Hi,

I'm trying to build some shared libraries with the Linaro Android toolchain.
For all of my libraries I get the following errors from the linker:

|BlaBla.cpp.o: requires unsupported dynamic reloc R_ARM_REL32; recompile
with -fPIC

/home/dev/android/android_linaro_toolchain/libexec/gcc/arm-linux-androideabi/4.7.1/real-ld:
error: hidden symbol '__dso_handle' is not defined locally
|

I'm using -fPIC in the compiler's flags so I'm not sure why the linker is
complaining.
The |__dso_handle| error is supposed to have been fixed in the NDKr6. I
tried the
Linaro 4.7.1(2012.05) toolchain, the one available for download, one of the
daily
builds from Linaro of the same toolchain(the one from Friday last week) and
I also
rebuilt entirely the toolchain from source but with the same results. I
found a bug
report in the
launchpad(https://bugs.launchpad.net/igloocommunity/+bug/1000200)
which pretty much describes exactly the same problem but unfortunately none
of the
observations made there helped(I do have -fPIC in the compilation flags, I
do not
have any assembly source and I rebuilt the toolchain from source).

Does anyone have any hints on how to fix or overcome the problem?
Hi Marius.  I've cc'ed this to the linaro-android list.  They might be
able to help.

Hi Michael,

Thanks a lot.
 
Just a couple of more details:
- the source code base builds fine with the Android Linaro
toolchain 4.6 (Linaro GCC 4.6-2012.05) 4.6.4 20120508.
- for the build of the 4.7.1 toolchain I've done on my machine I
applied the Linaro specific gcc patches
