Bug #: 52900
Summary: Compile source using Boost header with -static -flto
-std=c++11 breaks
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gccb...@haatschii.de
A minimal source creating the error is:
#include "boost/program_options.hpp"
int main ( int argC, char* argV[] )
{
return 0;
}
Where "boost/program_options.hpp" is the Boost header file (Version 104700).
When compiling this source using:
g++-4.7 test.cpp -I ../includes -std=c++0x -static -flto
I get the following errors:

collect2: error: ld returned 1 exit status
However it compiles fine when I omit either -static, -flto or -std=c++0x. Only
if all three options are present the error occurs. I am on Debian Wheezy. I
have tested the error with two g++ versions:
g++ (Debian 4.6.3-1) 4.6.3
g++-4.7 (Debian 4.7.0-1) 4.7.0
Hope this helps and feel free to contact me.
