If your applications require pthreads, answer Y.

- If you want to compile uClibc with NPTL support, then answer Y.
-
- IMPORTANT NOTE! NPTL requires a Linux 2.6 kernel, binutils
- at least version 2.16 and GCC with at least version 4.1.0. NPTL
- will not work with older versions of any above sources. If you
- ignore any of these guidelines, you do so at your own risk. Do
- not ask for help on any of the development mailing lists.

- !!!! WARNING !!!! BIG FAT WARNING !!!! REALLY BIG FAT WARNING !!!!
-
- This is experimental code and at times it may not even build and
- even if it does it might decide to do random damage. This code is
- potentially hazardous to your health and sanity. It will remain
- that way until further notice at which point this notice will
- disappear. Thank you for your support and for not smoking.

-Now that the Linux kernel is once again able to run all the tests we
-have and since glibc 2.3 was released it was time for a new code drop.
-I've uploaded the second code drop for the Native POSIX Thread
-Library:
-
- ftp://people.redhat.com/drepper/nptl/nptl-0.2.tar.bz2
-
-You need
-
-- the latest of Linus' kernel from BitKeeper (or 2.5.41 when it
- is released);
-
-- glibc 2.3
-
-- the very latest in tools such as
-
- + gcc either from the current development branch or the gcc 3.2
- from Red Hat Linux 8;
-
- + binutils preferrably from CVS, from H.J. Lu's latest release for
- Linux, or from RHL 8.
-
-
-Compiling glibc should proceed smoothly. But there are a number of
-tests which fail, mostly because some functionality is missing in
-glibc. Ignore those errors. It is only important that all tests in
-nptl/ are passing. Run
-
- make subdirs=nptl check
-
-to run all thread tests.
-
-
-This version features several improvements:
-
-- all APIs are now implemented;
-
-- fork handling has been improved; stacks in the child are freed;
- atfork handlers are removed if they were registered from a module
- which gets unloaded.
-
-- pthread_tryjoin_np and pthread_timedjoin_np are implemented
-
-- TSD handling corrected and optimized.
-
-- many more tests which also test the underlying kernel implementation.
-
-- the build infrastructure has been implemented so that the DSO and
- archives are built in usable form and with correct named.
-
-- libthread_db has been implemented. This is the library which is
- needed by all program which need to get access to internals of
- libpthread (mainly debuggers).
-
-- the CPU clock functions are implemented
-
-
-
-The white paper hasn't yet been updated. It's still available at
-
- http://people.redhat.com/drepper/nptl-design.pdf
-
-
-This release should be ready for some serious testing. I know it is
-hard to compile which I why I'm looking into providing binary RPMs.
-They can be used on non-critical systems. I'll only be able to
-provide binaries for RHL8 based systems, though, and the kernel still
-must be installed separately.
-
-
-The next steps will include:
-
-- write more tests and fix the bugs which are discovered this way
-
-- update the white paper
-
-- write and run more performance tests
-
-- port to IA-64
-
-
-Interested parties are once again invited to join the mailing we
-created:
