Me too faced same issue, while using code-sourcery tool chain. see http://groups.google.com/group/android-porting/browse_thread/thread/b9196c6398d548f1/d5c2f2894db1b859
android uses native libc (bionic) and not regular gnu libc.. Bionic is a slim libc, optimized for embedded space.. it has own advantage like smaller size (aids faster lib loading for each process), licensing (not GPL, but BSD), and faster.. So, if you build a module with GNU lilbc, most likely it will fail to run in android, due to missing libraries.. -Deva On Thu, Mar 25, 2010 at 1:52 AM, pavan savoy <[email protected]> wrote: > Why build using Code-Sourcery, build with the toolchain what android uses. > I suppose the problem exists there. > > Everything is EABI, everything is supposed to work as is, But as far as I > have seen, it never does. > give it a shot with > mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- > > regards, > Pavan > > On Wed, Mar 24, 2010 at 11:27 AM, priya <[email protected]> wrote: >> >> Hi all, >> >> [1] >> >> I have built a c++ shared library (.so) using code sourcery >> toolchain.
