libjsonrpccpp-common.a is not compiled with -fPIC flag

[Kamil Gardziejczyk]

Hi,

I have C++11 application that uses libjsonrpccpp. The application was working fine with previous library packages.

Packages are installed using apt-get:

ii libjsonrpccpp-client0 0.6.0-2build1 amd64 library implementing json-rpc C++ clients
ii libjsonrpccpp-common0 0.6.0-2build1 amd64 common functionality for server and client library
ii libjsonrpccpp-dev 0.6.0-2build1 amd64 development files for JSON-RPC C++ framework
ii libjsonrpccpp-server0 0.6.0-2build1 amd64 library implementing json-rpc C++ servers
ii libjsonrpccpp-stub0 0.6.0-2build1 amd64 library for stub generation of libjsonrpccpp based applications
ii libjsonrpccpp-tools 0.6.0-2build1 amd64 stub generator for libjsonrpccpp based applications

Currently, during compilation (for both, clang and gcc) I`m getting the following error.

clang:
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libjsonrpccpp-common.a(specificationparser.cpp.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC

You are trying to link against the static versions of the library, which are not -fPIC compiled by design.

[Kamil Gardziejczyk (belussi-pl)]

Ok. Got it. In previous version of my app the library was compiled by me in static mode with -fPIC. Now, I`d like to use the one provided by OS. What is the reason to not compile it by default with -fPIC in static version?
