标准C库Glibc发布2.17正式版。2012-12-25 上一个版本是2012-06-26的2.16。

详细改进:Version 2.17

* The following bugs are resolved with this release:

  1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,
  9685, 9914, 10014, 10038, 10114, 10631, 10873, 11438, 11607, 11638, 11741,
  12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679, 13696,
  13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950, 13952,
  13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157, 14166,
  14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298, 14303,

  14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518, 14519,

  14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803, 14805,
  14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833, 14835,
  14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872, 14879,
  14889, 14893, 14898, 14914.

* Optimization of memcpy for MIPS.

* CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
  EMFILE has been fixed (Bugzilla #14889).

* The add-on ports collection is now distributed in the "ports" subdirectory
  of the main GNU C Library distribution, rather than separately.

* Port to ARM AArch64 contributed by Linaro.

* Support for STT_GNU_IFUNC symbols added for s390 and s390x.
  Optimized versions of memcpy, memset, and memcmp added for System z10 and
  zEnterprise z196.
  Implemented by Andreas Krebbel.

* The new function secure_getenv allows secure access to the environment,
  returning NULL if running in a SUID/SGID process.  This function replaces
  the internal function __secure_getenv.

* SystemTap static probes have been added into the dynamic linker.
  Implemented by Gary Benson.

* Optimizations of string functions strstr, strcasestr and memmem.
  Implemented by Maxim Kuvyrkov.

* The minimum Linux kernel version that this version of the GNU C Library
  can be used with is 2.6.16.

* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
  powerpc POWER7.  Implemented by Will Schmidt.

* New configure option --disable-nscd builds the C library such that it
  never attempts to contact the Name Service Caching Daemon (nscd).
  New configure option --disable-build-nscd avoids building nscd itself;
  this is the default if --disable-nscd is used.

* Improved support for cross-compilation, including cross-testing and
  bootstrap builds without a previously built glibc.

* Several testsuite tests are now able to test multiple IFUNC variants of an
  interface, rather than just testing the one that would be chooen by
  default.

* New configure options --with-bugurl and --with-pkgversion, for
  distributors to use to embed their bug-reporting and package version
  information in --help and --version output.

* The ttyname and ttyname_r functions on Linux now fall back to searching for
  the tty file descriptor in /dev/pts or /dev if /proc is not available.  This
  allows creation of chroots without the procfs mounted on /proc.

* The `crypt' function now fails if passed salt bytes that violate the
  specification for those values.  On Linux, the `crypt' function will
  consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
  enabled, and fail on encrypted strings using the MD5 or DES algorithm
  when the mode is enabled.

* The `clock_*' suite of functions (declared in <time.h>) is now available
  directly in the main C library.  Previously it was necessary to link with
  -lrt to use these functions.  This change has the effect that a
  single-threaded program that uses a function such as `clock_gettime' (and
  is not linked with -lrt) will no longer implicitly load the pthreads
  library at runtime and so will not suffer the overheads associated with
  multi-thread support in other code such as the C++ runtime library.

* New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
  sat_IN, and szl_PL.

想要升级到2.17可是这个链接没有glibc-ports-2.17下载怎么办?
是不是不需要也是可以的?
问题解决了吗 我make之后没有lib文件夹 怎么回事啊
