毕业设计辛酸路—在ubuntu下安装mplayer以及遇到的问题

今天尝试在ubuntu下安装mplayer，发现了很多以前没有遇到过的问题，记录下来，以便以后参考！
当./configure的时候，遇到以下错误：
1.Error: The GUI requires libavcodec with PNG support (needs zlib).
Check "configure.log" if you do not understand why it failed.
解决方法：
$wget http://www.zlib.net/zlib-1.2.3.tar.gz
$tar -xvzf zlib-1.2.3.tar.gz
$cd zlib-1.2.3.tar.gz
$./configure
$make $sudo make install
或者：最简单的方法
sudo apt-get install libpng12-dev
2.Error: X11 support required for GUI compilation.
Check "configure.log" if you do not understand why it failed.
解决方法：
sudo apt-get install libgtk1.2-dev
这会安装了15个包：

　　libglib1.2 libglib1.2-dev libgtk1.2 libgtk1.2-common libgtk1.2-dev libx11-dev libxau-dev libxdmcp-dev libxext-dev libxi-dev pkg-config x11proto-core-dev x11proto-input-dev x11proto-kb-dev x11proto-xext-dev
终于./configure 过了！！
3.make 后，又出现错误了：
In file included from mplayer.c:59:

libvo/font_load.h:5:22: error: ft2build.h: No such file or directory

libvo/font_load.h:6:10: error: #include expects "FILENAME" or

In file included from mplayer.c:59:

libvo/font_load.h:40: error: expected specifier-qualifier-list before 'FT_Face'

make: *** [mplayer.o] 错误 1

　 其实在编译时加入--enable-freetype参数是为了解决字幕乱码的问题，但是加了之后make时出错.不加--enable- freetype是可以正常编译，不过GUI和字幕均为乱码.请教了N个人,最后得知,问题是因为当初安装编译环境的时候选择的是GTK1.2，更新为 2.0既可顺利编译:

sudo apt-get install libgtk2.0-dev

　　make一下,各种warning,看得我都眼花,还好最后通过了,最后

sudo make install

4.但我编译的时候，又出现错误了：

vo_ivtv.c: In function 'ivtv_reset':
vo_ivtv.c:79: error: storage size of 'sd' isn't known
vo_ivtv.c:80: error: storage size of 'sd1' isn't known
vo_ivtv.c:84: error: 'IVTV_STOP_FL_HIDE_FRAME' undeclared (first use in this function)
vo_ivtv.c:84: error: (Each undeclared identifier is reported only once
vo_ivtv.c:84: error: for each function it appears in.)
vo_ivtv.c:87: error: 'IVTV_IOC_STOP_DECODE' undeclared (first use in this function)
vo_ivtv.c:97: error: 'IVTV_IOC_START_DECODE' undeclared (first use in this function)
vo_ivtv.c:80: warning: unused variable 'sd1'
vo_ivtv.c:79: warning: unused variable 'sd'
make[1]: *** [vo_ivtv.o] Error 1
make[1]: Leaving directory `/home/soul/software/mplayer/MPlayer-1.0rc2/libvo'
make: *** [libvo/libvo.a] 错误 2

　　出现上面的错误后，首先运行make distclean 清除一下。

　　在./configure ...... 那一些参数后在加 一个 --disable-ivtv 。

在make，经过N久，终于成功了！
然后make install
