ITA - ArchLinux vs Yocto : Day 2

November 2020 (1031 Words, 6 Minutes)

linux archlinux yocto

Ciao a tutti in questo post affronto la build di yocto su archlinux ma approcciandomi diversamente, su questa sezione la documentazione non include esplicitamente arch tra le distro supportate.

Quindi quello che andrò a fare e usare una delle distro supportate su docker e procederò a buildare al suo interno mantenendo la workdir su una cartella condivisa con l’host.

La distro che sceglo è Debian, per riprodurre l’esecuzione avvenuta con successo è necessario eseguire la segquenza di comandi necessari:

$ mkdir build_yocto
$ docker run -ti -v $(pwd)/build_yocto:/build_yocto --rm --name build_yocto debian # from now you are in container
$ apt update
$ apt install gawk wget git-core diffstat unzip texinfo gcc-multilib \
 build-essential chrpath socat cpio python python3 python3-pip python3 \ 
 pexpect xz-utils debianutils iputils-ping libsdl1.2-dev xterm \
 vim locales
$ vim /etct/locale.gen # enable a locale
$ locale-gen
$ useradd -m -s /bin/bash poky 
$ su - poky
$ cd /build_yocto/
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git fetch --tags
$ git checkout tags/yocto-3.1.3 -b my-yocto-3.1.3
$ source oe-init-build-env
$ bitbake core-image-minimal

Ora provo a riprodurre il primo tentativo fallito:

$ pwd # mi assicuro di essere nalla cartella giusta
.../build_yocto/poky 
$ git checkout morty
Branch 'morty' impostato per tracciare il branch remoto 'morty' da 'origin'.
Si è passati a un nuovo branch 'morty'
$ git log --name-status HEAD^..HEAD # con qusto comando vediamo l'ultimo commit
commit e56be3cee517c5262486136dbd6d649b68c3a8b7 (HEAD -> morty, origin/morty)

Da quello che possiamo vedere l’ulitma modifica su questo branch è stata apportata a Dicembre 2018, quindi usando la versione di debian disponibile in quel periodo dovrebbe funzionare.

Su Wikipedia a questa pagina sono riportati in ordine cronologico i rilasci di Debian, e quella che ci interessa è Debian Stretch

$ cd ../.. # Ci portiamo nella cartella che contiene build_yocto
$ ls
build_yocto
$ docker run -ti -v $(pwd)/build_yocto:/build_yocto --rm --name build_yocto debian:stretch # da adesso sarete loggati nel container
$ apt update
$ apt install gawk wget git-core diffstat unzip texinfo gcc-multilib \
 build-essential chrpath socat cpio python python-pip \
 xz-utils debianutils iputils-ping libsdl1.2-dev xterm \
 vim locales
$ vim /etct/locale.gen # enable a locale
$ locale-gen
$ useradd -m -s /bin/bash poky 
$ su - poky
$ export LC_ALL=en_US.UTF-8
$ export LANG=en_US.UTF-8
$ export LANGUAGE=en_US.UTF-8
$ cd /build_yocto/poky
$ source oe-init-build-env
$ bitbake core-image-minimal

Abbiamo 2 errori :

Per capire quali sono le distro supportate ho cercato la definizione della varibile SANITY_TESTED_DISTROS:

$ grep "SANITY_TESTED_DISTROS" -A 20 meta-poky/conf/distro/poky.conf

# OELAYOUT_ABI allows us to notify users when the format of TMPDIR changes in 
# an incompatible way. Such changes should usually be detailed in the commit

quindi ci serve Debian 8!!

Per la puliza, ci limiteremo a eliminare o a rinominare la cartella build, a seconda dello spazio disponibile.

Quindi riproviamo:

$ cd ../.. # Ci portiamo nella cartella che contiene build_yocto
$ ls
build_yocto
$ docker run -ti -v $(pwd)/build_yocto:/build_yocto --rm --name build_yocto debian:jessie # da adesso sarete loggati nel container
$ apt update
$ apt install -y gawk wget git-core diffstat unzip texinfo gcc-multilib \
     build-essential chrpath socat libsdl1.2-dev xterm python3 \
     python3-pip python cpio vim locales
$ vim /etc/locale.gen # enable a locale
$ locale-gen
$ useradd -m -s /bin/bash poky 
$ su - poky
$ export LC_ALL=en_US.UTF-8
$ export LANG=en_US.UTF-8
$ export LANGUAGE=en_US.UTF-8
$ cd /build_yocto/poky
$ source oe-init-build-env   

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
    core-image-sato
    meta-toolchain
    meta-ide-support

You can also run generated qemu images with a command like 'runqemu qemux86'

$ bitbake core-image-minimal

Ed ecco come ho risolto il problema di compilare vecchie versioni di yocto su sistemi non ufficialmente supportati o troppo aggiornati.
