So if i reduce it to
```
x86_64-linux-gnu-gcc -shared build/temp.linux-x86_64-2.7/ffpyplayer/player.o
/home/tangible/Dev/ffpyplayer/ffmpeg/lib/libswscale.a -o
/home/tangible/Dev/ffpyplayer/ffpyplayer/player.so
```
i get the same error, but if i remove the reference to player.o, it
builds, but player.o was also built with -fPIC.
```
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes
-fno-strict-aliasing -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat
-Werror=format-security -fPIC -I/home/tangible/Dev/ffpyplayer/sdl/include/SDL2
-I/home/tangible/Dev/ffpyplayer/ffmpeg/include -I/usr/include/python2.7 -c
ffpyplayer/player.c -o build/temp.linux-x86_64-2.7/ffpyplayer/player.o -O2
-fno-strict-aliasing -Wno-error=format-security -fPIC
```
and no matter how i simplify this, i still get the same error.
```
x86_64-linux-gnu-gcc -I/home/tangible/Dev/ffpyplayer/ffmpeg/include -I/home/tangible/Dev/ffpyplayer/sdl/include/SDL2 -I/usr/include/python2.7 -c ffpyplayer/player.c -o build/temp.linux-x86_64-2.7/ffpyplayer/player.o -fPIC

any help appreciated.

I tried with master (from git://source.ffmpeg.org/ffmpeg.git), as
well as an older commit (1f7b7) that has been tested with ffpyplayer
in the past, to be sure, since i got the same issue, i went back to
master.
I used make clean between each try, and i just tried again with a
make distclean before to be sure, no dice.
Your command does indeed work for me, i'll try to reduce the CC
command of my makefile until i find what flag or target is causing
issue.

Did you run "make distclean" after each try?
What version of FFmpeg is this?
I was unable to reproduce your issue with the following
command:
$ ./configure && make libswscale/libswscale.a
$ gcc libswscale/libswscale.a -shared -o out.so
