Hello,

Here are some fixes for various autobuilder failures. Three affecting
Blackfin, one affecting ARC.

The Blackfin toolchain install some libtool .la files, which none of
the other toolchains seem to do, and those .la files confuse libtool
down the road, causing build failures due to incorrect library
paths. As an example, the thrift package has been constantly failing
to build on Blackfin due to this.

To solve this issue, we simply remove the .la files installed by the
toolchain from the staging directory.

Fixes:

  http://autobuild.buildroot.org/results/8ac/8ac073a4e9c3a228dd22d80ea02b9dc3fc739164/

And many similar occurences of the same problem.

This commit adds a patch to mpdecimal that makes it understand
--enable-shared/--disable-shared and --enable-static/--disable-static,
even if mpdecimal isn't using automake/libtool. It allows to build
only the static variant of the mpdecimal library when needed.

Fixes:

+mpdecimal uses autoconf, but not automake or libtool, so this commit
+adds some basic handling of --{enable,disable}-{shared,static}, so
+that building the shared library can be disabled in pure static

The ushare configure script is a custom shell script, and it is not
designed to understand that the library order is important when doing
static linking.

This commit renames the radvd patches to follow the new naming
convention, and reformats them to be Git patches.

Since the patches are renamed, we adjust the comment in the .mk file
explaining why we autoreconf the package.

Modern architectures such as ARC do not provide the sysctl() system
call, since it is deprecated. However, uClibc still installs
<sys/sysctl.h> in such cases, which defeats radvd check for the
availability of sysctl(). This commit adds a patch to radvd which
improves the sysctl() checking.

Fixes:

+Subject: [PATCH 3/3] Improve check of the sysctl() function
+
+Since sysctl is a deprecated system call, new architectures such as
+ARC don't implement it. In such cases, uClibc installs the
+<sys/sysctl.h> header, but dos not implement the sysctl()
+function. This has the annoying side effect of breaking the sysctl
+detection of radvd, which is purely based on the header file being
+present.
+
+To fix this, this commit adds a check based on the existence of the
+sysctl() function.

On 2014-11-23 18:35 +0100, Thomas Petazzoni spake thusly:
> The Blackfin toolchain install some libtool .la files, which none of
> the other toolchains seem to do,

Well, with my crostool-NG toolchains, I have some, for example:

    ./armv6-rpi-linux-gnueabihf/libexec/gcc/armv6-rpi-linux-gnueabihf/4.9.1/liblto_plugin.la
    ./armv6-rpi-linux-gnueabihf/armv6-rpi-linux-gnueabihf/sysroot/lib/libitm.la
    ./armv6-rpi-linux-gnueabihf/armv6-rpi-linux-gnueabihf/sysroot/lib/libstdc++.la
    ./armv6-rpi-linux-gnueabihf/armv6-rpi-linux-gnueabihf/sysroot/lib/libsupc++.la
    ./armv6-rpi-linux-gnueabihf/armv6-rpi-linux-gnueabihf/sysroot/lib/libatomic.la

Or:

    ./x86_64-unknown-linux-uclibc/libexec/gcc/x86_64-unknown-linux-uclibc/4.9.1/liblto_plugin.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libitm.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libvtv.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libstdc++.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libsupc++.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libcilkrts.la
    ./x86_64-unknown-linux-uclibc/x86_64-unknown-linux-uclibc/sysroot/lib/libatomic.la

So, I'm not so sure...

Regards,
Yann E. MORIN.

What do they contain?

At least, with the Blackfin toolchain, for some reason, libtool find it
smart to append the Buildroot sysroot path with the libdir value found
in the .la file.

Thanks,
