[Buildroot] [PATCH 1/3] ncurses: get the post staging installation hook called properly

[Thomas Petazzoni]

There was a typo in the name of the variable to register the hook,
which prevent the hook from actually being called.

[Buildroot] [PATCH 2/3] ncurses: bump to 5.9

[Thomas Petazzoni]

Bumping to 5.9 has two nice side-effects:

 * It builds fine on noMMU architectures such as Blackfin, which will
   fix build failures like
   http://autobuild.buildroot.org/results/cf3e6a95c82b60d63da041293db576a8f21f9136/build-end.log.

 * It installs a pkg-config file, which will allow gpsd to find
   ncurses properly, without the need to use ncurses5-config, which
   means we can get rid of one of our gpsd patches. Thanks to Mike
   Frysinger for pointing the new --enable-pc-files option.

After this bump, I build tested a large number of the ncurses reverse
dependencies we have in Buildroot, and they all built fine.

+Change handling of PKG_CONFIG_LIBDIR
+
+When PKG_CONFIG_LIBDIR was unset in the environment, the configure
+script was deducing the PKG_CONFIG_LIBDIR from the location of the
+pkg-config binary, which doesn't make a lot of sense, and isn't done
+by other autotools based packages.
+
+Also, the configure script was checking that the directory really
+exists. This forced to create the directory *and* provide an absolute
+path in PKG_CONFIG_LIBDIR, which didn't play well with the fact that
+at installation time, PKG_CONFIG_LIBDIR is suffixed to DESTDIR, which
+means that we got two times the staging directory location.
+
+This patch fixes both of those issues. Also, since ncurses uses a fork
+of autoconf 2.13, we can't simply use _AUTORECONF=YES, so we also fix
+the configure script in this patch.

[Buildroot] [PATCH 3/3] gpsd: remove patch to handle ncurses5-config custom location

[Thomas Petazzoni]

Now that ncurses has been bumped to 5.9, it installs .pc files for
pkg-config, which allows gpsd to find it properly without the need to
specify a custom location for ncurses5-config.

Since gpsd now uses pkg-config to find the ncurses library, we also
add host-pkg-config in the dependencies.

Nack.
The version bump to 5.8 and 5.9 had issues in the past and still has.
It may compile just fine but it segfaults miserably in a target, chroot
or qemu image.
Simple test, i586 target with external toolchain, build less and see.
Regards.

Yes, I just did some runtime testing, and also faced segfaults. Now
that you say it, I also remember what you said.

There must something odd: both Yocto and PTXdist are using ncurses 5.9,
so I presume it works for them. So it's not as simple as
"cross-compilation breaks ncurses 5.9", it's something more subtle than
that.

Yes, i agree it's pretty much some little thing.
I did some tests in the past and it doesn't seem to be configure options
related (didn't try everything around, just what would be more obvious
to cause such a failure).
Yet OpenWRT, which is BR's closest relative, still uses 5.7, maybe they
didn't care about bumping it or hit the same issue.
I'll give it another shot later today.
Regards.

I indeed just talked to Florian Fainelli on IRC (he is an OpenWRT
developer), and he remembers hearing issues about ncurses 5.9, and
those issues being the reason to stick to 5.7 for now.

But still, PTXdist and OE have it. So it should work somehow. And they
don't seem to have bizarre patches.

  Does the segfault issue also occur on arm or powerpc?  Neither PTXdist
nor OE is a big i386 user, so maybe they just didn't notice the problem.

Gentoo has 5.9 as stable for all major architectures, i'm pretty sure it
works so it's something we're doing different/wrong.

Yesterday, I tried on ARM Cortex-A8 within the Qemu VExpress emulation
(using Linaro toolchain), and it segfaulted. I haven't tried on real
hardware though, so could always be a Qemu problem, or a toolchain
problem.

I've tried on real hardware (arm, powerpc) and it's the same issue.
I'll do some tests on a chroot (i586 or x86_64) to try track it down
since it fails too, at least for i586.
Regards.
