By the way I noticed when I pulled the QtCreator from git the
.gitignore seems to have ignore of lib/* and in lib/qtcomponents
there seem to be a few files that are not created in the build
process.. Perhaps the .gitignore is not correct for<a

Rather than building your own NDK from Google's code (and thus ending
up with the same bugs) you should either use mine (it's the one we
supply and use with Necessitas):

...or else build mine using the script we use:
<a class="moz-txt-link-abbreviated" href="mailto:git@git.kde.org:necessitas-tools.git">git@git.kde.org:necessitas-tools.git</a> (master branch)
look at build_ndk.sh in that repo.
for building android qt, look at build_sdk.sh which calls
android/androidconfigbuild.sh

<pre wrap="">Hi Ray,
Thanks for the warnings!
I am using Googles android-ndk-r8b NDK, with the latest compilers (v4.6)
because I wanted to use the same NDK I used for OpenCV that I also am using
on the same project - in theory it should keep things simple. Thanks for
the answers also about using "android:" to selective configure stuff. I
will look out for the failures that you mention.. I might end up building
the Google compiler and linker at this rate..
Peter.

Hi Peter,
Which NDK are you using? Ours or Google's? Google's won't work for 2
reasons, their libgnustl_static.a has it's symbols invisible and also
their linker has a bug in it to do with a specific relocation type.
Also are you using the unstable branch of the Qt sources?
Only libQtCore4.so gets linked to libgnustl_static.a:
from qt-src\src\corelib\corelib.pro
android: {
#add whole gnu_stl library to QtCore
LIBS_PRIVATE += -Wl,--whole-archive
$$ANDROID_SOURCES_CXX_STL_LIBDIR/libgnustl_static.a
-Wl,--no-whole-archive
}
On android libstdc++ is just a few small support functions for C++.

Hi,
I am building from source and plan to run on an android 4.1.1. I am
using
Ubuntu 64bit machine for the build and am using android-ndk-r8b.
I find errors such as
obj/release/JSBase.o:(.ARM.extab.text.JSReportExtraMemoryCost+0x0):
undefined reference to `__gxx_personality_v0'
that are fixed by adding to the .pro file
QMAKE_LIBS += -lgnustl_shared
because in android the shared library file is named "libgnustl_shared.so"
instead of "libstdc++.so" as on other platforms (see
CPLUSPLUS-SUPPORT.html).
I tried to make this change in mkspecs/android-g++/qmake.conf but had
other
errors. Is there a construct that I can use in the .pro files such as
neon:*-g++* { ... }
that will make this change for just android builds of Qt? Is there a
better
way to fix this linker problem in necessitas?
Thanks
Peter.
