14 From the uClibc config option help:
15 There are two versions of linuxthreads. The older (stable) version
16 has been in uClibc for quite a long time but hasn't seen too many
17 updates other than bugfixes.
19 config LIBC_UCLIBC_LNXTHRD_NEW
23 From the uClibc config option help:
24 The new version has not been tested much, and lacks ports for arches
25 which glibc does not support (like bfin/frv/etc...), but is based on
26 the latest code from glibc, so it may be the only choice for the
27 newer ports (like alpha/amd64/64bit arches and hppa).

45 Say y if you want uClibc to support localisation.
47 Note that seems to be broken on recent uClibc releases.

51 prompt "Use pregen locales"
52 depends on LIBC_UCLIBC_LOCALES
55 If you see issues with using pre-generated locales data,
56 you can try switching this off.
58 If so, please report the issue, so we can default this
59 to off if too many people complain.
61 config LIBC_UCLIBC_WCHAR
63 prompt "Add support for WCHAR"
65 Say y if you want uClibc to support WCHAR.
67 Maybe this is needed, if you're building a C++-Compiler
69 config LIBC_UCLIBC_FENV
71 prompt "Add support for fenv.h"
74 fenv.h provides functions to control the floating point environment,
75 such as rounding mode, exceptions...
77 For some architectures, fenv.h is incomplete, so is not installed
78 by default. x86 is known to have a rather complete fenv.h, so it is
79 installed by default only for x86.
81 If you need fenv.h on other architectures, say 'y' here, but you may
82 encounter some issues.
