[Buildroot] [PATCH v3 0/3] fix pulseview build failures

[Bartosz Golaszewski]

This series fixes pulseview build failures which have been observed
on many autobuilders. They have been caused by doxygen not being present
on host machines.

The first patch adds doxygen host package. The second makes libsigrok
depend on it when C++ bindings are selected. When that is fixed we
can finally revert the patch marking libsigrokcxx as broken.

v3:
- *really* use host-generic-package instead of host-autotools-package
- drop unneeded parenthesis around make invocations
- add a comment about the reason for not using host-autotools-package

v2:

I've applied, but I had to do some further changes, because it was
still not building properly:

    [Thomas:
     - add missing dependencies on host-flex and host-bison
     - add $(HOST_MAKE_ENV) to the configure, build and install steps, to
       make sure that the doxygen build system can find flex and bison.]

You don't catch such issues because you build on a development system
that has lots of development tools already installed, while the
autobuilders are testing using minimal chroots having only the strictly
required Buildroot dependencies installed.

Thanks!

I've applied, after adding host-python (or host-python3) in the
dependencies when building the C++ bindings. Otherwise, the creation of
the C++ bindings fail, due to Python being too old: some autobuilders
only have Python 2.6, while libsigrok requires at least Python 2.7.

Committed with this fixed.

Thanks!

I'll have to start testing buildroot patches in a minimal chrooted
environment then. Thanks for the hint.

Well, it's not strictly mandatory. Usually, it doesn't make such a big
difference, and the minor missing dependencies are found using the
autobuilders. You just had some bad luck with this unexpected doxygen
dependency, with doxygen itself depending on flex and bison, plus
libsigrok depending on python to generated the C++ bindings. This is
rather unusual, so I can't blame you for not having tested things
inside a minimal chroot: our autobuilders are also here to allow us to
save a bit of time when developing the packages, knowing that the
autobuilders will validate a number of things once the packages get
committed.

Thanks!
