The current computation of REAL_GNU_TARGET_NAME is incorrect for
non-ARM glibc platforms because it generates something such as
mipsel-unknown-linux- as the REAL_GNU_TARGET_NAME.
So we correct this by :
* Adding "gnu" in the suffix when glibc is used, so that in the
previous case we will have mipsel-unknown-linux-gnu
* Improving the ARM_EABI code to correctly append "eabi" when glibc
is selected, so that we have arm-unknown-linux-gnueabi, and to
append "gnueabi" when uclibc is selected, so that we have
arm-unknown-linux-uclibcgnueabi. The little trick here is that LIBC
and ABI aren't completely orthogonal on ARM.
This fixes problems such as :
checking host system type... Invalid configuration
`mipsel-unknown-linux-': machine `mipsel-unknown-linux' not recognized

Commit ed0d45fdd (Choose host/target ldconfig based on availability)
added a runtime check for a cross-ldconfig being available.
Unfortunately this checks runs too early (at package/Makefile.in parsing
time), so it always fails when using an internal toolchain as ldconfig
isn't built yet.
Fix it by moving the check to the only place it is used (target-finalize).

When building packages for the host, the *_FOR_BUILD and *_FOR_TARGET
variables are not needed.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
We build host tools installed in $(HOST_DIR)/usr/bin, and some of them
rely on host libraries in $(HOST_DIR)/usr/lib. So when these host
tools are executed, they need to find the host libraries, which are
not installed in a default location.
In c1b6242fdc we tried to use
LD_LIBRARY_PATH when building target packages to solve this
problem. Unfortunately, LD_LIBRARY_PATH is not only used to find
libraries at run-time, but also at compile time. So it leads the build
of some packages, such as icu, to fail.
Therefore, in 0d1830b07d, we reverted
the LD_LIBRARY_PATH idea.
The other option to solve this problem was to hardcode a RPATH value
in the host binaries that would reference the location of host
libraries. We added this -Wl,-rpath option to HOST_CFLAGS in
6b939d40f6. Unfortunately, this caused
problems when building binutils, as reported in bug 1789 so this
change was reverted in e1a7d916e9.
Then, we tried to use -Wl,-rpath in HOST_LDFLAGS, but it was causing
problems with fakeroot not recognizing 'ld' as the GNU linker, since
the -Wl,-rpath cannot be understood by 'ld' directly, only by 'gcc'.
This commit is a new attempt at using HOST_LDFLAGS, but in this case
we modified the definition of HOST_LD to *not* contain
HOST_LDFLAGS. LDFLAGS are being set separatly. It solved the fakeroot
issue and was tested against nearly 300 packages of Buildroot.

For the detection of the ARCH_SYSROOT_DIR (which contains the C
library variant specific to the compiler flags), we used to pass only
the -march argument instead of the full TARGET_CFLAGS. This was done
because TARGET_CFLAGS contains --sysroot, and we don't want to tell
here the compiler which sysroot to use, because we're specifically
asking the compiler where the *normal* arch sysroot directory is.
Unfortunately, there are some multilib variants that aren't decided
only based on -march, but also on -msoft-float or other compiler
flags. Therefore, we take the opposite approach: pass the full
TARGET_CFLAGS, from which we have stripped the --sysroot option.
For example, this allows a PowerPC CodeSourcery toolchain, on which
we're using the soft-float multilib variant, to work properly as an
external toolchain.

In order to solve issues of libtool trying to link target components

Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
In c1b6242fdc, we added
$(HOST_DIR)/usr/lib to LD_LIBRARY_PATH when building target packages,
because the build of target packages sometimes require host tools
installed in $(HOST_DIR)/usr/bin which themselves require host
libaries installed in $(HOST_DIR)/usr/lib.
Unfortunately, this solution didn't work, as libtool then tried to
link target binaries against host libraries. So $(HOST_DIR)/usr/lib
got removed from LD_LIBRARY_PATH in
0d1830b07d.
However, this meant that we went back to the previous situation, in
which host tools used during compilation of target components might
require host libraries. An example :
make[2]: Entering directory `/home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/build/xfont_font-adobe-100dpi-1.0.1'

Therefore, we try another solution: make sure that host binaries are
linked with an -rpath option, so that $(HOST_DIR)/usr/lib doesn't need
to be in LD_LIBRARY_PATH for them to find their libraries.

