[Ffmpeg-devel] Compiling FFMPEG under local diretory with mp3lame enabled

[Suan_ZHU]

Hello all,

I have two accounts for running a video processing site. One is a managed
server, which means that I have no root user privileges and can not install
any software or files into the usr/bin/ directory. Which means that make
install command for any packages will not work.

for example, I compiled lame version 3.97 locally and tries to make install
it onto the root, the following commands printed out:

 make install

after I compiled mp3lame library locally under my machine, I put ffmpeg
under lame library,
and I first compiled ffmpeg, I get the following error:

>lame/lame.h: file does not found

after I modied the file and changed the line <lame/lame.h> to
"../lib/lame.h"


I compiled again, and I get the following error:

make: *** [ffmpeg_g] Error 1


it seems that FFMPEG tries to find the file libmp3lame.so under usr/bin/
of course, I am not allow to copy file into that directory, I do find such
file under my local
lame-3.97/libmp3lame/.libs/  directory


my question is that is it possible that I could compile FFMPEG locally with
mp3lame enabled?
I may need to modify the make file or configuration so that FFMPEG will
recognize the location of libmp3lame.so under
./libmp3lame/.libs/libmp3lame.so ?????


I am not too sure what I should do in this case?
should I go to libavformat and modify the makefile and, in general, is it
possible to compile FFMPEG with LAME located only at the local directory.

please help!!

thanks and appreciated.
