Subject: oprofile: fix nanosleep() issue on non-threaded toolchains
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=699c320094885cd0ea765c2a15cba544bf693a70;p=buildroot.git

oprofile: fix nanosleep() issue on non-threaded toolchains

This commit adds a patch to OProfile that ensures <time.h> is included
whenever nanosleep() is used, which fixes a build failure on uClibc
toolchains with no thread support.

Fixes:

+Subject: [PATCH] Include <time.h> for nanosleep()
+
+The nanosleep() function prototype is in <time.h>, so this header file
+should be included whenever nanosleep() is used. Not including it
+causes some issues when building OProfile against a non-thread capable
+version of the uClibc C library, probably because in such situation,
+<time.h> does not get included by another header.
