CMakeLists.txt file for building the Einit program

The CMakeLists.txt file for building the Einit initializing program must contain the following commands:

Example of sending the VfsEntity program the "-f fstab" argument of the main() function and the environment variable ROOTFS set to ramdisk0,0 / ext2 0:

set_target_properties (${vfs_ENTITY} PROPERTIES

EXTRA_ARGS

" - \"-f\"

- \"fstab\""

EXTRA_ENV

" ROOTFS: ramdisk0,0 / ext2 0")

When building this solution, the description of the main() function argument and the environment variable value will be automatically added to the init.yaml file when processing macros of the init.yaml.in template.

Example CMakeLists.txt file for building the Einit program

CMakeLists.txt

project (einit)

# Connect the library containing solution image build scripts.

include (platform/image)

# Set compile flags.

project_header_default ("STANDARD_GNU_11:YES" "STRICT_WARNINGS:NO")

# Configure the VFS program.

# By default, the VFS program is not mapped to a program implementing a block device.

# If you need to use a block device, such as ata from the ata component,

# you must define this device in the variable ${blkdev_ENTITY}_REPLACEMENT

# For more information about exported variables and properties of the VFS program,

# see /opt/KasperskyOS-Community-Edition-<version>/sysroot-aarch64-kos/lib/cmake/vfs/vfs-config.cmake

# find_package(ata)

# set_target_properties (${vfs_ENTITY} PROPERTIES ${blkdev_ENTITY}_REPLACEMENT ${ata_ENTITY})

# In the simplest case, you do not need to interact with a drive.

# For this reason, we set the value of the ${blkdev_ENTITY}_REPLACEMENT variable equal to an empty string

set_target_properties (${vfs_ENTITY} PROPERTIES ${blkdev_ENTITY}_REPLACEMENT "")

# Define the ENTITIES variable with a list of executable files of programs.

# It is important to include all programs that are part of the project, except the Einit program.

# Please note that the name of the executable file of a program must

# match the name of the target indicated in add_executable() in the CMakeLists.txt file for building this program.
