<div>Q.'''- I am trying to compile VLC and i'm getting the errors "Missing header file ffmpeg/avcodec.h" and/or "Missing header file postproc/postprocess.h" '''<br />
<br />
A. To get rid of these problems while compiling, run configure with these flags at least: ./configure --enable-shared --enable-shared-pp --enable-pp --enable-gpl<br />
<br />
The description of each of those is available when doing ./configure --help<br />
<br />
Q.'''- I am trying to compile VLC and on a 64 bit system and i'm getting the errors "cc1: error: invalid option `tune=opteron'"'''<br />
<br />
A. From what I can see, the -mtune flag is not available for this type of processor in man gcc. I had to change the configure options comment out all the lines where they set mcpu or mtune flags.) I don't know if this is the correct way to proceed but was the only way for me to get results fast.<br />
<br />
Q.'''- I am trying to compile VLC and on a 64 bit system and i'm getting the errors "/usr/bin/ld: cannot find -lX11"'''<br />
<br />
A. In the configure, there is an x_libraries variable there that is set to "/usr/X11R6/lib" (around line 16371). Because it is a 64 bit system, this variable needs to be /usr/X11R6/lib64. After changing that, it should continue compiling.</div>Lucgallanthttps://wiki.videolan.org/index.php?title=Linux_VLC_FAQ&diff=2397Linux VLC FAQ2005-11-03T15:01:07Z<p>Lucgallant: </p>

<br />
A. From what I can see, the -mtune flag is not available for this type of processor in man gcc. Edit the configure where it says mtune=opteron to say march=k8. It will pass that error. (Putting it as march=opteron should work according to the man pages, but I put k8 anyway).</div>Lucgallanthttps://wiki.videolan.org/index.php?title=Linux_VLC_FAQ&diff=2395Linux VLC FAQ2005-11-03T14:19:57Z<p>Lucgallant: Compiling problems</p>
