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-$AM_VERSION 1>/dev/null 2>&1; then # automake-1.10 (recommended) is not available on Fedora 8 AUTOMAKE=automake ACLOCAL=aclocal else ACLOCAL=aclocal-${AM_VERSION} AUTOMAKE=automake-${AM_VERSION} fi INTLTOOLIZE=/usr/bin/intltoolize if test -f /opt/local/bin/intltoolize ; then INTLTOOLIZE=/opt/local/bin/intltoolize else INTLTOOLIZE=/usr/bin/intltoolize fi libtoolize="libtoolize" for lt in glibtoolize libtoolize15 libtoolize14 libtoolize13 ; do if test -x /usr/bin/$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=$lt ; break fi done if test -d /usr/local/share/aclocal ; then ACLOCAL_ARGS="$ACLOCAL_ARGS -I /usr/local/share/aclocal" fi if test -d /share/aclocal ; then ACLOCAL_ARGS="$ACLOCAL_ARGS -I /share/aclocal" fi echo "Generating build scripts in mediastreamer..." set -x $libtoolize --copy --force $INTLTOOLIZE --copy --force --automake $ACLOCAL $ACLOCAL_ARGS autoheader $AUTOMAKE --force-missing --add-missing --copy autoconf
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:
