This is what I get: # gnatmake -j1 -fPIC -p -Pdebian/build_aws.gpr -Xkind=dynamic -Xsoname=libaws.so.2.10.2 building dynamic library for project build_aws gcc-4.6 -shared -o /root/libaws-2.10.2/debian/tmp/dynamic//libaws.so.2.10.2 ... /root/libaws-2.10.2/debian/tmp/obj-dynamic/aws-services-directory.o ... /usr//bin/ld: /usr/lib/gcc/arm-linux-gnueabihf/4.6/adalib//libgnarl-4.6.a(s-taprop.o): relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/lib/gcc/arm-linux-gnueabihf/4.6/adalib//libgnarl-4.6.a: could not read symbols: Bad value collect2: ld returned 1 exit status gnatmake: gcc-4.6 execution error It still looks like a problem in libgnarl-4.6.a to me. armhf is built with Thumb2 which according to some more knowledgeable people than myself, has only 25 bits for largest relocation vs 27 bits in arm mode. Usually, this is not a problem but some packages do fail to build because of this. What works without -fPIC on most architectures, can potentially need -fPIC on armhf (and I've filed quite a few bugs about this myself.
