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 libavcodec as a shared object library by specifying
--enable-shared --disable-static or something to that effect
I get the 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
with -fPIC
when Im trying to use the function av_register_all(), belonging to
libavcodec, in a library that I am programing (libmylibrary.so)
For compiling libavcodec, I am doing ./configure, make, make install in
the directory of ffmpeg-0.11.1, wish contains libavcodec, libavutil,
etc... the result of this is libavcodec.a, libavutil.a, etc...

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' can not be used when making a shared object;
recompile
with -fPIC
///////
I think that I have to set the flag -fPIC for compiling the
libavcodec, libavutil, libavformat, so I added: enable pic , in
the configure file of the ffmpeg project:
# OS specific
case $target_os in
linux)
add_cppflags -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600
enable pic
enable dv1394
Therefore when ffmpeg is compiled, libavcodec, libavutil,
libavformat were compiled with -fPIC.... then when should be ok If
I want to use them in my libx.so ... but It is not, I 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
with -fPIC
I dont know wish is the problem with ffmpeg and -fPIC...

Hi!!! Im developing an aplication using libavcodec,

I have to get
libavs compiled with -fPIC ... I was trying to do it by

If you are trying to combine several ffmpeg libraries into a
single shared
library as I have seen some apps try to do then you need to
use the
following linker flag on the final library build step.
-shared -Wl,-Bsymbolic
