How to bring absolute path of code replacement library to makefile generated during Software In Loop build?

I use a Code replacement library but in a directory outside the Simulink Project root folder. Hence, the path is metioned relatively. This creates a problem in build because, the INCLUDES_BUILDINFO contains now relative path.

simple question is: How to absolutize the relative path of code replacement library in makefile generated during Software In Loop build?

note: Code generation is successful, only Build fails.

Hi Noufal,

If you’re managing paths via Simulink Project, reference project variables in your include directories (e.g., Custom Code > Include directories) and let Simulink expand to absolute paths during build:

• Use $(PROJECT_ROOT) or a custom variable (e.g., $(CRL_DIR)) defined in Project Files > Settings > Project Paths/Variables.
• In model config: Include directories = $(CRL_DIR)/include

During code generation and build, Simulink replaces these tokens with absolute paths, which resolves the makefile issue.
