Build Flags

Mat edited this page Oct 28, 2016 · 9 revisions

There are a couple of flags you can use to statically modify RIOT's behavior or to enable/disable certain features.

Usage Example:

QUIET=1 CFLAGS="-DSCHEDSTATISTICS -DDEVELHELP" make clean all

General

  • CFLAGS=-DSCHEDSTATISTICS - enable gathering and display of scheduler statistics
  • CFLAGS=-DDEVELHELP - enable certain code sections useful for development
  • CFLAGS=-DSCHED_TEST_STACK - enable (simple) testing for stack overflows
  • RIOT_VERSION=foo - build a tagged version of RIOT
  • RIOT_VERSION_OVERRIDE - override the version string - useful for comparing build sizes

Make Specific

  • QUIET=1 / QUIET=0 - enable/disable hiding of compiler invocations

Platform Specific

native

  • CFLAGS=-DNATIVE_AUTO_EXIT - terminate the native process after the last RIOT thread has exited.

Cortex-M based

  • TOOLCHAIN=gnu - build with GNU toolchain (GCC, binutils etc), this is the default
  • TOOLCHAIN=llvm - build with LLVM/Clang (some binutils tools are still required)

Module Specific

transceiver

  • CFLAGS=-DDBG_IGNORE - enable the transceivers ignore command (useful for debugging)
