交叉编译用于ARM的Sphinxbase和Pocketsphinx

我正在尝试使Pocketsphinx在基于ARM的处理器上工作，用于热词检测。因此，我正在Ubuntu PC上交叉编译Sphinxbase和Pocketsphinx for ARM。我能够在64位Ubuntu PC上安装Sphinxbase和Pocketsphinx，并使用以下命令使热词检测正常工作：

$/pocketsphinx\u连续-输入是-关键词“天”-kws\u阈值20

但我在交叉编译Sphinxbase时收到错误日志。我首先使用以下命令交叉编译Sphinxbase

$/autogen.sh

$/configure--host=arm-linux-gnueabihf--build=x86_64-linux-gnu--prefix=/home/rakesh/sphinx–不带python

上述命令的部分日志如下所示：

checking for pthread_create in -lpthread... yes
checking pulse/pulseaudio.h usability... no
checking pulse/pulseaudio.h presence... no
checking for pulse/pulseaudio.h... no
checking alsa/asoundlib.h usability... yes
checking alsa/asoundlib.h presence... yes
checking for alsa/asoundlib.h... yes
checking for snd_pcm_open in -lasound... no
checking for doxygen... no

当我发出make命令时，我得到以下错误日志：

有人能提出解决错误的方案吗。

根据他们在的示例Android项目，他们为Android预先构建的pocketsphinx库（即ARM）与sphinxbase链接在一起，但不包括与访问音频设备相关的方法，即

ad\u open

，

ad\u start\u rec

，

ad\u read

。换句话说，他们的预构建库需要在您选择的音频库的帮助下手动向pocketsphinx提供音频样本。 查看用于创建此“组合”版本库的源文件，网址为：

在构建sphinxbase时，脚本试图检测可用的音频库：您应该尝试强制它为“无”，希望它仍能编译
