Problem building Boost 1.40 for Mac OS 10.3.9

[anonymous]

When trying to build Boost (regex) using:

./bootstrap.sh -with-libraries=regex ./bjam

I get the following (first of many) error:

cc1plus: warning: `dwarf-2': unknown or unsupported -g option boost/regex/v4/cpp_regex_traits.hpp: In member function `bool

Any ideas?

Thanks,

This is a known issue with older gcc versions, it's fixed by this patch: ​https://svn.boost.org/trac/boost/changeset/55837/trunk/boost/regex/v4

HTH, John.
