在《 基於Linux開源VOIP系統LinPhone[四] 》中，簡單的介紹了readline、osip、eXosip以及ncurses庫的編譯，如果需要編譯linphone的話，當然在編譯speex的時候，可能還需要一個第三方庫libogg，不過也可以不用它，那麼怎麼做呢，我可以開啟源碼，來修改一下。如所示：

如果想要speex不編譯libogg的話，需要修改幾個檔案，同時還需要用automake重建configure檔案，其步驟如下：

一）：修改configure.ac檔案

開啟configure.ac檔案之後，尋找帶有ogg字樣的配置選項，全部刪除，需要修改的地方如下所示（黃色選中的地方）：

需要修改的地方之一：下面的語句全部刪除

需要修改的地方之二：下面的語句全部刪除

需要修改的地方之三：刪除src/Makfile

需要修改的地方之四：下面的語句全部刪除

最後儲存，同時需要修改Makefile.am這個檔案。修改之後的configure.ac檔案如下：

二）：修改Makefile.am檔案

開啟Makefile.am檔案之後，尋找帶有src字樣的配置選項，全部刪除，需要修改的地方如下所示（黃色選中的地方）：

將帶有src字樣的代碼全部刪除，如下所示：

整個修改之後的Makefile.am檔案如下：

三）：建立一個autogen.sh檔案

建立這個檔案的目的：自動取執行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檔案之後，就可以運行它了。如下所示：

同時在speex1.2目錄下建立一個build.sh檔案，如下所示：

最後執行./build.sh檔案之後，只要沒有出現錯誤，會在_install檔案夾中產生so動態庫，如下所示：
