stbenn opened a new issue, #16093: URL: https://github.com/apache/nuttx/issues/16093
### Description I am having issues with make recognizing file changes in my custom app. As a result, I need to `make clean` before every build which is not ideal. I believe the root cause is my app having `src` and `include` directories instead of being contained in one directory like the custom app example in the NuttX documentation. ## My Project Structure I made a sample git repo that demonstrates how I have the project set up (https://github.com/stbenn/NuttxCustomAppQuestion.git) to reference in addition to the following explanation. Directory structure: ``` ProjectDir/ nuttx/ apps/ external/ Make.defs Makefile custom_app/ (symlink) custom_app/ /include header_files.h /src custom_app.c other_sources.c KConfig Make.defs Makefile ``` Command used to link custom app directory: in `ProjectDir`, `ln -sr custom_app apps/external/custom_app` ### `apps/external/Makefile` ``` MENUDESC = "External Apps" include $(APPDIR)/Directory.mk ``` ### `apps/external/Make.defs` ``` include $(wildcard $(APPDIR)/external/*/Make.defs) ``` ### `custom_app/Make.defs` ``` ifneq ($(CONFIG_CUSTOM_APP),) CONFIGURED_APPS += $(APPDIR)/external/custom_app endif ``` ### `custom_app/Makefile` ``` include $(APPDIR)/Make.defs ifeq ($(CONFIG_CUSTOM_APP),y) PROGNAME = $(CONFIG_CUSTOM_APP_PROGNAME) PRIORITY = $(CONFIG_CUSTOM_APP_PRIORITY) STACKSIZE = $(CONFIG_CUSTOM_APP_STACKSIZE) MAINSRC = src/custom_app.c CSRCS = src/other_sources.c # This is how to add the include directory to the build system. # the path to the directory should match AFTER the symlink. So here it's apps/external/custom_app/include CFLAGS += ${shell $(INCDIR) "$(CC)" "$(APPDIR)$(DELIM)external$(DELIM)custom_app$(DELIM)include"} endif include $(APPDIR)/Application.mk .PHONY: clean clean:: rm -f src/*.su ``` Note: I have also experimented with using `CFLAGS += ${INCDIR_PREFIX}${APPDIR}/external/custom_app/include` in `custom_app/Make.defs` ## Desired Behavior The NuttX build system detects when changes are made to files in the subdirectories of `custom_app` without requiring a `make clean` before `make`. ### Verification - [x] I have verified before submitting the report. -- This is an automated message from the Apache Git Service.
