linuxptp missing.h header implements a replacement clock_nanosleep()
function, which was used when the thread implementation was not NPTL,
because uClibc failed to provide clock_nanosleep() in such
configurations.
However, uClibc-ng has fixed this problem upstream, and has backported
this change in Buildroot in patch
package/uclibc/0002-librt-declare-clock_nanosleep-independent-of-thread-.patch
(the code is upstream and will be part of uClibc-ng 1.0.31). Due to
this, there is now a conflicting definition of clock_nanosleep()
between the C library and the linuxptp missing.h code, which manifests
itself by the following build failure:
missing.h:117:19: error: static declaration of 'clock_nanosleep' follows non-static declaration
static inline int clock_nanosleep(clockid_t clock_id, int flags,
^~~~~~~~~~~~~~~

This commit fixes that by adding a patch that removes the replacement
clock_nanosleep() implementation from the linuxptp code base.

Subject: [PATCH] missing.h: drop clock_nanosleep() replacement
|
|
|
|
Since uClibc-ng commits 68628fe7d463541bf3c33da6b214e63c0cc9feed
|
|
("librt: declare clock_nanosleep not only for NPTL") and
|
|
ddbb03e77ac1a48740688814b82f45c97ee81f37 ("librt: clock_nanosleep
|
|
could be even used without threads"), clock_nanosleep() is always
|
|
provided by uClibc, regardless of the thread implementation (none,
|
|
linuxthreads, nptl). These commits will be part of the upcoming 1.0.31
|
|
release of uClibc-ng.
|
|
|
|
Thanks to this, we can drop the replacement clock_nanosleep()
|
|
implementation added by linuxptp. Without this, linuxptp fails to
|
|
build with:
|
|
|
|
missing.h:117:19: error: static declaration of 'clock_nanosleep' follows non-static declaration
|
|
static inline int clock_nanosleep(clockid_t clock_id, int flags,
|
|
