I have an STM32F072RB project using the toolchain ARM in C:\SysGCC\arm-eabi.
When I try to build my project and it includes an integer to string conversion using any function in the printf() family (sprintf(), vsnprintf(), etc.), I get the following linker error.
Severity Code Description Project File Line Suppression State
Error undefined reference to `_sbrk’ MyProject q:\gnu\newlib-nano\newlib-nano-2016q3\newlib\libc\reent\sbrkr.c 58
Error ld returned 1 exit status MyProject C:\[path to MyProject]\collect2.exe 1
Why is this happening, and how can I fix it?
I have the latest VisualGDB packages, as shown below.
