Passing pointers to functions in static libraries

Nino Paldan
Prodigy 20 points


Hello all,

We are in the middle of modularization of our code base. We are currently moving code into static libraries and have encountered some issues calling functions when passing pointers to them. We are using Code Composer v4/C2000 with  TMS320F28x DSP family. Below are some examples with the errors generated by Code Composer. It seems like it should be a simple matter but we are stuck and was hoping someone could shed some light on this. Is this a compiler or IDE issue?  Is it memory related? Or are we doing the calls wrong that the compiler (C2000) does not like? As always, it's an urgent issue :) Any help on this would be greatly appreciated.

Thanks in advance.


Case 1:

.c file

Uint16 *spiParams[2];

spiParams[0] = (Uint16 *) LO_SPEED_CLOCK;

spiParams[1] = (Uint16 *) EXTERNAL_AD_SPI_BAUD_RATE;

spi_init((Uint16 *) &spiParams); << call fails

 

Case 2:

.h file

typedef struct _HVFE_SEMAPHORE {

       HVFE_SEMAPHORE_OP    eSemOp;

       Uint16               uSemCount;

} HVFE_SEMAPHORE;

extern HVFE_SEMAPHORE g_spiSemaphore;

 

.c file

HVFE_SEMAPHORE g_spiSemaphore;

semaphore_ioctl((Uint16 *) &g_spiSemaphore); << call fails

    I'll examine one related set of error messages.  It appears that same error is repeated with several other symbols.

    This means that __ftable (written "_ftable" in C) is defined in 4 files: hvfeExternalAD.obj, Adc_Init.obj, Adc.obj and GenericFunctions.obj.  I presume these definitions occur in C source files of the same base name as the object files.  You can only have one definition of any global variable or function.  Please see http://c-faq.com/decl/decldef.html for a full discussion.

    You say you are trying to create libraries.  Perhaps you aren't creating the libraries correctly.  Creating a library requires use of the archiver, but not the linker.  How are you creating these libraries?

    Thanks and regards,

    Hello George,

    Thanks for your reply. To clarify about the setup, we have a Master project that we have taken bits out of and made into libraries. We do use the archiver to make the libraries and we have no issues there as far as we can tell. The problem arises when we include the library into the Master project and call functions in them. However this seems to only happen when we pass pointers(beginning to think that this is not the problem). We did take a look into the definitions and found some duplicates (fixed those), but some that the errors complain about don't even exist in said files. Symbols that has double underscores like so __ftable seems to not exist but the ones that has a single underscore do if we search for them without the underscore(does this make sense?). By the way, ftable does not exist with either double/single or without underscore in the project (not sure what ftable is to be honest, anyone?). We are going through all the definitions in the project and hopefully we'll get it resolved, if nothing else the code will get cleaner :)

    If you or anyone else roaming these forums have any other thoughts on this it would be greatly appreciated.

    Regards,

    -Nino

    It's probably the global FILE array in the compiler's run-time support library.  You'll get a reference to _ftable if you use the stdout, stdin, or stderr macros.
