Description
This bug affects Qt 4.5.4 binary packages (which include ppc64 binaries), but not 4.6 binary packages (where ppc and ppc64 are not included).
When building the current 4.5 branch on Snow Loepard, with the following configure line
./configure -qt-libpng -qt-libjpeg -plugin-sql-sqlite -plugin-sql-odbc -plugin-sql-psql -framework -confirm-license -no-rpath -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -cocoa -arch x86 -arch x86_64 -arch ppc -arch ppc64 -sdk /Developer/SDKs/MacOSX10.5.sdk
... configure reports the following error:
ODBC support cannot be enabled due to functionality tests! Turn on verbose messaging (-v) to ./configure to see the final report. If you believe this message is in error you may use the continue switch (-continue) to ./configure to continue. Configure error
Calling configure with -verbose does not display any additional information.
I noticed that the part of configure the error comes from has changed in the 4.6 branch, so I tried to backport the changes to 4.5 (8aef5118, e32bc79d, 7278c142).
Those changes add an iodbc configure test, but that test fails on Mac OS 10.6 because the system libraries in /usr/lib no longer have symbols for the ppc64 architecture (they are present in 10.5, where this build succeeds, but not in 10.6), as follows:
Should this configure test link against the libs in the Mac SDK used for the build, rather than the system libraries on the build machine?

If you believe this message is in error you may use the continue switch (-continue) to ./configure to continue. Configure error
If you remove odbc from the configure line, you get a similar failure for psql.
Removing "-arch ppc64" results in a successful build, as does removing "-plugin-sql-odbc -plugin-sql-psql", suggesting that the only problems are the odbc, iodbc and psql configure tests.
