It currently runs unmodified on GNU Hurd systems and Linux i386, m68k, and alpha systems. Support for Linux PowerPC, MIPS, Sparc, Sparc 64, and Arm will be G
12、libc 2 HOWTO 6.Compiling with the nonprimary libc.2 in version 2.1. In the future support for other architectures and operating systems will be added. On Linux, glibc 2 is used as the libc with major version 6, the successor of the Linux libc 5. It is intended by the Linux libc developers to eventua
13、lly replace libc 5. As of 2.0.6, glibc is considered production quality. Version 2.1 (due out in the near future) will be ready for main stream use along with adding more ports and features. There are three optional addons available for glibc 2: Crypt The UFCcrypt package. It is seperate because of
14、export restrictions. LinuxThreads An implementation of the Posix 1003.1c “pthread“ interface. Locale data Contains the data needed to build the locale data files to use the internationalization features of the glibc. The crypt and LinuxThreads addons are strongly recommended. not using them risks to
15、 be incompatible with the libraries of other systems. (If you do not wish to use them, you must add the option disablesanitychecks when you run configure.) 1.2 About this document. This HOWTO covers installing the glibc 2 library on an existing Linux system. It is tailored for users of Intel based s
16、ystems currently using libc 5, but users of other systems and alternate libraries (such as glibc 1) should be able to use this information by substituting the proper filenames and architecture names in the appropriate places. The latest copy of this HOWTO can be found as part of the Linux Documentation Project or from 1.3 Recent changes in this document. Differences between version 1.6 and 1.5: Fixed the install inst
