It's been 10 days now without any reply from Ulf, so revert r24480+r24481.

It's been 10 days now without any reply from Ulf, so fix it up to what
seems sensible.

Don't make it default yet as uclibc/busybox seems to have some issues
with it.
|
|
For some reason Ulf's export-toolchain stuff breaks the build as the
dependencies target isn't executed and SED isn't set.

Add an option to either generate locales yourself or download the
pregenerated set.

We used to use different gdb configs for internal and external toolchains
because mconf won't source the same file twice. This works, but is kind of
sub optimal, as people forget to keep them in sync.
Fix it to use the same file for both situations by shuffling around the
config options a bit. Should work identical to before (except for the newer
gdb versions available for ext).

* In toolchain/external-toolchain/ext-tool.mk, copy the contents of
the sysroot directory to the staging dir.
* In package/Makefile.in, add a --sysroot CFLAGS pointing to the
staging dir
* Remove the CFLAGS and LDFLAGS definition from
TARGET_CONFIGURE_OPTS. I haven't investigated exactly why, but with
these options, DirectFB fails to build because it cannot find
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, even if DirectFB's Makefile
properly sets -D_GNU_SOURCE.
I have already sent this patch on December, 2nd to the mailing-list,
but got no feedback. So let's commit and see what happens :-)

This reverst the commit 24343, the original state was indeed correct. Blame
goes to my bad sight and too hasty decisions.

Make the ifndef check the actual variable, typo bug.

Add UCLIBC_HAS_{FULL,REENTRANT}_RPC config variables to the defconfig, so
the sed invocation in uclibc.mk can set them to the proper values.

This patch adds uClibc versino 0.9.30 to the list of selectable versions. The
version identification for snapshot is also updated to reflect 0.9.30.

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.

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).

Improve external toolchain support
* Do not put kernel-headers in the dependencies of BASE_TARGETS in
the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
are already supposed to be part of the external toolchain, so
there's no need to download, extract and install them.
* In the configuration system, don't display the kernel headers
version selection list when an external toolchain is selected. This
is implemented by moving the source
"toolchain/kernel-headers/Config.in" inside the if
BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.
* Change the description and help message of the BR2_LARGEFILE,
BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
toolchain/external-toolchain/Config.in. In the case of an external
toolchain, the semantic of these options is not to enable large
file support, IPV6 or RPC (since the toolchain is already compiled,
it has been decided previously). Their semantic is to let Buildroot
know about the characteristics of the external toolchain being
used.
As an improvement, we could guess these values automatically:
- for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
bits/uClibc_config.h in the libc headers directory.
- for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
same file
- for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
the same file
- for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
-- "--with-float=soft"
But I'm not sure how this would be possible, since these values are
used at configuration-time by other configuration options, not only
at build time.
