*	package/glibc: switch to using the maintenance branch	Yann E. MORIN	2017-10-29	1	-56/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	glibc upstream has ruled against doing regular point-releases, but they do have a lot of interesting and important fixes for regressions and security. Backporting each patch, or cherry-picking individual patches is off limits for us, so we just switch to using the currently-latest HEAD of the maintenance branch instead. The version number is obtained with: $ git describe --match 'glibc-*' --abbrev=40 origin/release/2.26/master The alternative options were: - download the tarball from the git tree --> does not work; not an option - download the 2.26 tarball, and bundle the individual patches in Buildroot --> maintenance of patches is a burden; not an option - download the 2.26 tarball, maintain the list of patches to download from the git tree --> not an option for the same reason So we end up just doing a git clone. The git tree is today about ten times the size of the tarball, so a rough estimate makes it at about ten times the download time. Also upstream doesn't officially provide an https download location [1]. There is one but it's not reliable, sometimes the connection time out and end-up with a corrupted git repo: fatal: unable to access 'https://sourceware.org/git/glibc.git/': Failed to connect to sourceware.org port 443: Connection timed out So switch to using a git mirror from github which is updated once a day [2]. This allow at the same time to clone the git repository faster. Note: The glibc 2.26 patches are not kept for the arc toolchain since they are fixing an issue with the new float128 support introduced in x86, x86_64 and powerpc64le.

All these issues are now fixed in the glibc 2.26 stable branch. Backport patches from glibc 2.26 stable branch related to bug 21930. Take all patches listed in this bug report in order to have all fix for this issue [1] [2]. Fixes gnuradio build: [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp: In function ‘std::size_t boost::hash_detail::float_hash_value(T)’: [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: expected primary-expression before ‘float’ switch (fpclassify(v)) ^ [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: expected primary-expression before ‘long’ switch (fpclassify(v)) ^ [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: found ‘:’ in nested-name-specifier, expected ‘::’ switch (fpclassify(v)) ^ [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: ‘_Float128’ is not a class or namespace switch (fpclassify(v)) ^ [...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: ‘_Generic’ was not declared in this scope switch (fpclassify(v)) ^ Also backport fix for glibc bug 22146. Without this patch some C++ applications (jsoncpp, mesa3d and kodi) fail to build due to an issue while building the toolchain. A test in the libstdc++ configure script fail when -Os and float128 are used. See the bug report for details [3].
