Unknown linux platform error

Question

I'm creating a DLL on a Red Hat flavor of linux.  However when i'm
running into the error "Unknown Linux platform" from
platdefines.h.  I don't know why its throwing this error or idea
of how to fix this problem.  If anyone could help it will be
greatly appriciated.

Hello Mess88,
I noticed in your first post you mentioned that you are trying to create a
DLL.  I would assume that you are actually trying to create .so file as
Linux is unable to handle DLLs.  I noticed that LabVIEW will still have a
default name of My DLL but it will actually be a .so file.
After looking through the platdefines.h file I was able
to determine the section that yields this error:
  #if defined(i386)
        #define ProcessorType   
kX86
        #define NI_BIG_ENDIAN   
    0
    #elif defined(__alpha)
        #define ProcessorType   
kDECAlpha
        #define NI_BIG_ENDIAN   
    0
    #elif defined(powerpc)
        #define ProcessorType   
kPPC
        #define NI_BIG_ENDIAN   
    1
    #elif defined(sparc)
        #define ProcessorType   
kSparc
        #define NI_BIG_ENDIAN   
    1
    #elif defined(mips)
        #define ProcessorType   
kMIPS
        #define NI_BIG_ENDIAN   
    1
    #elif defined(arm) || defined(__arm__)
        #define ProcessorType   
kARM
        #define NI_BIG_ENDIAN   
    0
    #elif defined(__x86_64__)
        #define ProcessorType   
kX64
        #define NI_BIG_ENDIAN   
    0
    #else
        #error "Unknown Linux platform"
    #endif
So it looks like it checks to see the type of processor that you have and if
it is not one of the types listed in the "if else" statements then it
will eventually get to the "Unknown Linux Platform" error.  Can
you verify what processor you are using?
Also, is this the first time that you have tried to implement a solution
like this before?  Did it ever work in the past or would you get this
error no matter what you tried to do.  Please just let me know if you have
any further questions!  I hope this helps!
Thanks!
