In 《Linux-based open-source VOIP system LinPhone [4]This section briefly introduces the compilation of readline, osip, eXosip, and ncurses libraries. If you need to compile linphone, you may need a third-party library libogg when compiling speex, but you don't need it, so how can you do it? I can open the source code and modify it. As shown in:

To disable libogg compilation for speex, You need to modify several files and use automake to generate them again.ConfigureFile, the steps are as follows:

1): Modify the configure. ac File

Open the configure. ac file, find the configuration options with the ogg character, and delete all the items. The items to be modified are as follows (the items selected in yellow ):

One of the areas to be modified:Delete all the following statements

Second place to be modified:Delete all the following statements

The third place to be modified:Delete src/Makfile

Where to modify:Delete all the following statements

Save and modify the Makefile. am file. The configure. ac file after modification is as follows:

2): Modify the Makefile. am File

Open the Makefile. am file, find the configuration options with the src character, and delete all the items. The items to be modified are as follows (the items selected in yellow ):

Delete all codes with the src character, as shown below:

The modified Makefile. am file is as follows:

3): Create an autogen. sh file.

The purpose of creating this file is to automatically execute automake, autoconf, and aclocal. As follows:

#!/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

After creating the autogen. sh file, you can run it. As follows:

At the same time, create a build. sh file under the speex1.2 directory, as shown below:

After the./build. sh file is executed, as long as no error occurs, the so dynamic library is generated in the _ install Folder, as shown below:
