Had this same issue. I fixed it by deleting newlib/_sbrk.c.
from cubemximporter.
I have checked on the Internet and find out this blog works fine with my issue:
https://mcuoneclipse.com/2014/03/16/freertos-malloc-and-sp-check-with-gnu-tools/
However, I don't understand why this function "_sbrk" has been declared multiple times? Thanks.

I've been having the same issue. For a temporary fix, on the src/syscalls.c
file, comment out the _sbrk()
function. So from line 117 to 138, comment it out. This should compile the program without any error.
Would love to know if there are any permanent fix for this though.
Lines in question:
caddr_t _sbrk(int incr)
{
extern char end asm("end");
static char *heap_end;
char *prev_heap_end;
if (heap_end == 0)
heap_end = &end;
prev_heap_end = heap_end;
if (heap_end + incr > stack_ptr)
{
// write(1, "Heap and stack collision\n", 25);
// abort();
errno = ENOMEM;
return (caddr_t) -1;
}
heap_end += incr;
return (caddr_t) prev_heap_end;
}

Have the same issue. Compiled successfully after omitting system/src/newlib/_sbrk.c
from build.
The newlib
implementation is different than the one in src/syscalls.c
:
_sbrk(int incr)
{
extern char _Heap_Begin; // Defined by the linker.
extern char _Heap_Limit; // Defined by the linker.
static char* current_heap_end;
char* current_block_address;
if (current_heap_end == 0)
{
current_heap_end = &_Heap_Begin;
}
current_block_address = current_heap_end;
// Need to align heap to word boundary, else will get
// hard faults on Cortex-M0. So we assume that heap starts on
// word boundary, hence make sure we always add a multiple of
// 4 to it.
incr = (incr + 3) & (~3); // align value to 4
if (current_heap_end + incr > &_Heap_Limit)
{
// Some of the libstdc++-v3 tests rely upon detecting
// out of memory errors, so do not abort here.
#if 0
extern void abort (void);
_write (1, "_sbrk: Heap and stack collision\n", 32);
abort ();
#else
// Heap has overflowed
errno = ENOMEM;
return (caddr_t) - 1;
#endif
}
current_heap_end += incr;
return (caddr_t) current_block_address;
}
I don't have enough C/Arm knowledge. Which one is outdated?
