[FFmpeg-user] Linking applications with FFmpeg

[Nicolas George]

Le jour de la Récompense, an CCXX, Misha Penkov a écrit :
> mpenkov at misha-desktop:~/git/ffmpeg-tutorial$ make bin/tutorial01.out
> gcc -Wall -ggdb `pkg-config --cflags libavcodec libavformat libavutil
> libswscale sdl` -c tutorial01.c -o obj/tutorial01.o

$(...) is recommended over `...`, but that is unrelated.

> gcc -Wall -ggdb `pkg-config --cflags libavcodec libavformat libavutil
> libswscale sdl` `pkg-config --cflags libavcodec libavformat libavutil
> libswscale sdl` `pkg-config --libs libavcodec libavformat libavutil
> libswscale sdl` -lm obj/tutorial01.o  -o bin/tutorial01.out

Libraries should be added after object files, in dependency order. For
shared libraries that does not matter much but for static libraries this is
mandatory.

Also, this command line seems too complex: you are requesting the cflags
twice, for no reason since you are only linking.

Regards,
