ffmpeg and acer laptop problem


Hi everybody. I've just installed slackware 11 on my laptop. While trying to compile some programs, I realised that a lot of libraries were missing. One of them was ffmpeg/libavcodec. I tried to compile programs like gxine, transcode,vlc etc and they all displayed the same message after configure: couldn't link to libavcodec. I've compiled ffmpeg myself, i've then uninstalled and installed a package from linuxpackages, i've also tried other packages but the configue message is the same. Why?

Also, i have an acer travelmate 433LC. On kde, there is no battery icon and when trying to initiate it it reads something about an acpi problem and recompiling the kernel. Anyone knows what to do and where to find appropriate drivers?

Thanks.

1) you need to post the exact output / error log from configure

2) what kernel are you using ?

I compiled ffmpeg, transcode, MPlayer without problems. I suppose you forgot some options?

I think it's better to download them all from www.slacky.it I tested them and they are working smoothly.

If I remember correctly, those are the options for ffmpeg
./configure --prefix=/usr --enable-a52 --enable-faac --enable-mp3lame --enable-libogg --enable-vorbis --enable-xvid --enable-x264 --enable-faad --enable-gpl --enable-dc1394 --enable-x11grab --enable-faad --enable-libgsm --enable-shared --enable-pp --enable-pthreads

and transcode
./configure --prefix=/usr --sysconfdir=/etc -localstatedir=/var --enable-ogg --enable-vorbis --enable-libdvdread --enable-libdv --enable-libquicktime --enable-a52 --enable-sdl --enable-imagemagick --enable-mjpegtools --enable-libjpeg --enable-lzo

As you can see, you need many libraries like: a52, faac, mp3lame, libdvdcss e.t.c. All available at slacky.it

ffmpeg

ludist, Ihave compiled all of the libraries you mentioned (I mostly compile rather than install a ready package). As for transode,most of the options you mention are already predefined.


H_TeXMeX_H , i use kernel 2.6.17.13. The exact output of the error (from transcode for example) is : error:requirement failed: cannot link against libavcodec. libavcodec can be found in the follwing packages: FFMpeg http://www.ffmpeg.org


and that's about it....

Did you build ffmpeg with --enable-shared (as ludist suggested). If you don't, ffmpeg doesn't build shared libraries by default, so libavcodec won't exist.

Ohhh, I don't know if I am right. BUT:

I experienced the exact error message (AND for liblzo), although I have installed ffmpeg with --enable-shared. So, I was pissed off and proceed with make and I am still using my transcode / ffmpeg package without problems! Funny, strange? I don't know, it works.

Just make sure you have the files like /usr/lib/libavcodec.so e.t.c.

(I am new to this)
