What to do with "recompile with -fPIC" message
22,729
Solution 1
There is a ./configure option which might be the easiest way to solve the issue:
andrew@ilium~/source/ffmpeg_build/ffmpeg/ffmpeg$ ./configure --help | grep -i pic
--enable-pic build position-independent code
Solution 2
I have solved the same error for compiling FFMpeg 2.3.3 sources at Ubuntu 14.04 LTS. I have successfuly compiled the code after set LD_LIBRARY_PATH
to /usr/lib/x86_64-linux-gnu
and added -fPIC
flag to --cc
. My working compile commands is here :
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
./configure --prefix=.. --enable-shared --enable-gpl --enable-version3 --enable-runtime-cpudetect --disable-outdev=sdl --disable-opencl --enable-libmp3lame --enable-libx264 --cc="gcc -m64 -fPIC" --extra-cflags="-I../include" --extra-ldflags="-L../lib -ldl"
make -j4

I'm trying to configure the ffmpeg source package to build .so files rather than .a files.
I run
make
after doing./configure --enable-shared
This gives me the following message:
/usr/bin/ld: libavutil/display.o: relocation R_X86_64_PC32 against undefined symbol 'hypot@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
However, I'm not sure where and how to add the -fPIC flag.

saiarcot895 almost 10 years.so files are the standard in Ubuntu. In which (binary) packages are you unable to find .so files?
