In parseheader_generic.py, there is fpic defined, but I think it might need
the __PIC__
generator_path, generator_name = utils.find_xml_generator()
xml_generator_config = parser.xml_generator_configuration_t(
xml_generator_path=generator_path,
xml_generator=generator_name,
include_paths=self.include_paths,
compiler='gcc',
undefine_symbols=['__PIE__'],
#define_symbols=['BOOST_ATOMIC_DETAIL_EXTRA_BACKEND_GENERIC', '__PIC__'],
define_symbols=['BOOST_ATOMIC_DETAIL_EXTRA_BACKEND_GENERIC'],
cflags='-std=c++11 -fPIC')