Some packages like icu requires to be compiled against the host system
first to be able to compile against the target. This is due to the
usage of self generated binaries by the package to build itself. When
the generated tools also depends on generated libraries it is required
to add the path to these libraries in the library path
(LD_LIBRARY_PATH) especially for the configure step.
Adding $(HOST_DIR)/usr/lib to LD_LIBRARY_PATH for target compilation
might break the link step by mixing host libraries and target
binaries.

- have the toolchain_buildroot case always appear first

In an attempt to disable the compilation and installation of

Unfortunately, --without-html-dir doesn't work. It leads libglib2
./configure script to think that HTML_DIR is "no", which leads to the
installation of the documentation in $(STAGING_DIR)no (yes, with the
"no" suffix at the end). The issue is that --with-html-dir is not an

Move stamp (dependency) files outside the (version specific) source
directories, so other packages can hardcode dependencies on them instead
of having to use <PACKAGE>_VERSION variables.
This is important as the variables in the make rules are evaluated when
the rules is seen, which might be before the dependent makefile is parsed
(and hence <PACKAGE>_VERSION variable is known, screwing up stuff.
The downside of this is that the package isn't automatically rebuilt
when the version changes (E.G. by a svn update) and you now also have to
remove the stamp files next to $(BUILD_DIR)/<PACKAGE>-* to force a rebuild.
This matches upstream tarball, doesn't screw up existing .config's with
BR2_PACKAGE_PKGCONFIG and makes sure the patch gets applied for target
compilation.
gcc < 4.2.0 doesn't support -Wno-overlength-stings, but gcc-4.3.x configure
fails to detect that, breaking the build.
Work around it by detecting the host gcc version (and store in HOSTCC_VERSION)
and set the proper configure variables for gcc < 4.2.0.
The VFP is only available for a few ARM CPUs at the moment,
so this breaks the liboil build.
A patch is available upstream which only enables "-mfpu=vfp"
if "--enable-vfp" is given to "configure".
Autotools needs to be run for liboil for this to take effect.
A new configuration BR2_VFP_FLOAT is added to allow enabling vfp.
If this is "yes", then "-mfpu=vfp" is added to CFLAGS.
TARGET_PATH didn't contain $(STAGING_DIR)/usr/bin, which means that
programs installed in $(STAGING_DIR)/usr/bin were not considered for
execution during Buildroot build process. This was a problem with host

The following changes allow for use of a central configure cache
file. This speeds up configuration of packages.
Its use is configurable at the top level (BR2_CONFIG_CACHE - default n).
Old style makefiles can use it if they use the following MACRO in makefiles:
$(AUTO_CONFIGURE_TARGET) see my change to directfb.mk.
New style Autotools.in will use it if you set the global option.
However you can enable the global option and on a per package overrule it by doing
the following: $(PKGNAME)_USE_CONFIG_CACHE = NO see fontconfig.mk for an example
of this.
Finally I have removed a few config variable settings which indicated no CXX compiler
as this is wrong and breaks the build when using this central cache.

I would appreciate feedback on this change (I have been testing for 2-3 weeks)
But I can never test all cases! If you enable the BR2_CONFIG_CACHE option some
Makefile.autotools.in based packages may now break - I cannot build them all.
In this case you may need to remove config options that are being hardcoded all
over the place (like gtk saying we have 2 CXX compiler) or disable the use
of CONFIG CACHE file like I have done in fontconfig.

This patch is a new version of a patch already sent several times on
the mailing-list, committed and reverted a few times by Daniel Laird,
due to several imperfections. This version is a new try at finding a
solution that works for everybody. Hopefully it'll work :-)
The original problem is that external toolchain builds failed because
packages couldn't find their dependent libraries at configure time and
could not be linked with them. To fix these two problems, two things
are added:
* The TARGET_LDFLAGS variable was exposed as LDFLAGS at ./configure
time thanks to TARGET_CONFIGURE_OPTS. The TARGET_LDFLAGS variable
contains -L options with the path in the STAGING_DIR for the
libraries. It allows ./configure scripts to properly compile the
small test programs testing whether a dependency is properly
installed.
* The TARGET_CFLAGS contains a new -Wl,--rpath-link option for both
$(STAGING_DIR)/lib and $(STAGING_DIR)/usr/lib. It allows library
depending on other libraries to link properly. The TARGET_CFLAGS is
exposed as CFLAGS in TARGET_CONFIGURE_OPTS.
This new version fixes a problem encountered by hartleys
<hartleys@visionengravers.com> when building the kernel. The problem
was that the -Wl,--rpath-link options were added to LDFLAGS, while
there are options for the C compiler, not the ld linker. Moving them
to CFLAGS seems to fix the issue.
