Compiler settings via environment variables

bake has internal defaults for compiler settings (see e.g. “bake –toolchain-info GCC”). The commands and flags can be overwritten via environment variables.

Note that toolchain settings in Project.meta still have higher priority.

The supported environment variables are:

• BAKE_C_COMPILER

• BAKE_CPP_COMPILER

• BAKE_ASM_COMPILER

• BAKE_ARCHIVER

• BAKE_LINKER

• BAKE_C_FLAGS

• BAKE_CPP_FLAGS

• BAKE_ASM_FLAGS

• BAKE_ARCHIVER_FLAGS

• BAKE_LINKER_FLAGS

The internal defaults for flags are always empty. The internal defaults for commands differ depending on the toolchain. For GCC these are “gcc”, “g++” and “ar”.

Example:

export BAKE_CPP_COMPILER="gcc-9"
bake Debug
