Hi Sandeepa,

We are trying to build android Kitkat (for our own platform) using linaro android toolchain version 4.7.4 from 13.12 release. We are observing following while compiling some shared libraries:

~arm-linux-androideabi-4.7/bin/../libexec/gcc/arm-linux-androideabi/4.7.4/real-ld: warning: shared library text segment is not shareable ~arm-linux-androideabi-4.7/bin/../libexec/gcc/arm-linux-androideabi/4.7.4/real-ld: error: treating warnings as errors

We tried to suppress thisn warning by setting LDFLAGS but the tool-chain does not seem to identify this flag: LOCAL_LDFLAGS := --no-warn-shared-textrel

We need some help to fix this, so posting on both android and tool-chain mailing lists.

It should be possible to run "arm-linux-readelf -r" on the shared library to discover which symbol is being referenced with a non-shareable relocation (i.e. a reloc that modifies the text segment) from there you should be able to track down where that reference occurs ("arm-linux-objdump -d" will help you find the function/compilation unit where the reference is).

Usually the cause is either an assembly coding error or some code being built without -fPIC.
