This commit is useful if there is a need to generate a file
that can be included into the application at build time.
The file can also be compressed automatically when embedding it.
Files to be generated are listed in
generate_inc_file
generate_inc_gz_file
variables.
How to use this commit in your application:
1. Add this to your application Makefile
SRC = $(ZEPHYR_BASE)/<your-app-dir>/src
include $(ZEPHYR_BASE)/scripts/Makefile.gen
2. Add needed binary/other embedded files into src/Makefile
to "generate_inc_file" or "generate_inc_gz_file" variables:
# List of files that are used to generate a file that can be
# included into .c file.
generate_inc_file += \
echo-apps-cert.der \
echo-apps-key.der \
file.bin
generate_inc_gz_file += \
index.html
include $(ZEPHYR_BASE)/scripts/Makefile.gen
3. In the application, do something with the embedded file
static const unsigned char inc_file[] = {
#include "file.bin.inc"
};
static const unsigned char gz_inc_file[] = {
#include "index.html.gz.inc"
};
The generated files in ${SRC}/*.inc are automatically removed
when you do "make pristine"
