從官網下載了最新的opus 1.3的代碼，然后按照readme說明進行編譯。

配置的時候出現(xiàn)如下錯誤：

$ ./autogen.sh

Updating build configuration files, please wait....

configure.ac:38: warning: macro 'AM_PROG_LIBTOOL' not found in library

configure.ac:38: error: possibly undefined macro: AM_PROG_LIBTOOL

? ? ? If this token and others are legitimate, please use m4_pattern_allow.

? ? ? See the Autoconf documentation.

autoreconf: /usr/bin/autoconf failed with exit status: 1

搜索了一下，缺少libtool，安裝解決

$ sudo apt-get install libtool

接著來了第二個錯誤：

$ ./autogen.sh

Updating build configuration files, please wait....

libtoolize: putting auxiliary files in '.'.

libtoolize:? error: linking '/usr/share/libtool/build-aux/ltmain.sh' to './' failed

libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'm4'.

libtoolize:? error: linking '/usr/share/aclocal/libtool.m4' to 'm4/' failed

libtoolize:? error: linking '/usr/share/aclocal/ltoptions.m4' to 'm4/' failed

libtoolize:? error: linking '/usr/share/aclocal/ltsugar.m4' to 'm4/' failed

libtoolize:? error: linking '/usr/share/aclocal/ltversion.m4' to 'm4/' failed

libtoolize:? error: linking '/usr/share/aclocal/lt~obsolete.m4' to 'm4/' failed

autoreconf: libtoolize failed with exit status: 1

原因是opus編譯代碼在我的共享文件夾下面，造成了權限問題。對我用的虛擬機VBox。

重新克隆一份opus代碼到/usr/home下，再次執(zhí)行autogen.sh，成功。

there's actually another situation that can cause the libtoolize that was not really addressed here. Permission and access issues. Consider the following situation: you're in virtualbox and trying to run libtoolize out of a VBox Shared folder, you will get this error. Move the project within the machine, error is gone.
