Fedora10下源码编译vlc-1.1.1 流程及注意事项（2）

（接上篇）

5：编译libavcodec.

下载，编译：http://www.ffmpeg.org/download.html

./configure --prifix=/root/soft/ffmpeg

make

编译过程极其漫长

完成之后输入make install即OK

作为一个过来者，我建议用下面这个命令编译：

./configure --prefix=/root/soft/ffmpeg --enable-swscale --enable-postproc --enable-gpl

否则，你将不得不执行步骤7和步骤8。 （这个操作特别有效，学习了）

6：继续编译，不用置疑，一定还是会提示libavcodec找不到，why？因为你放的目录程序找不到。这时候就要用到pkg-config了

export PKG_CONFIG_PATH="/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/root/soft/ffmpeg/lib/pkgconfig" 

(在Terminal输入上述代码，Enter，当然要注意你的安装位置是否跟上面相同)

export完成之后，我们可以测试一下：

[root@tsong vlc-1.0.6]# pkg-config --modversion libavcodec

52.20.1

如果可以打印出版本信息，那么OK，就可以继续编译了

7：继续编译。

编译命令还是

./configure --enable-run-as-root --prefix=/root/soft/vlc --with-mad=/root/soft/libmad/

继续提示缺少swscale：checking for SWSCALE... no

configure: error: Could not find libswscale. Use --disable-swscale to ignore this error. Proper software scaling and some video chroma conversion will be missing.

google了一下，发现swscale是ffmpeg到一个选项，默认在编译到时候没有启用。

[root@tsong ffmpeg-0.5.1]# ./configure --help|grep swscale

--enable-swscale enable GPLed software scaler support [no]

无奈，只好继续返回步骤5，用如下命令：

[root@tsong ffmpeg-0.5.1]# ./configure --prefix=/root/soft/ffmpeg --enable-swscale

然后再重复再编译安装ffmpeg

make

make install

8：完成步骤7中到swscale后，继续编译。

checking for ffmpeg/swscale.h... no

checking for POSTPROC... no

configure: error: Could not find libpostproc. Use --disable-postproc to ignore this error.

看报错在ffmpeg后面，该不会libpostproc也是ffmpeg到一个配置？

[root@tsong ffmpeg-0.5.1]# ./configure --help|grep postproc

--enable-postproc enable GPLed postprocessing support [no]

[root@tsong ffmpeg-0.5.1]# ./configure --prefix=/root/soft/ffmpeg --enable-swscale --enable-postproc

postproc is gpl and --enable-gpl is not specified.

If you think configure made a mistake, make sure you are using the latest

version from SVN. If the latest version fails, report the problem to the

[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.

Include the log file "config.err" produced by configure as this will help

solving the problem.

[root@tsong ffmpeg-0.5.1]# ./configure --prefix=/root/soft/ffmpeg --enable-swscale --enable-postproc --enable-gpl

无语，继续用./configure --prefix=/root/soft/ffmpeg --enable-swscale --enable-postproc --enable-gpl 命令编译ffmpeg

这可是第三次编译ffmpeg了！

9：继续编译：提示缺少a52

checking for a52dec/a52.h... no

configure: error: Could not find liba52 on your system: you may get it from http://liba52.sf.net/. Alternatively you can use --disable-a52 to disable the a52 plugin.

按照提示，从地址 http://liba52.sf.net下载，

./configure --prefix=/root/soft/a52dec

make

make install

10:编译好a52dec后，我们继续编译vlc

./configure --enable-run-as-root --prefix=/root/soft/vlc --with-mad=/root/soft/libmad/ --with-a52=/root/soft/a52dec/

11:

继续报错（这个本人之前乱搞的时候安装了）

checking for FRIBIDI... configure: error: Package requirements (fribidi) were not met:

No package 'fribidi' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.

Alternatively, you may set the environment variables FRIBIDI_CFLAGS

and FRIBIDI_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

从网址：http://fribidi.org/下载fribidi，然后编译安装。

[root@tsong fribidi-0.10.9]# ./configure --prefix=/root/soft/fribidi

make

make install

12：如步骤6，还是需要修改PKG_CONFIG_PATH，使之包含刚刚安装的fribidi

export PKG_CONFIG_PATH="/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/root/soft/ffmpeg/lib/pkgconfig:/root/soft/fribidi/lib/pkgconfig"

继续编译

13：继续报错（这个本人之前乱搞的时候安装了）

----------My god,我快失去耐心了。好在马上就结束了

checking for QT4... no

configure: WARNING: Qt 4 library not found

configure: error: The skins2 module depends on a the Qt4 development package. Without it you won't be able to open any dialog box from the interface, which makes the skins2 interface rather useless. Install the Qt4 development package or alternatively you can also configure with: --disable-qt4 --disable-skins2.

下载QT4，http://qt.nokia.com/downloads-cn 这又是一个大家伙，将近400MB呢，好在我之前已经下载编译好了，现在要做的就是指定pkg-config就可以了

14：还是让pkg-config可以找到qt4就可以了（/opt/qtsdk/qt/lib/pkgconfig）

export PKG_CONFIG_PATH="/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/root/soft/ffmpeg/lib/pkgconfig:/root/soft/fribidi/lib/pkgconfig:/opt/qtsdk/qt/lib/pkgconfig"

15：congratulations！

终于要成功了！

libvlc configuration

--------------------

version : 1.0.6

system : linux

architecture : i686 mmx sse sse2

build flavour : devel

vlc aliases : cvlc rvlc svlc qvlc

plugins/bindings :

You can tune the compiler flags in vlc-config.

To build vlc and its plugins, type `./compile' or `make'.

16：很遗憾，编译的时候再次出现错误提示：（这个小生没遇到，估计是因为以前把软件都乱装在了root）

ERROR : src/ft2_font.cpp:30: 29: fribidi/fribidi.h: No such file or directory

src/ft2_font.cpp: In member function 'virtual GenericBitmap* FT2Font::drawString(const UString&, uint32_t, int) const':

ERROR : src/ft2_font.cpp: 157: 'FriBidiCharType' was not declared in this scope

google：http://svn.tribler.org/vlc/trunk/modules/gui/skins2/src/ft2_font.cpp

查找代码ft2_font.cpp,在目录/root/download/vlc-1.0.6/modules/gui/skins2/src 下，看到了

#include <fribidi/fribidi.h>

因为我们的fribidi是安装在/root/soft/fribidi目录，不是默认安装在/usr/include目录，那么建立符号链接！

[root@tsong include]# ln -s /root/soft/fribidi/include/fribidi/ fribidi

[root@tsong include]# pwd

/usr/include

17：继续

make         （漫长等待）

make install（漫长等待）

18：done   （这个时候你可以去查看VLC是否乖乖地躺在Applications--Sound&Video的选项里了）

19：编辑文件/usr/share/applications /vlc.desktop
