How sources are organized
Type make help to see the make help recipe usage.
Includes the main flags, macro aliases, and dir variables.
debug mode: compile all packages and apps to be run on router ram (/tmp subdirs) with debug messages and temporary paths: used in addition with receive script.
to compile tools and apps locally on host PC machine generally for safer/quicker debug way: generally used in addition with DEBUG flag.
to distinguish between .ipk packages creation and simple install: generally it is already invoked by main Makefile when needed.
Includes patch applied before compiling.
Organized into subdirs.
Patch files must have .diff extension.
Files must be named:
projectname_fwversion_dirname-patchordernum(3dgt)-patchcontent(title).diff .
Each patch file is assumed to be applied from git root with -p0 option.
Patch dirs:
apps - Built-in apps modifications: it contains subdirs.
crosstools - Toolchain modifications adaptations fixes.
kernel - Kernel source additions & adaptations.
misc - Source makefiles & environmental vars adaptations & modifications.
uclibc - Uclibc libs fixes, tunings, adaptations.
work - Work-thirdparty dir fixes, tunings, ...: it contains subdirs.
The scripts used.
Each script has its own built documentation inside.
apply_patch.sh - Apply source code diff patches before compiling.
dl_sources.sh - Download & extract source codes.
founddiff.sh - Found code differences between firmware versions.
git_info.sh - For commit versioning & changelog usage.
hostprepare.sh - Apt download & install necessary packets.
pack_fw.sh - Prepare firmware .zip pack after compiling.
opkg-utils-x.x.x - Dir containing packet building scripts & tools.
receive - Prepare debug environment on running router.
leds.sh - Led board treatment script & guideline.
renamediff.sh - Rename diffs from old firmware version to new one.
startup.sh - Initialize router for package installations.
tchainprepare.sh - Toolchain crosstools extract & patch modifications.
The workjob dir contaning the apps.
Includes app vars information and apps subdirs var list: a sort of rudimental Config.in for make menuconfig .
Here apps can be included or excluded from compiling.
See the related document: include a new app to make work recipe for more informations.
Includes dirs used on package installation, arch-dependent flag used on preprocessing compiling and linking.
Dynamically created at runtime by makefile: don't edit directly.
