[Buildroot] [PATCH v2 1/3] package/make: add host variant

[Romain Naour]

Add host variant for make package since glibc 2.28 now require
GNU Make >= 4.0 [1].

We have to ceate gnumake and gmake symlinks to GNU make generated by
Buildroot for the host. Otherwise the one provided by the host system
can be used instead.

For example, the glibc build system is looking for gnumake and gmake
before make. See [2].

[Buildroot] [PATCH v2 2/3] dependencies: host-make version check

[Romain Naour]

The host make program is already checked by dependencies.sh but we
want to check the version number even if Buildroot is able to use
GNU make >= 3.81 but some packages may require a more recent version.

For example, since version 2.28 [1], glibc requires GNU Make >= 4.0.

For packages requiring make >= 4.0, the package makefile must use:
<PKG>_DEPENDENCIES = $(BR2_MAKE_HOST_DEPENDENCY) ...
<PKG>_MAKE = $(BR2_MAKE)

BR2_MAKE1 is also available if needed.

[Buildroot] [PATCH v2 3/3] package/glibc: allow to specify host-make

[Romain Naour]

Use host-make package if GNU make from the host machine is too old.

Use the newly introduced BR2_MAKE_HOST_DEPENDENCY and BR2_MAKE to
provide respectively, host-make dependency and the path to the GNU
make binary to use for building glibc.

I plan to give this a test tomorrow.  We have been close to sending
something similar because of a Make 3 vs 4 issue across vintages of
builds we've been supporting.  I wonder if there is any interest
picking this one back into the LTS?

 Is it needed for anything else than glibc 2.28 then?

Rather than parsing version strings, I've had good success with using sort -V:

if [ "$(printf '%s\n' "${minver}" "${makever}" | sort -V | head -n 1)"
!= "${minver}" ]; then
  exit 1
fi

sort -V was added to GNU sort in coreutils 7.0 released 2008-10-05

[Buildroot] [PATCH v2 1/3] package/make: add host variant

Hello,

If you're talking about the issue that Sam Voss was discussing on IRC,
then it's different. Your issue was that your host machine is using
make >= 4.0, but some of your funky packages don't like that and would
need make < 4.0 to build.

This is not handled by Romain's series@all, which handles the
opposite situation: packages that need make >= 4.0, but the host has
make < 4.0.

Best regards,

Thomas

Yep, Sam was discussing handling older kernel / buildroot versions vs
versions of Make.

Romain's series covers compatibility on some of our older build
machines until we get them refreshed.
