Ndless SDK 4.5 Compiling Error

(1/1)

Mumflr:
After finally getting the SDK to run and compile the "newlib" sample with no errors, I tried some of the other samples. When trying to compile the "colors" sample I get this error:


--- Code: ---mkdir -p .
nspire-ld colors.o -o ./colors.elf -Wl,--gc-sections

sbrkr.c:(.text._sbrk_r+0x18): undefined reference to `_sbrk'
collect2: error: ld returned 1 exit status
make: *** [colors.elf] Error 1
--- End code ---

when I try to compile my own simple HelloWorld program I also get an error saying, "sbrkr.c:(.text._sbrk_r+0x18): undefined reference to `_sbrk'"

I have looked at other people who have the same issue, but maybe because of other versions of Ndless, or different OS (by the way, I'm on mac), their advice doesn't seem to help.

Thank you for any assistance!
