undefined reference to `llrint' problem

[fucai1116]

Hi,

I cross compile ffmpeg-export-2007-05-23 with no problem. However when I try cross compile VLC-0.8.6b with static link to ffmpeg, the following error is occured.

/home/hptai/source/vlc/ffmpeg-export-2007-05-23/libavcodec/libavcodec.a(mpegaudiodec.o): In function `decode_init':
/home/hptai/source/vlc/ffmpeg-export-2007-05-23/libavcodec/mpegaudiodec.c:375: undefined reference to `llrint'
/home/hptai/source/vlc/ffmpeg-export-2007-05-23/libavcodec/mpegaudiodec.c:377: undefined reference to `llrint'

The configuration I tried:
CC=arm-linux-gcc
CXX=arm-linux-g++ \

CPPFLAGS=-I/home/hptai/source/buildroot/build_arm/staging_dir/include \

and arm-linux-gcc vesrion is 4.1.1
Can someone help to find out the reason of this problem?

Thank in advance
Tai

Yes, use a former version of ffmpeg with 0.8.6b

[Rémi Denis-Courmont]

It might be a missing function from uclibc if using that.
Also, you may try to build while adding -std=gnu99 to CFLAGS.
