Re: naclport ffmpeg static link error: cannot find -lavcodec

[Jackie Jin]

I also imported nacl-mount lib through naclport, but similarly "cannot find -lnacl-mounts". My computer is corei7 mac. Don't know if it has anything to do with the computer architect.

Hi All,

I'm new to NACL and trying to exercise on using the external ffmpeg lib provided by naclport.

I made ffmpeg inside the naclport and it's compiled into the NACL toolchain.

But there is linkage problem when I try to link it.

I got "x86_64-nacl/bin/ld: cannot find -lavcodec".

This is the flag inside the Makefile LDFLAGS:= -lavcodec -lavutil -lppapi_cpp -lppapi

This is include inside my program

#include "libavcodec/avcodec.h"

When I tried to call avcodec_init() inside the avcodec lib, I got "undefined reference" error.

Is there something I'm missing or did wrong? thank you!

It seems after running 'make ffmpeg' inside naclport, the shared libs put inside the x86_64 lib, causing the x86_64/ld not finding the library.

Can anyone point out things I'm not doing right? Thanks.
