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>/usr/nec/shared-build/bin/moc -DQT_SHARED

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>shout.<br><br>Cheers,<br><br>Ray.<br>_______________________________________________<br>Necessitas-devel mailing list<br><a ymailto="mailto:Necessitas-devel@kde.org" href="mailto:Necessitas-devel@kde.org">Necessitas-devel@kde.org</a><br><a href="https://mail.kde.org/mailman/listinfo/necessitas-devel" target="_blank">https://mail.kde.org/mailman/listinfo/necessitas-devel</a><br><br><br> </div> </div> </blockquote></div> </div></body></html>
