wiringpi has a really poor build system wrt cross-compiling and has no
official release. These are the patches needed to cross-compile it in
its latest revision.

This patch set was made hoping it would be merged by upstream. Therefore
it's conservative on the changes. However the feedback was that
"cross-compiling is wrong and you should fork it if you want to do so".

I don't really want to fork it, but I think it's doable to maintain a
patch set like this in buildroot.

We already had a patch that proposed to add this library in July 2013
(search for "Raspberry Pi - WiringPi Library Package" in the mailing
list archives). At the time, the approach of the patch was to
completely replace the package build system by a CMake based one. The
patches were actually smaller than the ones you're proposing here:

 package/Config.in                                 |   1 +
 package/wiringpi/Config.in                        |   8 ++

 package/wiringpi/wiringpi.mk                      |  41 +++++++++

That being said, the big drawback of having a completely different
build system is that everytime we will bump this library, we will need
to do some close analysis to verify that our CMake based build system
is aligned with what the official custom build system is doing. In that
sense, I may in the end prefer your approach that consists in fixing
the build system itself. This way, if it gets changed, then we'll
automatically have these changes, or we will notice through conflicts
that things have changed.

Also, looking at your patches below, only a few of them are in fact
directly related to cross-compilation. Most of them fix various other
issues, and maybe could be upstreamed.

These RasberryPi people are really crazy. That some of them want to
spend hours doing native builds on their RasberryPi is a thing, but
that they force everybody to use those poor practices is really
frustrating.

This one can probably be upstreamed. Or maybe making typos is also part
of the RasberryPi way of doing things? :-)

I don't think we really need this patch in Buildroot.

Is this dependency really needed? What does rpi-userland brings that is
needed for wiringPi?

I continue to be skeptical about the usefulness of such a library. Why
not just use the /sys/class/gpio interface? But well, wiringPi seems to
actually be used by some people, so we should have a package for it.

License is LGPLv3+ it seems

No, this is not possible. Make variables in Buildroot are global, and
we clearly do not want a global PREFIX variable to be defined.

A better solution is probably:

WIRINGPI_MAKE_OPTS = \
	$(TARGET_CONFIGURE_OPTS) \
	PREFIX=/usr

WIRINGPI_DIRS = wiringPi devLib gpio

define WIRINGPI_BUILD_CMDS
	$(foreach d,$(WIRINGPI_DIRS),\
		$(TARGET_MAKE_ENV) $(MAKE) $(WIRINGPI_MAKE_OPTS) -C $(@D)/$(d))
endef

define WIRINGPI_INSTALL_TARGET_CMDS
	$(foreach d,$(WIRINGPI_DIRS),\
		$(TARGET_MAKE_ENV) $(MAKE) $(WIRINGPI_MAKE_OPTS) DESTDIR=$(TARGET_DIR) -C $(@D)/$(d) install)
endef

Also, I'm a bit surprised that it doesn't get installed in the staging
directory (i.e WIRINGPI_INSTALL_STAGING = YES). If it's a library, to
which other applications can get linked to, then it should be installed
to the staging directory as well.

Thanks!

Yes. I did what I did in the hope to merge the patches upstream though
I still think it's a poor handmade build system. From my experience
it's easier to merge patches with some changes to the build system
making it compatible with what it was previously doing rather than
proposing a new build system.

Yeah... I'll remove the ones that are not needed. I've got really
frustrated and surprised about the upstream feedback and sent it as
is.

I sent this patch as is... it was not even reviewed. I think the
wiringpi author has a wrong vision of open source: he publishes the
code and he is the only one to make changes but doesn't accept
contributions.

humn... I've put this dependency because this patch makes sense only
for raspberry. As I can see (I'm not the one that is actually making
use of it) it contains configurations that are specific to the rpi and
make no sense in other platforms.

Is this "depends on" the right way to depend on a certain board.

I agree with you. I don't think it's useful at all. The only reason
I'm adding it is because people are using it (particularly the gpio
command that is part of it).

I didn't notice it probably because the gpio program is the only one
actually using and linking to this library, so it doesn't need the
library in the staging dir.


thanks for reviewing it, I'll send an updated version.

Do you plan to resend new versions of your wiringpi and pi4j patches,
taking into account the reviews that were made early January?

Thanks!

sorry for the delay

I totally lost interest in these 2 packages, partially because of the
upstream reaction. Now I don't have access to a rpi anymore to test
them. I may send again in future, but currently I have no plans.

+Subject: [PATCH 3/8] Do not override build variables from command line
+
+Allow to set DEBUG, CC and PREFIX as arguments to make. This allows us
+to easily set another compiler, prefix, flags and so on. It also stops
+setting DESTDIR, since this shouldn't be touched in the makefile, but
+honoured while installing.

+	  WiringPi is a GPIO access library written in C for the BCM2835
+	  used in the Raspberry Pi.
+
+	  WiringPi includes a command-line utility gpio which can be
+	  used to program and setup the GPIO pins. You can use this to
+	  read and write the pins and even use it to control them from
+	  shell scripts.
