Compilation error using gcc 4.1.2 (free not in std namespace)

[anonymous]

Error /home/davidsj2/include/boost/units/detail/utility.hpp: In function 'std::string boost::units::detail::demangle(const char*)': /home/davidsj2/include/boost/units/detail/utility.hpp:48: error: 'mm_free' is not a member of 'std'

On that line, you'll find:

std::free(realname);

In order to get the software to build, I had to change to:

free(realname);

BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION but as a *string* in the form "x_y[_z]" where x is the major version number, y is the minor version number, and z is the patch level if not 0. This is used by <config/auto_link.hpp> to select which library version to link to.

#define BOOST_LIB_VERSION "1_51"

#endif

Same issue w/ gcc 4.4.x and 4.6.x

[Jürgen Hunold]

This is fixed with #10116. We now use Boost.Core implementation of demangle.
