Hey,

I've been trying for about a week now to properly compile vlc using the ffmpeg svn. The reason I need to do so is that I need a few things enabled (lame, swscale). However the problem I always get is that it gives me an error telling me to recompile with -fPIC

Hence I have tried to with many different methods, here is the most obvious one i suppose for configuring ffmpeg:

./configure --enable-gpl --enable-pthreads --enable-postproc --enable-libmp3lame --enable-libx264 --enable-libfaac --extra-cflags=-fPIC

And here is a typical configuration for vlc I've tried (bear in mind ive tried many many different configs ie. adding -fPIC to vlcs cflags to get this to work but all were unsuccessfull).

./configure --prefix=/usr/local --with-ffmpeg-tree=./extras/ffmpeg --with-ffmpeg-faac --with-ffmpeg-mp3lame --enable-x11 --enable-xvideo --disable-gtk --enable-sdl --enable-mad --enable-libdvbpsi --enable-a52 --enable-libmpeg2 --enable-dvdnav --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-faac --enable-mkv --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-caca --enable-skins --enable-skins2 --enable-alsa --disable-kde --enable-qt --enable-ncurses --enable-release --enable-x264 --enable-dvb --enable-libdvbpsi

But even with this I still get an error looking like this:

/usr/bin/ld: /home/chimp/vlc/extras/ffmpeg/libavcodec/libavcodec.a(dsputil_mmx.o): relocation R_X86_64_PC32 against `ff_pw_20' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value

Adding the fPIC to the vlc compile also gives similar errors. I have searched the net and found multiple people with similar problems, but have not as of yet found a solution, any help would be greatly appreciated.

Compiling computer is intel core 2 quad, 8 gig of ram, ubuntu 8.04 server edition.

Almost a year later... I have exactly the same issue, and it is compiled with -fPIC

Did anyone ever find out the problem?

Posted: **08 Mar 2009 05:23**

Had a similar problem. Adding --host-cflags="-fPIC" to the ./configure line fixed it. Hope it helps

1st edit: Oh yeah, I'm running quad core 64-bit red hat with 8G of ram. I think --host-cflags="-fPIC" is necessary for 64-bit x86.

2nd edit: My bad, on ffmpeg it's --host-cflags="-fPIC" and vlc it's --with-pic.
I'm still wrestling with PIC (position-independent code) issues on this system. I think because some of the ffmpeg codecs were built without it and vlc/ffmpeg were. I just read this technical article saying -fPIC is bad because it adds overhead ( http://www.bailopan.net/blog/?p=50#comments )

What's wrong?

You are missing a few linking things like -lz for avcodec... Add those in vlc-config file.

Can't understand what strings must add to the vlc-config file.?

I try this (add "-lz" to libs):

Code: Select all

    ;;
    avcodec)
      cflags="${cflags} -I/usr/local/include"
      libs="${libs} -L/usr/local/lib -lavcodec -lavutil -lm -lz"
    ;;

make
make install

Still the same errors.

Maybe missyng some librarys?

Code: Select all

vlc-coder:~/vlc-0.9.8a_new3# ls /usr/lib | grep avcodec

Well, I reinstalling all system and recompiling vlc. It's work fine!

But mux=ts is not working.

Will be think more..

libdvbpci was missing.
All work fine, thanks =)

Hi, I'm trying to run the ./configure executable for vlc, but I'm not certain how to run this.

I've basically created a new Gentoo server w/ newest portage and such. Did "emerge vlc", and didn't receive any errors while doing this, but VLC just won't work!

Anyway, so my question is how can I run configure in Gentoo, since I installed vlc using emerge.

Please help!

Note, at the beginning of verbose, I get:
