在《 基于Linux开源VOIP系统LinPhone[四] 》中，简单的介绍了readline、osip、eXosip以及ncurses库的编译，如果需要编译linphone的话，当然在编译speex的时候，可能还需要一个第三方库libogg，不过也可以不用它，那么怎么做呢，我可以打开源码，来修改一下。如下图所示：
如果想要speex不编译libogg的话，需要修改几个文件，同时还需要用automake重新生成configure文件，其步骤如下：
一）：修改configure.ac文件
打开configure.ac文件之后，查找带有ogg字样的配置选项，全部删除，需要修改的地方如下所示（黄色选中的地方）：
需要修改的地方之一：下面的语句全部删除
需要修改的地方之二：下面的语句全部删除
需要修改的地方之三：删除src/Makfile
需要修改的地方之四：下面的语句全部删除
最后保存，同时需要修改Makefile.am这个文件。修改之后的configure.ac文件如下：

二）：修改Makefile.am文件
打开Makefile.am文件之后，查找带有src字样的配置选项，全部删除，需要修改的地方如下所示（黄色选中的地方）：
将带有src字样的代码全部删除，如下所示：
整个修改之后的Makefile.am文件如下：
三）：建立一个autogen.sh文件
建立这个文件的目的：自动取执行automake、autoconf、aclocal等。如下所示：
#!/bin/sh#AM_VERSION="1.10"if ! type aclocal-$AM_VERSION 1>/dev/null 2>&1; then# automake-1.10 (recommended) is not available on Fedora 8AUTOMAKE=automakeACLOCAL=aclocalelseACLOCAL=aclocal-${AM_VERSION}AUTOMAKE=automake-${AM_VERSION}fiINTLTOOLIZE=/usr/bin/intltoolizeif test -f /opt/local/bin/intltoolize ; thenINTLTOOLIZE=/opt/local/bin/intltoolizeelseINTLTOOLIZE=/usr/bin/intltoolizefilibtoolize="libtoolize"for lt in glibtoolize libtoolize15 libtoolize14 libtoolize13 ; do if test -x /usr/bin/$lt ; then libtoolize=$lt ; break fi if test -x /usr/local/bin/$lt ; then libtoolize=$lt ; break fi if test -x /opt/local/bin/$lt ; then libtoolize=$lt ; break fidoneif test -d /usr/local/share/aclocal ; thenACLOCAL_ARGS="$ACLOCAL_ARGS -I /usr/local/share/aclocal"fiif test -d /share/aclocal ; then ACLOCAL_ARGS="$ACLOCAL_ARGS -I /share/aclocal"fiecho "Generating build scripts in mediastreamer..."set -x$libtoolize --copy --force$INTLTOOLIZE --copy --force --automake$ACLOCAL $ACLOCAL_ARGSautoheader$AUTOMAKE --force-missing --add-missing --copyautoconf
建立好autogen.sh文件之后，就可以运行它了。如下所示：
同时在speex1.2目录下建立一个build.sh文件，如下所示：
最后执行./build.sh文件之后，只要没有出现错误，会在_install文件夹中生成so动态库，如下所示：
不是每一次努力都有收获，但是，每一次收获都必须经过努力。
