I am building a shared library which will be distributed to clients in binary form only. I am attempting to make the same binary run on as many Linux variants as possible, and so when I build it I specify the
options -shared and -fPIC. As part of the effort of making the library as independent as possible, I also link both the C and C++ standard libraries statically into the final shared library. I want to do this because I use
C++11 features internally, and I don't want to force the users of my library to have a C++11 compiler handy.
When doing this, do I need to build libstdc++ and libgcc from source with -fPIC as well? Or is it okay to link with the static versions of these libraries that are provided in my Ubuntu 13.04 gcc package?
To clarify, no exceptions are thrown over library boundaries; all exceptions used internally in the library are caught and processed behind the scenes. None of them ever reach the client code, as the client communicates with the library using a plain C interface.
My exact build flags are as follows:
g++ -fvisibility=hidden -fvisibility-inlines-hidden -static-libstdc++ -static-libgcc -s -DNDEBUG -std=c++11 -Wall -shared -fPIC -o libtest.so test.cpp -lpthread -O2
