mingw linker errors: undefined references

[Jim Bell <jim@…>]

The MinGW build fails to link, with fifteen or undefined references as such:

bin.v2\libs\serialization\build\gcc-mingw-4.4.0\release\threading-multi\basic_iarchive.o:basic_iarchive.cpp:(.text+0x564): undefined reference to `_imp_ZNK5boost13serialization18extended_type_infoltERKS1_'

Cause: the BOOST_SERIALIZATION_SOURCE flag isn't being set. Note that this flag is distinct from BOOST_ARCHIVE_SOURCE.

The attached patch file modifies the Jamfile.v2 to pass that flag into every compilation unit. Maybe that's the final solution, but it resolves this issue.

Jim, could you post the full error your getting? I'd like to see that before applying your patch.

[Jim Bell <jim@…>]

Please forgive the typos: "... fifteen or so undefined references ..."

And that example without WikiFormatting is:

bin.v2\libs\serialization\build\gcc-mingw-4.4.0\release\threading-multi\basic_iarchive.o:
basic_iarchive.cpp:(.text+0x564):
 undefined reference to `_imp___ZNK5boost13serialization18extended_type_infoltERKS1_'

Which, demangled (without the win32 'imp' prefix) is:

boost::serialization::extended_type_info::operator<(boost::serialization::extended_type_info const&) const

I'll attach the full list of linker undefined references, but wanted put these here (for the search engines to find).

Boo, this means serialziation is just totally unusable on mingw, and there's easy fix? Let consider for 1.45

Thanks for the patch, Jim. As of r66123 this is fixed. Hopefully it doesn't break anything on other compilers.

[Robert Ramey]

I've updated the library so that this isn't needed please don't check this in.

Ramey - I asked on Boost.Users for people to confirm, I got reports back that this was not fixed. I was unable to build without this patch. I've already committed it, ofc we can always revert if need be.

[Bryce Adelstein Lelbach]

Sorry Ramey - I thought this was Jim's other patch. You are correct, this isn't needed and I have NOT applied this patch. In my comment I was thanking Jim for the report/submission.
