qt4-mac configure segmentation fault when building i386

[develop@…]

Hello, since the 4.7 upgrade and even with the cyclic dependency resolved I cannot build qt4-mac. I of course did a port clean.

Now i obtain :

:info:configure Reading /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_qt4-mac/work/qt-everywhere-opensource-src-4.7.0/translations/translations.pro
:info:configure ./configure: line 8131: 67449 Segmentation fault      QTDIR="$outpath" "$outpath/bin/qmake" -spec "$XQMAKESPEC" "${relpath}/projects.pro" -o "$mkfile"

In the source code, in the configure file, line 8131 is the end of :

if [ "$PLATFORM_MAC" = "yes" ] && [ "$CFG_FRAMEWORK" = "yes" ] && [ "$CFG_DEBUG" = "yes" ] && [ "$CFG_DEBUG_RELEASE" = "no" ]; then
    echo
    echo "Error: debug-only framework builds are not supported. Configure with -no-framework"
    echo "if you want a pure debug build."
    echo
    exit 1
fi

After, a lot of :

:info:configure Creating makefiles. Please wait...
[...]
:info:configure ./configure: line 8273: 68978 Segmentation fault      QTDIR="$outpath" "$QMAKE" $QMAKE_ARGS -o "$OUTDIR" "$a"

configure line 8273 is :

PART_ROOTS=

after, the build :

:debug:build Environment: CPATH='/opt/local/include/dbus-1.0:/opt/local/lib/dbus-1.0/include:/opt/local/include' CC_PRINT_OPTIONS_FILE='/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.m$

:info:build make: *** [Makefile] Segmentation fault

Why, oh why??? Thanks for your clues Thomas

Did you update your system's Java and Xcode already? Have you also installed the Java Update 3 Developer Package (comment:ticket:26934:21)?

I get the same errors here on an Intel Core Duo, Mac OS X 10.6.4, Xcode 3.2.4. It works on an Intel Core Duo with Mac OS X 10.5.8.

The crash log of qmake says:

Here I have an Intel Core Duo, Mac OS X 10.6.4, Xcode 3.2.4 plus updates and the additional install mentioned above. And it works.

[ryandesign (Ryan Carsten Schmidt)]

In the attached log, I see you're building for -arch i386 on 10.6.4. I also get a segmentation fault at the start of the build phase when building for i386 on 10.6.4, though it builds fine for x86_64 on the same machine.

[michaelld (Michael Dickens)]

Looks like the code I added in to handle that scenario isn't working: if not building for the native arch, disable qmake optimization. If you want a "quick" work around, remove the "-optimized-qmake" from the "configure.args".

What do "uname -m" return for those of you having issues?

Replying to michaelld@…:

In my case, your code does what you say. The problem is that qmake optimization fails although it is building for the native arch.

If you want a "quick" work around, remove the "-optimized-qmake" from the "configure.args".

Yes, removing -optimized-qmake from configure.args fixes the problem.

What do "uname -m" return for those of you having issues?

$ uname -m
i386

So, I propose to remove qmake optimization (at least for Mac OS X 10.6 and i386 as build architecture).

[develop@…]

I confirm that when removing the -optimized-qmake in the Portfile I can build qt4-mac. I use an i386 too (Core Duo) with OSX 10.6, XCode 3.2.4, the java updated and the Java Update 3 Developer Package installed. Thanks.

[michaelld (Michael Dickens)]

Thanks all; I agree with raphael & will augment the Portfile to look for 10.6 i386 & remove the optimization for just that version.

[michaelld (Michael Dickens)]

"svn diff" in 'qt4-mac' Portfile, to remove qmake optimization for 10.6 i386 only

[michaelld (Michael Dickens)]

I just added a patch for the current qt4-mac Portfile that might do the trick; I think the syntax is correct, and "port lint" is OK with it too :) Can someone try it out & see if it works for you?

Yes, it works for me.
