Most commonly operations performed in Yocto - part 3

-
1.Generate dependency tree information in the dot syntax
bitbake -g core-image-minimal

The above command generates a dependency graph. Bitbake creates pn-buildlist, recipe-depends.dot and task-depends.dot files

pn-buildlist: Simple list of packages which are going to be build
recipe-depends.dot: Show dependencies between recipes
task-depends.dot: Shows dependencies between tasks.

 2. Displays environmental variables

bitbake -e <recipe/target name>

E.g: bitbake -e core-image-minimal | grep ^SDKMACHINE

 3. Enable verbose output of shell tasks

bitbake -v <recipe/target name>

E.g. bitbake -v core-image-minimal

 4.Continue bitbake even after error. This will be useful when you started a build and went for lunch and don't want the bitbake to stop if it is unable to fetch a file over Internet

bitbake -k <target>

E.g. bitbake -k core-image-minimal

 5. Force the target to run even if there is sstate-cache available for it

bitbake -f <target/recipe name>

E.g. bitbake -f busybox

bb.utils.contains yocto

bb.utils.contains  is most commonly used function in Yocto. grep in poky directory returned with 696 count. $ grep -nr 'bb.utils.contains' poky/ | wc -l 696 It's definition is present in 'poky/bitbake/lib/bb/utils.py' file This function returns third argument if the second argument is subset of the first argument else returns fourth argument Let's take an example to understand this. You can see from the above screenshot, when the second argument is a subset of first argument, "present" was returned, else "notpresent" was returned We can also use bb.utils.contains inside if loop. This we can use inside a recipe. if ${@bb.utils.contains('SOMEFLAG','NEWVALUE3','true','false',d)}; then     FOO = 'HELLO' fi

Difference between RDEPENDS and DEPENDS in Yocto

-
We normally observe these two (RDEPENDS and DEPENDS) whenever we open any recipe. What should we choose when we write our own recipe. DEPENDS -> Build Time Dependency RDEPENDS -> Run Time Dependency DEPENDS: When a recipe 'A' is DEPENDS on recipe 'B'. In this case, Bitbake first builds recipe 'B' and then recipe 'A' E.g. You need 'dbus' to be built before 'wpa_supplicant'. RDEPENDS: When a recipe 'A' is RDEPENDS on recipe 'B'. In this case, Bitbake deploys 'B' on the target system when it deploys 'A'.  E.g. 'perf' RDEPENDS on 'bash' In other words, DEPENDS are those set of packages that should be available while building package, whereas RDEPENDS are set of packages that should be available during execution of the program.

make config vs oldconfig vs defconfig vs menuconfig vs savedefconfig

Building the Linux Kernel is a two-step process: Configuring the Kernel options Building the Kernel with those options. There are many methods available for configuring the kernel. make config: Text-based Configuration.  Options are prompted one after another. All options need to be answered Access to former options is not possible make menuconfig: Menu-driven user interface Allows to navigate forwards and backward directly between features Allows to load and save files with filenames different from ".config" Provides search feature It uses ncurses library for GUI. If the ncurses library is not installed, make menuconfig option fails. To install ncurses library on Ubuntu: sudo apt-get install libncurses5-dev make defconfig: Creates a ".config" file with default options from the ARCH supplied defconfig Configurations are generally stored in the directory: arch/$(ARCH)/configs $ ls arch/x86/configs/ i386_defconfi
