在linux(ubuntu)下编译VLC中出现的问题

首先安装依赖库：

apt-get install -ylibdbus-1-dev lua5.1 liblua5.1-dev libmad0-dev libavcodec-dev libavformat-devlibswscale-dev libpostproc-dev liba52-dev libxcb1-dev libxcb-shm0-devlibxcb-xv0-dev libx11-xcb-dev libgl1-mesa-dev libqt4-dev libgcrypt11-dev

下载vlc，ftp://ftp.videolan.org/pub/videolan/vlc/



然后用最新的VLC-2.2.1编译，出现如下错误：

__builtin_unreachable，编译时出现这个错误！

在<vlc_common.h>中定义：

#ifdef __GNUC__ //gcc编译器定义的一个宏

# definelikely(p) __builtin_expect(!!(p), 1)

# defineunlikely(p) __builtin_expect(!!(p), 0)

# defineunreachable() __builtin_unreachable()

#else

# definelikely(p) (!!(p))

# defineunlikely(p) (!!(p))

# defineunreachable() ((void)0)

#endif

GCC编译

typedef structfilter_owner_t

{

void *sys;



union

{

struct

{

picture_t * (*buffer_new)( filter_t* );

} video;

struct

{

subpicture_t * (*buffer_new)(filter_t * );

} sub;

};

} filter_owner_t;

认为定义有问题，如果修改的话，涉及的地方又比较多，实在难以处理。

而且，类似这样的定义很多，无法处理。



但编译vlc-1.1.7是通过的。

接着下载vlc-2.2.1编译就出现如下错误 ：

CC video_chroma/libi420_rgb_mmx_plugin_la-i420_rgb16_x86.lo

V2.1.5也不行：

CC libdeinterlace_plugin_la-algo_x.lo

deinterlace/algo_x.c:503:internal compiler error: in memory_address, at explow.c:493

Please submit afull bug report,

with preprocessedsource if appropriate.

V2.1.2还是不行：

CC libdeinterlace_plugin_la-algo_x.lo

deinterlace/algo_x.c:In function ‘XDeintBand8x8MMXEXT’:

See<file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions.

V2.0.1编译正常：

编译选项：

./configure--disable-lua --disable-mad --disable-avcodec --disable-avformat--disable-swscale --disable-postproc --disable-a52 --disable-mkv

实际上，就不要ffmpeg。如果包括进来的话，configure会出错：

checking for***CODEC... yes

configure: error:libavcodec versions 55 and later are not supported yet.

配套的ffmpeg要退回到ffmpeg1.2.12。
