[vlc] Re: about xvid surpported by vlc

[chenxuekai at zju.edu.cn]

supplement:
the the version of source code we used is 0.7.2
we only let the codes are incapable in configure.ac be active.
the original code is such as
-------------------------------------------------
dnl dnl
dnl dnl  xvid decoder plugin
dnl dnl
dnl AC_ARG_ENABLE(xvid,
dnl [  --enable-xvid           xvid codec (default disabled)])
dnl if test "${enable_xvid}" = "yes"
dnl then
dnl   AC_ARG_WITH(xvid,
dnl     [    --with-xvid=PATH      path to xvid installation],[],[])
dnl   if test "${with_xvid}" != "no" -a -n "${with_xvid}"
dnl   then
dnl     AX_ADD_CPPFLAGS([xvid],[-I${with_xvid}/include])
dnl     AX_ADD_LDFLAGS([xvid],[-L${with_xvid}/lib])
dnl   fi
dnl 
dnl   AC_ARG_WITH(xvid-tree,
dnl   [    --with-xvid-tree=PATH xvid tree for static linking])
dnl   if test -n "${with_xvid_tree}"
dnl   then
dnl     AC_MSG_CHECKING(for libxvidcore.a in ${with_xvid_tree})
dnl     real_xvid_tree="`cd ${with_xvid_tree} 2>/dev/null && pwd`"
dnl     if test -z "${real_xvid_tree}"
dnl     then
dnl       dnl  The given directory can't be found
dnl       AC_MSG_RESULT(no)
dnl       AC_MSG_ERROR([cannot cd to ${with_xvid_tree}])
dnl     fi
dnl     if test -f "${real_xvid_tree}/build/generic/libxvidcore.a"
dnl     then
dnl       dnl  Use a custom xvid
dnl       AC_MSG_RESULT(${real_xvid_tree}/build/generic/libxvidcore.a)
dnl       AX_ADD_BUILTINS([xvid])
dnl       AX_ADD_LDFLAGS([xvid],[-L${real_xvid_tree}/build/generic -lxvidcore])
dnl       AX_ADD_CPPFLAGS([xvid],[-I${real_xvid_tree}/src])
dnl     else
dnl       dnl  The given libxvidcore wasn't built
dnl       AC_MSG_RESULT(no)
dnl       AC_MSG_ERROR([cannot find ${real_xvid_tree}/build/generic/libxvidcore.a,
make sure you compiled libxvidcore in ${with_xvid_tree}])
dnl     fi
dnl   else
dnl     CPPFLAGS="${CPPFLAGS_save} ${CPPFLAGS_xvid}"
dnl     LDFLAGS="${LDFLAGS_save} ${LDFLAGS_xvid}"
dnl     AC_CHECK_HEADERS(xvid.h, ,
dnl       [ AC_MSG_ERROR([Cannot find development headers for libxvidcore...]) ])
dnl     AC_CHECK_LIB(xvidcore, xvid_init, [
dnl       AX_ADD_PLUGINS([xvid])
dnl       AX_ADD_LDFLAGS([xvid],[-lxvidcore]) ],
dnl       [ AC_MSG_ERROR([Cannot find libxvidcore library...]) ])
dnl     LDFLAGS="${LDFLAGS_save}"
dnl     CPPFLAGS="${CPPFLAGS_save}"
dnl   fi
dnl fi
--------------------------------------------------------------------
we delete some dnl flags. 
then ./configure and make 
we only want to use codec xvid in vlc.
but the last error is mentioned in last mail.
how can we use the modules of xvid?
