qt4-mac @4.5.2 +universal fails on 10.6 due to -arch -arch

[eric.nodwell@…]

qt-mac @4.5.2 +universal fails on 10.6 (Snow Leopard). This is due to a double '-arch -arch' appearing in a build command. See the attached debug log qt4-mac_universal.log , generated from 'sudo port -d install qt4-mac +universal buildmakejobs=1'. (All the dependencies were also build with +universal).

The pertinent lines from the log are:

/usr/bin/g++-4.2 -arch x86_64 -arch i386 -Xarch_i386 -mmacosx-version-min=10.4 -Xarch_x86_64 -mmacosx-version-min=10.5 -arch -arch -Xarch_x86_64 -mmacosx-version-min=10.5 -o ../../../bin/moc release-shared/moc.o release-shared/preprocessor.o release-shared/generator.o release-shared/parser.o release-shared/token.o release-shared/main.o    -L/opt/macports/lib -L../bootstrap -lbootstrap -L/opt/macports/lib -lz -framework CoreServices
g++-4.2: Invalid arch name : -arch
make[1]: *** [../../../bin/moc] Error 1

This error is very similar to an error that afflicted gcc and was reported in #20280. In that case it was fixed in changeset r54512. I have however been unable to successfully copy that fix to qt4-mac/Portfile.

Note that this is different than the error that in generated for a non-universal build, which is reported in #20435.

Same here, but i think i solved the problem.. my output was

Command output: cd src/tools/bootstrap/ && /usr/bin/make -f Makefile 
make[1]: Nothing to be done for `first'.

g++-4.2: Invalid arch name : -arch

what i did then was

cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_qt4-mac/work/qt-mac-opensource-src-4.5.2
sudo open src/tools/bootstrap/Makefile
sudo open src/tools/moc/Makefile
sudo open src/tools/rcc/Makefile
sudo open src/tools/uic/Makefile

and looked for the "-arch -arch" arguments, wich turned out to be in the makefile.. deleting them seems to work for me.. still compiling right now.

[jochen.mueck@…]

there are some more "-arch -arch" statements in src/corelib/Makefile.Debug and Makefile.Release

[jochen.mueck@…]

now i searched for -arch -arch in the qt folder.. found about 380 Makefiles.. this could be done with a skript or something

Proposed Patch for the "-arch -arch" problem

[royliu@…]

This error is caused by the QT build system doing smart things under the hood and conflicting with the CPPFLAGS set by configure.universal_cflags. The solution is to null out all universal flags and go through the configure script's "-arch" switch. Please find patch attached.

[macsforever2000@…]

Your patch works. I applied it in r57219. Thanks!
