[Buildroot] External toolchain improvements

[Buildroot] External toolchain improvements

[Thomas Petazzoni]

Hi,

About one month ago, I posted two patches that try to improve external
toolchain support. I've rebased these patches and pushed them to a
public Git repository, in a branch called external-toolchain :

 http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=external-toolchain

I'm asking for a review of these patches (is the feature worthwhile, is
it well implemented, etc.), and maybe inclusion of these patches if
they are suitable.

Also, please don't hesitate to report any issue with the patches: I'm
not yet completely familiar with Git, so I may have done mistakes when
generating/publishing the patches.

Thanks,

Thomas

[Buildroot] External toolchain improvements

[Lionel Landwerlin]

Hi Thomas,

I'm interested by your patches, I'm using a STLinux external toolchain
(Linux for SH4 SetTop Boxes).

The problem is that copying only libraries is not enough to build even a
simple program like this one :

int main (void) { return 0; }

With my current toolchain, I also need :

      * crt1.o crti.o crtn.o
      * All headers from the libc & linux

After that, I also have problems with packages using pkg-config.
Pkg-config returns paths relatives to the build directory ( -L/usr/lib
for example). This tries to link with

We probably need a double --sysroot parameter to look first where the
toolchain is installed and then in the given sysroot path.

Hi Lionel,

Ok. Nice to see interest in external toolchain support, which is still
experimental, as you saw.

I'm not sure which Buildroot version you're using, but 2009.05 and
current Git don't only copy the libraries. Here is what we do :

 1) Copy + strip the libraries to the target space
    (project_build_ARCH/PROJECT/root). Only the files needed for
    execution need to be copied to the target space.

 2) Copy the full sysroot to the staging space (build_ARCH/staging_dir).

This is done in toolchain/external-toolchain/ext-took.mk.

In current Buildroot, all these are copied to the staging directory. In
an example build, I have :

$ find . -name '*crt*'
./build_arm/staging_dir/usr/lib/Scrt1.o
./build_arm/staging_dir/usr/lib/crt1.o
./build_arm/staging_dir/usr/lib/crti.o
./build_arm/staging_dir/usr/lib/crtn.o

$ find build_arm/staging_dir/ -name '*.h' | head -5
build_arm/staging_dir/usr/include/neteconet/ec.h
build_arm/staging_dir/usr/include/strings.h
build_arm/staging_dir/usr/include/ttyent.h
build_arm/staging_dir/usr/include/pty.h
build_arm/staging_dir/usr/include/mntent.h

This should theorically not happen since we should pass --sysroot to
every gcc/ld compilation step, and therefore all paths should be
interpreted relative to the sysroot (which is in fact the staging dir).

Could you give more details about what you're doing :

 * Buildroot version
 * Buildroot .config file
 * Error messages
 * External toolchain used

Thanks !

Ok, I had another look at the ext-tool.mk makefile, and the sysroot dir
is not copied because of the locale...

This current command to get the sysroot dir is :

SYSROOT_DIR=`$(TARGET_CC) -v 2>&1 | grep ^Configured | tr " " "\n" | grep -- "--with-sysroot" | cut -f2 -d=`;

which call (in my case) sh4-linux-gcc using the default locale and as my
email address could suggest, my current locale is fr_FR.UTF-8. So grep
^Configured just fails.

Please apply the attached patch to your external-toolchain branch.

Your external-toolchain branch

>  * Buildroot .config file

Attached

>  * Error messages

I will try to retry with the fix on the locale first.

>  * External toolchain used

SH4 toolchain from STLinux-2.3 distribution, available freely at the
stlinux.com website.

Ok, thanks for patch. I should probably add a little bit of error
checking in this external toolchain thing.

Which doesn't exist anymore since it has been merged in the official
Buildroot :-)

But ok, fine, I know what you're using.

For sure if Buildroot didn't properly copy the sysroot to the staging
dir, the rest of the compilation could not work.

That said, your configuration file enables a relatively large set of
packages that I haven't tested with the external toolchain
configuration. Most if not all of the packages using the
Makefile.autotools.in machinery should build flawlessly, but the
packages using their own stuff in the .mk might break. Don't hesitate
to report the breakage with the associated error messages (or the full
build output), it's usually relatively easy to fix.

Thanks!

I'm now up to date on the last git.

Ok, so I just rerun buildroot again with full staging directory copied
from the external toolchain, and I got that when compiling glib2 :

As you can see, there is a -L/usr/lib and -rpath /usr/lib.

Arf, libtool crap.

Can you try with

LIBGLIB2_LIBTOOL_PATCH = YES
LIBGLIB2_AUTORECONF = YES

in package/libglib2/libglib2.mk ?

This will try to fix ltmain.sh to workaround cross-compiling issues.

The patch can not be applied cleanly. I finished it at hand.

Then the reconfiguration of the build scripts fails too :

This is strange, because autoreconf uses automake from the host instead
of /home/djdeath/src/buildroot/buildroot/build_sh4/host_dir/usr/bin/automake, just like it's done for autoheader/autoconf/aclocal.

I finally succeeded in building glib2...
I had to patch the configure.in and the gtk-doc.make files against a
problem when reconfiguring the scripts.

GTK_DOC seems to be the main problem.

I successfully built the following packages :

atk-1.22.0
directfb-1.4.0
fontconfig-2.6.0
libungif-4.1.4
perl-5.8.8
zlib-1.2.3
cairo-1.6.4
dbus-glib-0.80
expat-2.0.1
freetype-2.3.9
jpeg-6b
libpng-1.2.35
libxml2-2.6.32
pixman-0.10.0
dbus-1.2.12
gettext-0.16.1
libglib2-2.20.1

I'm now stuck with a dbus-glib build error :

make[7]: Entering directory `/home/djdeath/src/buildroot/buildroot/build_sh4/dbus-glib-0.80/dbus/examples'

make[7]: *** [example-service.o] Error 1

It's a bit late, so I will check that later this week. Any suggestion is
welcome.

Except patches I've done for the GTK_DOC stuff in glib (I mostly
commented lines), you can find other patches in attachment.

Just a word about the choice to put the EXTERNAL_LIBS variable in
toolchain/external-toolchain/ext-tool.mk. I don't think it's a good
choice. For example, my current toolchain includes a glibc version 2.6.
This make the ld-linux loader name /lib/ld-linux.so.2 instead
of /lib/ld-linux.so.3.

Modifying an enormous variable inside kconfig is painful, but I think
it's better to let this variable configurable rather than encourage the
buildroot user to modify an unfriendly makefile
(toolchain/external-toolchain/ext-tool.mk).

This is also something I've discovered recently. I'd like to spend some
time to see if it's still possible to auto-detect the version of the
libraries to copy. If it doesn't work, then I fallback to the previous
solution, which I don't find really nice.

Sincerly,

Thomas

I just successed in building webkit on top of directfb with an external
toolchain. We should also think to copy the libstdc++ files when
selected from the config file.
