My macports.conf has build arch set to ppc64, and my OS is Mac OS X
10.5.8. At some point during a configure script, things like this start to
get printed out a lot, and eventually the build fails.


{{{

It looks like the ppc64 flag is disliked for some reason.

It looks like the '-arch ppc64' flag is disliked and inconsistently
applied.

Comment (by kencu):

As I recall, qt4 uses some assembly language in it's source files to speed
things up. I ran into something like this a year or so ago when I was
trying to build it with a specially-made version of clang-3.8 on PPC.

I'd be surprised if you can get it to build ppc64, but I'd be very pleased
if it worked in the end!

Comment (by michaelld):

According to the qt4-mac configure script, "ppc64" is allowed as an arch
option, if specified correctly. which we might not be doing since I doubt
we've ever had an actual PPC64 available for testing.

I decided to try applying only that patch and then run the build process
again, and it finished. I haven't had a chance to test it yet though.

there are a LOT of patches to qt4 to make it work!!

see this one for the issue you noticed, I think:

Comment (by SerpentChris):

I downloaded the source and looked at the configure file, which lead to me
believe that setting {{{-arch ppc64}}} is actually unnecessary, and what
really needs to be set is {{{-platform macx-g++-64}}}. I also edited my
.profile to export some environmental variables:
{{{
export CC=gcc-4.2
export CFLAGS="-m64 -mtune=G5"
export CPPFLAGS="-I/opt/local/include"
export LDFLAGS="-L/opt/local/lib"
export CXX=g++-4.2
export CXXFLAGS=$CFLAGS
export TMPDIR="$HOME/tempdir"
}}}

This is the configure line I used, it's basically copied from the output
of port -v install, but I removed --jobs=4, -arch "ppc64", and added
-host-big-endian -big-endian -platform mac-g++-64:
{{{
./configure -v -confirm-license -opensource -prefix /opt/local/libexec/qt4
-bindir /opt/local/libexec/qt4/bin -libdir /opt/local/libexec/qt4/lib

declarative-debug -host-big-endian -big-endian -sdk
/Developer/SDKs/MacOSX10.5.sdk -platform macx-g++-64
}}}

This compiles {{{qmake}}} with {{{-arch ppc}}} still for some reason, but
the configure succeeds and the build goes along and builds everything else
with {{{-arch ppc64}}} until it gets to the file
{{{src/gui/dialogs/qfiledialog_mac.mm}}}. When it tries to compile that
file, it seems the file is using a part of the Cocoa framework that isn't
present in OS X 10.5, specifically the build ends with this message:

Googling the undeclared things leads to apple developer pages which state
they are available in macOS 10.6+. Now I'm not sure what to do. How does
it compile without the 64bit platform option? Does it use different code
there for some reason?
