Zybo Z7_20 SDX 2017.4 moving functions to HW ERROR!

[Laumont]

Hi! I've been trying to execute a simple matrix multiplication (with large dimension) on SDx 2017.4 on a Zybo Z720 board. I used the reVISION repository on GITHUB  (https://github.com/Digilent/reVISION-Zybo-Z7-20 ) to create the platfom and to export it to my Windows Host. When debugging and releasing the app without any function into HW it works perfectly fine, no errors no warnings.

But I've tried to toggle the function that computes the matrix multiplication into  HW and the next error appears:

"C:/zybo_z7_20/export/zybo_z7_20/sw/sysroot/usr/include\malloc.h:38:14: error: declaration conflicts with target of using declaration already in scope.

extern void *malloc (size_t __size) throw () __attribute__ ((__malloc__)) ;

Can anybody help me understand? I don't know if its something related to the board or if I need to do something else before toggleling any function to HW.

I attach the sds.log that the error says to review.

Thanks in advance!!
