The split on a per-arch basis is required because bitbake cannot detect
that a generic package (architecture 'all') built by recipes running for
different architectures will produce the same results. The split also
per distro is for consistency reasons only.

.PHONY is not needed (and wasn't consistently used anyway). And that
missing && before the last export was apparently not critical as well.

This reduces the risk that a hard reset or power loss after the
regeneration leaves invalid key files behind, thus prevents that sshd
comes up again.

We do not yet have a good algorithm for automatically adding build
dependencies to the sdk beyond the basic set, let's allow users to
append what they need by appending SDK_PREINSTALL. Analogously to other
images, also allow to install self-built packages, consequently using
SDK_INSTALL.
Based on original patch by Le Jin.

Two issues:
1. I've tried the following:
. ./isar-init-build-env build
bitbake -c do_populate_sdk mc:qemuarm-buster:isar-image-base
When I look into tmp/deploy/images/qemuarm/sdk-debian-buster-armhf.tar.xz,
etc/apt/sources.list.d/isar-apt.list is not present. Am I missing anything?
2. The series still removes isar-apt description in p11.
With kind regards,
Baurzhan.

Was that with SDK_INCLUDE_ISAR_APT = "1"? It's opt-in now, see patch 9.

It's opt-in now, the common case for most users remains setting
SDK_INSTALL. We are only leaving the option to ship all the packages,
including all the useless ones, for special purposes.

Yes, I forgot to mention that, sorry for the confusion. The commands I used,
hopefully correct now:
. ./isar-init-build-env build
echo 'SDK_INCLUDE_ISAR_APT = "1"' >>conf/local.conf
echo 'ISAR_CROSS_COMPILE = "1"' >>conf/local.conf
time bitbake -c do_populate_sdk mc:qemuarm-buster:isar-image-base

sudo tar Jxf sdk-debian-buster-armhf.tar.xz
ls sdk-debian-buster-armhf/etc/apt/sources.list.d/isar-apt.list
ls: cannot access 'sdk-debian-buster-armhf/etc/apt/sources.list.d/isar-apt.list': No such file or directory

I'm referring to the following hunk:

-
-:~# dpkg -l | grep crossbuild-essential-armhf
-ii crossbuild-essential-armhf 12.3 all Informational list of cross-build-essential packages
-
- - Install needed prebuilt target packages.

This explains to the user how Debian multiarch works with option 2. This
example works inside or outside of the chroot. We should not be removing
documentation for a supported use case, thus NAK here.
3. In 08/16: Suggest "conpilation" -> "compilation".

OK, need to check again. Cannot explain yet why that should happen,
given the change in patch 9. Maybe I have a regression further down the

This hunk looks pointless to me. Why should the user try out all that
stuff? It's the duty of the SDK creator to do that upfront and ship a
properly working package.

Trying in the context of SDK -- that's a matter of taste, I like when some
background is presented rather than "do 1, 2, 3", sometimes without
understanding what I'm really doing. The hunk explains how Debian officially
handles cross-building with multiarch, so I'd be reluctant to remove that
completely. Maybe we could make it a separate section on Debian basics or
details how SDK option 2 is implemented.

I wanted to avoid scattering the issue over many mails -- but no problem, I can
do it.

I'm all for adding relevant information, but this one does not qualify.
Checking for the toolchain being install was always completely pointless
in the context of an SDK that always has this pre-installed according to
our recipes. And since isar-apt is now a special case and SDK_INSTALL
will ensure that all required packages are already installed, the second
hint is also irrelevant for normal users. It is only for the case of
SDK_INCLUDE_ISAR_APT = 1 *and* SDK_INSTALL *not* listing self-built
devel packages needed for building applications.
If you have other information that may help users with using the SDK in
chroot mode, feel free to add that on top.

Thanks, isar-apt.list is now available. However, when I enter the chroot, an
attempt to run arm-linux-gnueabihf-gcc results in:
-bash: arm-linux-gnueabihf-gcc: command not found

Yes, it might be confusing in the context of SDK. The section is meant as a
story and not a literal instruction. It tells the user that he can sudo apt-get
install crossbuild-essential-armhf libhello-dev:armhf and build his application
on the host with stock Debian, without any SDK. It describes the official
Debian build tooling and is certainly not limited to the chroot mode, while the
SDK is a convenience offer so that developers famliar with Yocto can start
right away before they learn Debian tools. Checking for the toolchain shows how
stuff works rather than verifying that the recipes have done their job.

Yes, so, it is a supported use case and must remain documented.

I don't have new material to add. The existing wording is good enough for me.
After the compiler is fixed, I'd be ready to apply the series while keeping the
discussed section till we have a suitable replacement.

Checking... Nope, works fine here:
- echo 'SDK_INCLUDE_ISAR_APT = "1"' >> conf/local.conf
- bitbake -c populate_sdk mc:qemuarm-buster:isar-image-base
- sudo tar xJf
/work/build/tmp/deploy/images/qemuarm/sdk-debian-buster-armhf.tar.xz

Please provide more details what you did.

This section is part of the SDK, not the user manual. So the context is
not as broad as you describe it here.

Then we need README generation - because all this only makes sense in
that non-default case. I don't see much value, though.

