===== Overview =====

Some puttering around notes on Pulsar Linux.

Two things:

  * the active development branch for Pulsar Linux is ''pulsar-x''
  * current development emphasizes the container-related images (''cube-dom0'', ''cube-essential'', etc), not so much standard images like ''core-image-minimal''

===== Getting Pulsar Linux =====

First, to support my standard GitHub workflow, I like to clone GitHub projects with the remote name ''github'' as I like to reserve the remote name ''origin'' for my fork of the project, to which I will push subsequent commits:

<code>
$ git clone \
    -b pulsar-x \
    -o github \
    --recurse-submodules \
    https://github.com/WindRiver-OpenSourceLabs/wr-core
</code>

===== Configuration to deal with warnings/errors =====

When building ''iasl-native'' (as part of ''cube-essential''), GCC 8.1.1 generates warnings/errors, so you need to add to ''local.conf'':

<code>
CFLAGS_append = " -Wno-error=stringop-truncation"
CFLAGS_append = " -Wno-error=format-overflow"
</code>

or just use ''bitbake -k'', I guess.
===== RW notes, minimally unedited =====

==== Clone ====

<code>
$ git clone -b pulsar-x --recurse-submodules \
    https://github.com/WindRiver-OpenSourceLabs/wr-core
$ cd wr-core
</code>

==== Initialize in-tree build ====

Not sure if ''LANG'' setting is necessary:

<code>
$ . ./init-intel-x86-env
$ export LANG=en_US.UTF-8
</code>

==== Optional VLC-related stuff ====

Even without VLC, should some of that stuff be added to cube-desktop?

<code>
$ cd ../layers/
$ git clone git://lxgitserver/git/users/rwoolley/meta-vlc.git
$ cd $BUILDDIR
$ bitbake-layers add-layer ../layers/meta-vlc/
# Add the following to conf/local.conf
PACKAGECONFIG_append_pn-vlc = " sdl mad vpx vorbis ogg x264 libva"
PACKAGECONFIG_append_pn-ffmpeg2 = " libvorbis mp3lame theora vaapi vpx "
# For signage add:
LICENSE_FLAGS_WHITELIST="commercial"
CUBE_DESKTOP_EXTRA_INSTALL += " vlc ffmpeg2 git python3 python3-pip ristretto "
</code>

==== Machine ====

Might as well build for 64-bit:

<code>
MACHINE ?= "qemux86-64"
</code>

By default, won't it build for 32-bit?
==== Build ====

<code>
$ bitbake cube-desktop cube-dom0 cube-essential
</code>

==== Relevant generated artifacts ====

  * ''bzImage''
  * ''cube-builder-initramfs-intel-corei7-64.cpio.gz''
  * ''cube-desktop-intel-corei7-64.tar.bz2''
  * ''cube-dom0-intel-corei7-64.tar.bz2''
  * ''cube-essential-intel-corei7-64.tar.bz2''
