gcc48 is broken by configure-timespec.patch — at Initial Version

Reported by: howarth@… Owned by: macports-tickets@…
Priority: Normal Milestone:
Component: ports Version: 2.1.3
Keywords: Cc:
Port: gcc48

Description

Please see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56835. It appears that the unnecessary patch...

https://trac.macports.org/browser/trunk/dports/lang/gcc48/files/libstdc%2B%2B-configure-timespec.patch

is breaking std::promise on darwin.

The alternative fix of http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=192335 was checked in to achieve the goal of using
nanosleep in c++11.

Note that the fix I checked in for gcc 4.8.0 defaults darwin to --enable-libstdcxx-time so neither that option nor your hack needs to be applied.
The g++-fsf-4.8 compiler on fink doesn't fail the test case reported in PR56835 but has nanosleep declared in the object file...

% cd /sw/src/fink.build/gcc48-4.8.0-1000/darwin_objdir/x86_64-apple-darwin12.3.0/libstdc++-v3/src/c++11
% nm thread.o | grep nanosleep

U _nanosleep
