Description Daniel Osmari 2013-08-02 06:25:36 CEST

The gcc-c++-4.7.2-7.mga3 package is incorrectly built.

An important C++11 feature is not enabled due to the compiler being built without the --enable-libstdcxx-time option.

More details here:

http://stackoverflow.com/questions/12523122/what-is-glibcxx-use-nanosleep-all-about



Steps to reproduce:


Type this in a shell:

g++ -x c++ -std=c++11 - << EOF
#include <thread>
#include <chrono>

int main()
{
    std::this_thread::yield();
    std::this_thread::sleep_for(std::chrono::milliseconds(10));
    std::this_thread::sleep_until(std::chrono::steady_clock::now());
}
EOF


The result will be:

<stdin>: In function âint main()â:
<stdin>:6:5: error: âyieldâ is not a member of âstd::this_threadâ
<stdin>:7:5: error: âsleep_forâ is not a member of âstd::this_threadâ
<stdin>:8:5: error: âsleep_untilâ is not a member of âstd::this_threadâ



Current workaround is to tediously add "-D_GLIBCXX_USE_NANOSLEEP -D_GLIBCXX_USE_SCHED_YIELD" to the command line, or edit 
"/usr/include/c++/4.7.2/x86_64-mageia-linux-gnu/bits/c++config.h" to define these macros by hand permanently.


Proper workaround is to rebuild GCC passing "--enable-libstdcxx-time" to the configure script.

Comment 1 Thomas Backlund 2013-08-06 22:45:58 CEST

Indeed, seems no-one was needing / using any C++11 thread stuff...

I will fix it in an update for mga3.

for cauldron / mga4 it will be "automatically" fixed when I switch over to gcc-4.8.2 in ~1 week

Status: NEW => ASSIGNED

Comment 2 Thomas Backlund 2013-09-24 23:29:55 CEST

gcc-4.7.2-8.mga3 submitted to testing

Comment 3 Thomas Backlund 2013-11-18 23:16:36 CET

Advisory:
gcc in mga3 release does not support the C++ nanosleep(),
as it was not properly configured at gcc build time.

This update resolves this by properly enabling nanosleep() support.
It also fixes a reverse sort speed regression since gcc-4.4 
(PR libstdc++/58437)
