ubuntu18.04安裝openSMILE教程以及出錯解決辦法

首先安裝依賴：

$sudo apt-get install automake

$sudo apt-get install autoconf

$sudo apt-get install libtool

$sudo apt-get install m4

$sudo apt-get install gcc

從官網下載安裝包：https://www.audeering.com/opensmile/

執行以下命令：

tar -zxvf opensmile-2.3.0.tar.gz

cd opensmile-2.3.0

bash autogen.sh

bash autogen.sh

./configure

make -j4 ; make

make install

注意：你必須執行兩遍bash autogen.sh 這一步，因爲如果只裝一遍的話，必要的文件很可能不會裝全。

安裝成功：

$ ./SMILExtract -h

我遇到的出錯的原因：

Makefile:1457: recipe for target 'src/core/libopensmile_la-componentManager.lo' failed
make: *** [src/core/libopensmile_la-componentManager.lo] Error 1
failed to build or install openSMILE to '/opensmile/opensmile-2.3.0/inst'!
buildStandalone.sh: 64: exit: Illegal number: -1

查找錯誤信息：

src/include/core/vectorTransform.hpp:117:83: error: narrowing conversion of ‘'\37777777756'’ from ‘char’ to ‘unsigned char’ inside { } [-Wnarrowing]
 const unsigned char smileMagic[] = {(char)0xEE, (char)0x11, (char)0x11, (char)0x00};
                                                                                   ^
In file included from src/core/vectorTransform.cpp:112:0:

修改方案：

找到相應目錄，然後打開vectorTransform.hpp文件

將第117行代碼改爲

 const char smileMagic[] = {(char)0xEE, (char)0x11, (char)0x11, (char)0x00};

保存後，再編譯，安裝即可。
