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：

    # automake-1.10 (recommended) is not available on Fedora 8

    AUTOMAKE=automake-${AM_VERSION}
