I'm not sure how cross compilation can be the reason, and I'm not sure
whether you're saying you've fixed the issue now; but if you haven't,
then showing the Makefile.am parts relevant for the C++ program as well
as (relevant parts of) a build log would probably help to analyze the
issue.

Automake uses LINK only for linking of C-only code; when it realizes
that C++ is in the game, it will use CXXLINK.  You may need to add
AC_PROG_CXX to configure.ac and run autoreconf for it to set and use
this variable.

(Without knowing what the issue is, it could be due to any of the
autotools; there's really no need to jump to another mailing list
for that, though, IMVHO.)

Hope that helps.

Cheers,
Ralf
