First patch is not needed since version 1.67.0 and
90dd8146fb
Indeed, since this bump, the patch is wrongly patching
virtual string_type format(double value,size_t &code_points) const
instead of:
virtual string_type format(int64_t value,size_t &code_points) const

Use eventfd() function with uClibc
|
|
|
|
The Boost eventfd code either directly makes the eventfd system call
|
|
using __NR_eventfd (when __GLIBC_MINOR is less than 8), or otherwise
|
|
uses the eventfd() function provided by the C library.
|
|
|
|
However, since uClibc pretends to be glibc 2.2, the Boost eventfd code
|
|
directly uses the system call. While it works fine on most
|
|
architectures, it doesn't on ARC since __NR_eventfd is not defined on
|
|
this architecture. However, eventfd() is properly implemented.
|
|
|
|
So, this patch adjusts the logic used by Boost to consider uClibc as a
|
|
C library providing the eventfd() function.
