New KDS 3 problem - undefined reference to _sbrk

[davidsherman]

Yesterday things built after upgrading from KDS2 to KDS3, after fixing a couple problems.  Today I changed build configurations, built clean, and now I see this:

c:/freescale/kds_3.0.0/toolchain/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/lib/armv6-m\libg_s.a(lib_a-sbrkr.o): In function `_sbrk_r':

sbrkr.c:(.text._sbrk_r+0xc): undefined reference to `_sbrk'

What gives?  This built correctly under KDS2.  Interestingly, switching back to the other configuration seems to make it go away.

have you already added

--specs=nosys.specs

to the linker options?

Ah, I had missed that in the migration page write up.  I've bookmarked it.  Adding that to the linker options seems to have fixed that.  Thank you again, Erich!
