How does mythtv know what architectures the user has requested in
the macports.conf file? That's the information those last 7
variables contain.
You're right, it doesn't. The port also doesn't support universal
building. I freely admit that I know very little about c/c++/objc
compiling and linking although I've learned quite a bit in the last
1.5 years working on this port.
What I had noticed was that quite a few compile/link flags were being
duplicated somewhere in the build toolchain:
MacPorts/configure/qmake/XCode/whatever.
In light of that and last fall's build problems
(https://trac.macports.org/ticket/35934), the approach of clearing
all these flags--ala the qt4-mac port--looked interesting. BINGO.
Much cleaner builds on XCode 3.2.6, working build with clang from
XCode 4.6.mumble, plus a working build on a 32-bit Core Duo machine
for the first time. IOW, huge improvement.
Nonetheless, I take your point. I will look for a way to pass the
desired arch to Myth's configure. For mythtv-core.27 (0.26 is
unworkable on OS X), I'll can have a look at a universal build.
