Let me be sure I've understood.
ac++ does source-to-source-translation, and the generated sources are
platform-independent.
For building it for the first time, I'll have to install on my box
(i386) a binary distributed by upstream for i386 (the only architecture
for which they provide binaries), and build it normally.
Then, for architectures other than i386, porters will do the same what I
did (assuming that I'll document it in the debian/rules file), using
some i386 box they have access to generate the C++ source, copy these
sources to a target-architecture box, and build it themselves.
Is that it?
What I thought is that if the translated sources (which are platform
independent) went in the diff, there will be no necessary "by hand"
actions for building in any architecture. But as Joeren wrote, one it is
not recommended to do that. Am I correct?
