C++0x "Hello Concurrent World" immediately segfaults on g++/linux?
Browsing through a Currency in C++0x book and thought I would give the sample code a run. It is as basic as it gets.
#include <iostream>
#include <thread>
void hello()
{
std::cout<<"Hello Con开发者_StackOverflowcurrent World\n";
}
int main(int argc, char *argv[])
{
std::thread t(hello);
t.join();
}
Compiled with:
g++ -std=c++0x -g -o pgm pgm.cpp
Goes boom with:
Program received signal SIGSEGV, Segmentation fault.
_dl_fixup (l=0x7ffff7b0992c, reloc_arg=<value optimized out>) at ../elf/dl-runtime.c:147
147 ../elf/dl-runtime.c: No such file or directory.
in ../elf/dl-runtime.c
Appears to be a setup/library issue of some kind. Anyone familiar with this?
You need to compile/link using the -pthread
flag.
