[C++-sig] boost.python and MinGW3.4.2 with eclipse

[Raoul Gough]

[I think this is probably off-topic on this list - the c++-sig is for
Python/C++ integration, not boost topics in general]

This link command won't work because the arguments are in the wrong
order. You need to put the objects with unresolved symbols first, so
the linker knows what symbols it's looking for when it processes the
library archive*. No idea why Eclipse would be getting this wrong.

* Actually there's another way to do it by wrapping linker arguments in
( and ) but you only need to do that if there are circular dependencies
between archives, which you never want anyway.

Don't know, but you'd be better off asking on one of the general boost
mailing lists than here.
