Note that the external toolchain always defaulted to use a glibc-based
toolchain. Steven should be notified on such a change since (IIRC) it
was him who added the external-toolchain thing..

He afaiks reads this list as well, and it's just defaults, so no big
deal. BR2_TOOLCHAIN_EXTERNAL_LIBS, BR2_TOOLCHAIN_EXTERNAL_PATH and
BR2_TOOLCHAIN_EXTERNAL_PREFIX weren't set to anything before, so glibc
users have to configure it anyway.

We might as well default to something that is right away usable for
buildroot users.

It would be nice if you would list example values in the help-text for a
few libc's then (i did not look if you already do this).

I've set this to "$(BR2_STAGING_DIR)/usr" here, which might be a good
default?

Probably not a useful default, given that all the examples have -gnu etc
after them? Mine is armeb-linux-uclibcgnu here; again you can probably
construct something like "$(ARCH)-$(BR2_GNU_TARGET_SUFFIX)".

You think so? I wouldn't expect having buildroot install package stuff
together with the (potentially read only) external toolchain would be
a common setup.

Don't you have an armeb-linux symlink? For the stuff I compile (arm,
i386, ppc) there's symlinks from the arm-linux-uclibc-<whatever> to
arm-linux-<whatever>.

Well I've got one board ("tools", in local/tools/tools.config) to build
the toolchain which I then use as external toolchain to build several
other boards (all armeb-linux-uclibcgnu). So my toolchain lives in the
staging directory in the same tree.

This makes for a nice path-independent setup too.. other developers at
my company can check out the tree and build everything (including the
toolchain first) into any path they like.

So if this isn't a common approach then maybe it isn't a good default
after all.

Probably, I'll have to check tomorrow.

So they all put libraries / headers in the same staging_dir? Doesn't
that give problems with packages detecting optional stuff at compile
time that might not be available for a specific variant (E.G. one
variant has expat, and another doesn't - Some configure script checks
for expat and finds it in staging_dir even though it isn't going to be
there at runtime).

The same with the packages offering different versions.

I think a more common setup would be to install the toolchain
somewhere common (/opt/<whatever>) and then have multiple boards using
the same toolchain/c library but potentially different set of
packages(-versions) and their own staging_dir.

If i understand correctly what you are talking about then this is
exactly the purpose of that PROJECT thing, fwiw.

Me? No, the project stuff is (afaik atleast) just about compiling the
configurable packages under project_build_* instead of build_*, so you
can reuse a single working directory / staging_dir for multiple
projects. It has the same drawbacks as what I listed above.

It does sound pretty much what Hamish is doing though.

Yes.

Good point. So far all my boards are very similar so this hasn't been a
problem, but that won't always be the case.

IMHO this is a flaw of the project support - everything should be built
into a project-specific directory. Currently only the kernel and busybox
are built in project_build_$arch.

How would everyone react to a patch which redefines BUILD_DIR to match
PROJECT_BUILD_DIR, ie each project would have
project_build_$arch/$project/staging_dir etc?

I think Ulf commented in the past that he doesn't want to waste the time
spent compiling each package for each board separately, but that seems
to be the only way to do it correctly.

No, then you might as well use several buildroot trees.

You have to be aware of the limitations, that's for sure.
There are a number of packages which can only be built one way
and they can reside in build_<arch>, packages which have different
options needs to be built in project_build_<arch>

Maybe there's a solution in between. Put packages that really can only
be built one way under build_, and all other packages under
project_build, and then have STAGING_DIR under project_build as well
(with some logic to copy/symlink in the toolchain stuff). Then each
variant could use different versions / configurations of the packages,
and we would still only compile the stuff under build_ once (per
version).

External toolchain C++ cross-compiler fix

External toolchain C++ cross-compiler fix

package/Makefile.in resets CXX to "" in TARGET_CONFIGURE_OPTS if
BR2_GCC_CROSS_CXX is not set to 'y'. However, when using an external
toolchain, BR2_GCC_CROSS_CXX is not set even if the toolchain has a
C++ cross-compiler.

This patch adds a new BR2_GCC_CROSS_CXX option in the external
toolchain configuration menu, so that just like BR2_INET_RPC,
BR2_INET_IPV6 and the others, it can be set according to the external
toolchain configuration.

More external toolchain fixes

Fix issues with binary external toolchains

Fix two problems encountered while using an external binary toolchain
generated by crosstool-ng:

 - Don't remove the ending / in LIB_DIR, otherwise find $LIB_DIR
   -maxdepth 1 doesn't find any file in the case LIB_DIR is a symbolic
   link and not a directory.

   For some reason, find -maxdepth 1 doesn't have the same behaviour
   on directories and symbolic links. Demonstration:

   $ mkdir foobar
   $ touch foobar/t1
   $ touch foobar/t2
   $ ln -s foobar barfoo
   $ find foobar -maxdepth 1 -name 't*'
   foobar/t1
   foobar/t2
   $ find barfoo -maxdepth 1 -name 't*'
   $ find barfoo/ -maxdepth 1 -name 't*'
   barfoo/t1
   barfoo/t2

 * Make sure the libraries are writable, otherwise the strip operation
   might fail. The library files may not be writable if the toolchain
   is not writable (which may happen if one wants to prevent anyone
   from overwriting the toolchain, which is done by crosstool-ng, for
   example).
