[Boost-users] Static linking program_options on ARM

Hello, I am having trouble when linking Boost::Program_Options statically on Linux ARM 32-bit: it spits an error about a duplicate symbol for a guard-variable. It works fine on Linux ARM 32-bit (same compiler) if using shared libraries, and also on Linux x86-64 both with static and shared libraries. I can reproduce the problem with the examples included in the libs/program_options/examples: real.cpp and custom_syntax.cpp compile and run fine but first.cpp, multiple_sources.cpp options_description.cpp, option_groups.cpp and regex.cpp fail: $ armv7a-openelec-linux-gnueabi-g++ -std=c++11 -o option_groups option_groups.cpp -L $SYSROOT/usr/lib -lboost_program_options /tmp/cch3i9Yf.ltrans0.ltrans.o:(.bss._ZGVZN5boost15program_options10validators17get_single_stringIcEERKSbIT_St11char_traitsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty[_ZGVZN5boost15program_options10validators17get_single_stringIcEERKSbI T_St11char_traitsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty]+0x0): multiple definition of `guard variable for std::basic_string const& boost::program_options::validators::get_single_ string<char>(std::vector, std::allocator > > const&, bool)::empty' /tmp/ccORpK3T.o:(.bss._ZGVZN5boost15program_options10validators17get_single_stringIcEERKSbIT_St11char_traitsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty[_ZGVZN5boost15program_options10validators17get_single_stringIcEERKSbIT_St11char_trai tsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty]+0x0): first defined here /tmp/cch3i9Yf.ltrans0.ltrans.o:(.bss._ZZN5boost15program_options10validators17get_single_stringIcEERKSbIT_St11char_traitsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty[_ZZN5boost15program_options10validators17get_single_stringIcEERKSbIT_St 11char_traitsIS3_ESaIS3_EERKSt6vectorIS7_SaIS7_EEbE5empty]+0x0): multiple definition of `std::basic_string const& boost::program_options::validators::get_single_string<char>(std::vecto r

Compiling Boost with or without C++11 does not affect either (it happens on both cases). Has anyone faced something like this? Thank you -- Pau Garcia i Quiles http://www.elpauer.org (Due to my workload, I may need 10 days to answer)
