DM365 IPNC avi_save compile error

Hi, all

I am try to modify the INFO LIST of the avi file, so I modified the ffmpeg code in /armffmpeg/libavformat/avformat.h

from

#define LIBAVFORMAT_IDENT       "Lavf" AV_STRINGIFY(LIBAVFORMAT_VERSION)

to

#define LIBAVFORMAT_IDENT       "TEST_AVI_MAKER"

And I build a new libavformat.a

The steps I did are :

1. /armffmpeg/configure

2. cd libavformat, make

the a new libavformat.a was build.

But while I copy the library to the folder avi_save/lib/ th replace the original library, and do make all at the folder avi_save

the following error occurs,

/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/../lib/gcc/armv5tl-montavista-linux-gnueabi/4.2.0/../../../../armv5tl-montavista-linux-gnueabi/bin/ld: skipping incompatible ./lib/libavformat.a when searching for -lavformat
/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/../lib/gcc/armv5tl-montavista-linux-gnueabi/4.2.0/../../../../armv5tl-montavista-linux-gnueabi/bin/ld: cannot find -lavformat
collect2: ld exit 1
make: *** [Appro_avi_save] Error 1

And I found that the library I make has a big difference from the original one.

Can anyone help me to solve it.
