[odb-users] ODB on Android

[Wolfgang Haupt]

Hi,

I'm trying to get odb working for android.
So far I read: http://wiki.codesynthesis.com/Using_ODB_on_Android

And I can cross-compile libodb and libodb-sqlite+libodb-mysql just fine.

However I struggle to see how this will work together with the odb compiler.
In the above guide there is no word about the odb compiler itself, so I 
tried
to use the binary distribution for linux.
When I do this I have to patch: 
/arm-linux-androideabi-21-debug/lib/odb/x86_64-linux-gnu/include/c++/4.9.3/x86_64-linux-gnu/bits/os_defines.h/

Because /__GLIBC_PREREQ/ is not defined.
Then I get more errors:

/In file included from 
/home/a1rwulf/Android/android-ndk-r18b/sysroot/usr/include/features.h:33:0,//
//                 from

error: attributes are not allowed on a function-definition//
//         __prefer_this_overload {/

I'm pretty sure it is because the compiled gcc included in the binary 
distribution package does of course target
Linux and not Android and there will be a mismatch in the libc or 
libstdc++ etc. (I lack knowledge in this area)

I then tried to compile odb for Android, but I don't really see how this 
works as Android has switched to clang
and the toolchain does not have a gcc with plugin support.

Any ideas on how to proceed with this?
Did anybody already get this working with recent Android NDK's (I'm 
using NDK 18b atm)?
