
              when using "make".

              All I want to do is write from Kernel space into user
              space and visa verse. I will be dumping allocated PCI
              memory blocks into files.

              I will also have to edit registers of the PCI to be able
              to make triggers go off by setting bits high etc.

              But this is just an introduction to it all and im already
              having trouble compiling.

              
              Now im not 100% sure if its missing header files but the
              errors is quite large.

              
               This is my Pastebin of the C MODULE Code :

              
               pastebin.com/lWPBR8DJ 
              

               And here it the PASTEBIN of my MAKEFILE and its errors:

              
               pastebin.com/ffT1F26N

              
              ALSO...Does anybody know of a good tutorial on how to
              write a PCI driver in Kernel space using kernel
              modules...also how to send data from and to the module
              from UserSpace?
