Package: libstdc++-4.8-dev
Version: 4.8.2-15
Severity: important
File: libstdc++
Tags: upstream
Dear Maintainer,
-static-libstdc++ does not seem to be working anymore.
Consider this following test application:
---------------------
#include <iostream>
#include <string>
int main()
{
std::string s;
if (s.empty()) { std::cout << "String is empty!" << std::endl; }
return(0);
}
---------------------
g++ -Wall -o test test.cpp -static-libgcc -static-libstdc++
"test" here should not contain any references to libstdc++ symbols as it is
being linked statically, however, "objdump -T test" contains the following:
00000000006915c0 u DO .bss 0000000000000020 Base
_ZNSbIwSt11char_traitsIwESaIwEE4_Rep20_S_empty_rep_storageE
0000000000691600 u DO .bss 0000000000000020 Base
_ZNSs4_Rep20_S_empty_rep_storageE
These are both symbols from libstdc++ that should have been staticaly linked,
yet they are now undefined, and indeed, this binary will not run on a system
without a sufficiently up to date libstdc++ installed.
The same problem occurs with:
clang++ -Wall -o test test.cpp -static-libgcc -static-libstdc++
So the problem seems to be more of an interaction with libstdc++ and the linker
than the compiler in question.
An older Debian setup I have back when GCC 4.6 was current does not exhibit the
problem here.
