<p>Wow, you fixed it at such a low level. Excellent. I just looked into it a little bit and thought that the problem was that moc doesnt handle macro expansion so we were a bit buggered, but wow, your fix looks general enough!</p>
<p>Ill give things a good test over the weekend. When do you hope to get the release ready by?</p>
<p>Btw, I've been working with the mer team on upgrading their compilers to linaro 4.6.2 and carsten munk is testing it, so I think this is great as it will give me some more confidence in their stability if the testing gives good results.</p>

<b><span style="font-weight:bold">Subject:</span></b> Rebuilding Android Qt with Linaro GCC 4.6.2.<br> </font> <br>
Hi guys,<br><br>I sent this email to BogDan, but really, this list is a more<br>appropriate place for it (and Gmail and Yahoo don't like talking to<br>each other sometimes, so I don't think he's getting my emails<br>
delivered promptly).<br><br>Sorry this is a bit long-winded! I managed to track down (on Linux)why<br>Qt Android doesn't build correctly with Linaro GCC 4.6.2 finally (btw<br>I released to the ndk mailing list the newest versions with<br>
important neon fixes)... It's important that I get the 4.6.2 build<br>working and tested as neon will probably never work properly in 4.4.3,<br>plus 4.6.2 brings all sorts of other niceness (Cloog/Graphite + auto<br>parallelism).<br>
<br>On Ubuntu Linux GCC 4.6.1 Host Qt build works, here's a snippet of the commands:<br>pushd /usr/nec/shared-build/src/corelib<br>rm .moc/release-shared/moc_qabstractanimation.cpp<br>make<br><br>...executes...<br><br>

...and fails...<br>usr/nec/android-ndk-r6b/sources/cxx-stl-4.6.2/gnu-libstdc++/include/bits/stl_relops.:68:<br>Parse error at "std"<br>make: *** [.moc/release-shared/moc_qabstractanimation.cpp] Error 1<br><br>...I
examined the moc command lines in detail and the difference is<br>that we explicitly add the gnulibstdc++ includes path(s):<br>"-I/usr/nec/android-ndk-r6b/sources/cxx-stl-4.6.2/gnu-libstdc++/include<br>-I/usr/nec/android-ndk-r6b/sources/cxx-stl-4.6.2/gnu-libstdc++/libs/armeabi/include"<br>
<br>So I tested adding the equivalent (-I/usr/include/c++/4.6.1) to Ubuntu:<br>/usr/nec/shared-build/bin/moc -I/usr/include/c++/4.6.1 ...etc...<br>etc... /usr/nec/qt-src/src/corelib/animation/qabstractanimation.h -o<br>.moc/release-shared/moc_qabstractanimation.cpp<br>
and it fails in much the same way:<br>usr/include/c++/4.6/bits/stringfwd.:43: Parse error at "std"<br><br>Which is good as it identifies that this is the problem. Moc can't<br>handle very recent libstdc++ headers (because it doesn't do macro<br>
expansion).<br><br>For us, the problem obviously because in qmake.conf we've got:<br>ANDROID_SOURCES_CXX_STL_INCDIR
=<br>$$NDK_ROOT/sources/cxx-stl-$$ANDROID_CXXSTL_SUFFIX/gnu-libstdc++/include<br>$$ANDROID_SOURCES_CXX_STL_LIBDIR/include<br>QMAKE_INCDIR = $$ANDROID_PLATFORM_PATH/include<br>$$ANDROID_SOURCES_CXX_STL_INCDIR<br>
<br>So I guess we need to not add this when mocc'ing, but I'm not sure how<br>best to achieve this.<br><br>I guess we could have QMAKE_INCDIR_MOC which doesn't get these things<br>added or something like that? If anyone's got any thoughts then please<br>
