Re: [Mingw-cross-env-list] Question on cross-compiling boost context library

[Nagaev Boris]

Hey,

MXE provides GNU assembler (usr/bin/<target>-as). I suspect that it is
not what boost.context needs though...

Current version of boost in MXE is 1.60 and it builds on all my 64 bit
Linux machines (Debian) without errors. I do not use boost.context so
I don't know if it actually works. There is an open bug about support
of exceptions inside coroutines of boost.context [1].

I have tried to update boost to 1.62 and it failed with linking errors
because of boost.context [2]. There is a pull request [3] for
boost.context that is reported to fix it for release but not for
debug. It doesn't work for me (see my comments there) and it doesn't
look like a correct solution. According to one of comments, things are
the same in 1.63.

So I think that support of boost.context in MXE is broken if any.
Maybe we should disable it explicitly not to confuse people?