No, that section will not stay for the common case. I will add the
relevant parts in case SDK_INCLUDE_ISAR_APT = 1 and still drop the
irrelevant ones (toolchain check).

Thanks for the details! Turns out I made a mistake while applying the series.

As discussed offline, I'd like to have a consensus here. To summarize, your
point is that the description is not necessary if README.sdk is used as a
literal howto, and that the deeper message is only clear for expert users, who
know that anyway. Given these questions, I agree with the answers. My question
is a different one: Multiarch is Debian's unique feature for embedded
development, and we should be covering that somewhere in the docs. As a
solution, I'd like to enhance the existing docs instead of removing them. I've
checked the user manual, the topics are covered there. I've applied v4. As
agreed, the enhancements can still be implemented, I can provide them on top.
With kind regards,
Baurzhan.

When run inside the unpacked SDK, this script tunes interp and rpath
entry in relevant binaries so that the cross conpilation tool can be
called outside of the chroot, irrespective of the host distribution.
Then only "--sysroot /path/to/sdkroot" needs to be passed to the
compiler.
The script also supports restoring the original chroot-mode when invoked
with the --restore-chroot option.

-Building applications for targets in ISAR takes a lot of time as they are built under QEMU.
-SDK helps to develop applications for target platform in crossbuild environment.
+ISAR Target SDK
+===============
-SDK contains cross-toolchain for target architecture and a copy of isar-apt repo with
-locally prebuilt target debian packages.
+This SDK helps to develop applications for an ISAR target platform in a
+crossbuild environment. It contains a cross-toolchain and development packages
+corresponding to the original target.
- - First one have to mount the system directories for proper operation in chroot environement.
-Just call supplied with sdk tarball in udo rootfs as an argument to the script `mount_chroot.sh`:
+The SDK can be used in two ways, described in the following.
-$ sudo mount_chroot.sh <sdk_rootfs>
- - chroot to isar SDK rootfs:
+Option 1 (recommended): Use cross-compiler in host environment
+--------------------------------------------------------------
+
+After unpacking the SDK at the desired location, it has to be relocated once:
+
+$ <sdk_rootfs>/relocate-sdk.sh
+
+Now you can add <sdk_rootfs>/usr/bin to the local path or adjust your project
+to call the cross-compiler from the SDK.
+
+
+Option 2 (fallback): Build inside chroot
+----------------------------------------
+
+First you have to mount the system directories for proper operation into the
+chroot environment. Call the helper script supplied with SDK tarball:
+
+$ sudo <sdk_rootfs>/mount_chroot.sh <sdk_rootfs>
+
+Bind-mount the project into the rootfs:
+
+$ sudo mount -o bind /path/to/project <sdk_rootfs>/mnt
+
+If you have relocated the SDK previously for using option 1, you need to call
+this next:
+
+$ <sdk_rootfs>/relocate-sdk.sh --restore-chroot
+
+Then chroot into the SDK rootfs:
$ sudo chroot <sdk_rootfs>
- - Check that cross toolchains are installed
-
-:~# dpkg -l | grep crossbuild-essential-armhf
-ii crossbuild-essential-armhf 12.3 all Informational list of cross-build-essential packages
-
- - Install needed prebuilt target packages.
-

-:~# apt-get install libhello-dev:armhf
-

-
-:~# dpkg -L libhello-dev

Allow building and installing 32-bit packages an 64-bit architectures
that support this. Namely, these are amd64 and arm64 for us so far,
minus stretch-amd64 which lacks crossbuild-essential-i386 in that
version.
Control the target architecture of a package is added via the
PACKAGE_ARCH variable that defaults to DISTRO_ARCH. When set to
COMPAT_DISTRO_ARCH, the package is built for i386 on amd64 and armhf on
arm64.
If the build environment and the target image should contain the compat
arch is controlled via setting ISAR_ENABLE_COMPAT_ARCH to 1.

Looks like a clean implementation, thanks. Applied 12-15/16 to have this in

Furthermore, remove the reference to qemu because Isar also supports

+
+Some architectures, under Isar amd64 and arm64 so far, support running 32-bit
+legacy applications on 64-bit kernels. Debian supports this via the multiarch
+concept.
+
+Isar can build 32-bit packages as part of a 64-bit image build and also enable
+the image with the necessary packages. To activate the compat mode of a build,
+set `ISAR_ENABLE_COMPAT_ARCH = "1"` in `local.conf`. Packages that shall be
+built for the compat arch need to be tagged individually by setting
+`PACKAGE_ARCH = "${COMPAT_DISTRO_ARCH}"` in the package recipe. Non-tagged
+packages will continue to be built for the primary target architecture.

Strike this, nonsense. Got confused by the levels of chroots. New
version will follow that retries the key addition itself, inside the chroot.

We have a similar implementation which also kills the agent afterwards, will
post as well.
With kind regards,

We have recurring issues in CI with the gpg-agent not being ready when
trying to use apt-key:
gpg: can't connect to the agent: IPC connect call failed
Work around this by connecting upfront to the agent, retrying that in a
bounded loop.

This one seems to work fine.
Not sure if killing the agent is needed. In most cases, Isar runs in
more (VMs) or less (containers) isolated environments anyway. I case it
doesn't, wouldn't killing possibly affects what the user started before
running Isar?
