All,
I am currently trying to use C6run to add DSP optimizations to an existing c++ library. What I need to do is allow a piece of c++ code to allocate a piece of memory and pass it to a c function that I have compiled with c6runlib-cc. I understand that all memory references passed to a function to run to the DSP must be allocated with C6RUN_MEM_malloc. I have taken the recommended route of adding the following code to my c++ files:
extern void *C6RUN_MEM_malloc(size_t size);
extern void *C6RUN_MEM_calloc(size_t nelem, size_t elsize);
extern void C6RUN_MEM_free(void* ptr);
#define malloc(sz) C6RUN_MEM_malloc(sz)
#define calloc(n,sz) C6RUN_MEM_calloc(n,sz)
#define free(ptr) C6RUN_MEM_free(ptr)
All of the source compiles without a problem, but the linking fails with:
omap/matcher.o: In function `Matcher::createSobelImages(short*, int const*, unsigned char*, unsigned char*)':
matcher.cpp:(.text+0x44): undefined reference to `C6RUN_MEM_malloc(unsigned int)'
matcher.cpp:(.text+0x50): undefined reference to `C6RUN_MEM_malloc(unsigned int)'
matcher.cpp:(.text+0xa50): undefined reference to `C6RUN_MEM_free(void*)'
matcher.cpp:(.text+0xa58): undefined reference to `C6RUN_MEM_free(void*)'
etc etc
Since I am not using c6run to compile the c++ file (I understand it can't handle c++...) I need to give the linker a library that provides the C6RUN_MEM functions. I have looked through the C6run directories and found a few libraries that looked promising, but nothing was able to satisfy the linker. Can anyone point me in the direction of the library I need to link against to give my c++ functions access to the C6RUN_MEM functions?
Thanks,
Justin
