Hi,
did you solve the problem?
I experienced it when I was trying to include static ffmpeg libraries
(libavcodec.a, libavformat.a ...) in my shared lib (mylib.so) on a 64 bit linux
platform, but I don't know how to solve, can you help me please?

I'd like to make a shared library called mylib.so that include static ffmpeg

I'm working on a linux machine 64 bit (ubuntu 12.04).
I've built ffmpeg libraries from ffmpeg 2.0.1 sources with this

Hi Gavin!!
I set
-shared -Wl,-Bsymbolic
in the linker flags of my library, that depends of libavcodec, libavutil,
libavformat...
However when Im going to call av_register_all(); I get the same error:
/usr/local/lib/libavcodec.a(lpc_mmx.o): relocation R_X86_64_PC32 against
symbol `ff_pd_1'

I am a little confused, do you get this error when you are trying to use
libavcodec.a into another of your projects or during compilation of
libavcodec itself? In the latter case why are you building a static
library (i.e. libavcodec.a instead of a libavcodec.so ) ? You need to
build

Let me correct myself. The problematic symbol in the situation here is
ff_pd_1, a global variable. It's declared with the attribute
visibility(hidden). The symbol isn't exported. Knowing this, gcc apparently
doesn't generate PIC code for accessing it even when you add -fPIC.
By default, gcc

This is not a good idea since an equivalent
option exists (that may set additional settings).

I tried with ./configure --extra-cflags=-fPIC and I still have the
same error:
/usr/local/lib/libavcodec.a(lpc_mmx.o): relocation R_X86_64_PC32 against
symbol `ff_pd_1' can not be used when making a shared object; recompile
