[dpdk-dev] [PATCH 01/10] examples/fips_validation: fix build with pkg-config

[David Marchand]

When this example started using rte_cryptodev_sym_session_pool_create,
the part for pkg-config builds was not updated.

Fixes: 261bbff75e34 ("examples: use separate crypto session mempools")

Compiling examples out of meson must be tested so that those examples

This is based on Bruce patch [1], waiting for it (or an equivalent) to be

I was initially confused by this, because they build fine for me. However,
I realised I was running the build from within the examples source folder,
rather than as installed in the install folder. The examples directory
seems more flattened there, which is the cause of the problems. I will
investigate.

Thanks for the work David, this is great. I'll see about doing more cleanup
on the skipped list, particularly how we install the examples in the
"share" folder, but until then this is great progress.

[dpdk-dev] [PATCH v2 11/11] devtools: compile all buildable examples with pkg-config

[David Marchand]

Rather than just installing all examples, we can use the build checks to
filter out any examples that are missing dependencies or are otherwise
unbuildable on the current system.
Introduce a new "buildable" special value for the -Dexamples= meson
option, this way existing behavior on installing all examples is
preserved.

Select only buildable examples and test their compilation for the
x86-default target.

Note for maintainers/users of the script: for existing environments,
the x86-default target might get broken by this patch since the script
now tries to build all "installed" examples and dependencies for some
might be unfulfilled.
To fix this temporary situation, you can either delete the whole
directory or reconfigure it:
$ meson configure $DPDK_BUILD_TEST_DIR/build-x86-default \
  -Dexamples=buildable

Changelog since v1:
- rebased on main,
- introduced a new "buildable" special value for the -Dexamples option,
- installation of the "multi-level" examples has been fixed, so
  corresponding exceptions have been removed,
- a fix for the vhost is waiting in next-virtio, I assume it will get
  pulled before this series,
- the only remaining exception is for vm_power_manager which is broken,

If next-virtio is not pulled yet, we can add a temp:

Sorry for the last-minute comment, but I wonder for this check if we can do
better by adding into each makefile something like:

CONFIG_DEFINES=$(shell $(CC) $(CFLAGS) -dM -E - < /dev/null)

Then we can easily do multiple checks for vars as needed using findstring,
e.g.

ifeq ($(findstring RTE_CRYPTO_SCHEDULER,$(CONFIG_DEFINES),)
$(info No crypto scheduler found)
else
...
endif

Whatever approach we use here, I'd like applicable across all makefiles for
consistency, and shelling out per-value seems wasteful. Pulling all macro
values also allows checks for architecture and instruction set levels too,
if so desired.

I'm not sure my "suggested-by" should be on this, since the idea of adding
an extra buildable option is not mine here. I actually think I prefer the
previous approach based on your original suggestion of always skipping
unbuildable examples. Two reasons for that:
* I'm not fully sure of the value of installing examples that can't be
  built, which was the original issue you raised.
* I don't like mixing together two separate things - examples to build, and
  examples to install in a single option.

Therefore, I think we should choose one of two less confusing paths -
either lets just always install all applications, or let's always install
only those apps which can be built. I'm not massively concerned either way
which is chosen, but I don't think we should try and support both and
overload options to do so.

I was not sure how to credit my copying of the meson bits :-).

Thomas objected that all examples have always been provided regardless
of the configuration.
The examples serve as documentation and the API/guides documentations
are all compiled anyway.

Yes, I am not entirely happy either.
Time is ticking, I'll just drop this patch for 20.11.

Since we are looking to start adding in checks for features into the
example makefiles, I'd go with continuing the policy of just shipping them
all [1]. Over time we can update the makefiles to start adding proper build
error messages with explanations in cases where examples are missing
dependencies.

Can we perhaps keep the existing pkg-config query lines together in the
existing block, and just add the extra checks for this particular app
afterwards? Having done changes en-mass to the example makefiles a couple
of times, it was made a lot easier by having the exact same lines in each
as much as possible, allowing changes to be made by applying a single
patch-file to each makefile in turn.

[dpdk-dev] [PATCH v3 00/11] Examples compilation fixes

[David Marchand]

I tested external compilation for all possible examples (in my env).
The result is this series.
