Question

我正在尝试使Pocketsphinx在基于ARM的处理器上工作以进行热字检测。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字检测正常工作：

$ ./ pocketsphinx_continuous -inmic yes-关键字“ day” -kws_threshold 20

但是在交叉编译Sphinxbase时出现错误日志。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 –without-python

上面命令的日志的某些部分如下：

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

发出 make 命令时，我收到以下错误日志：

有人可以建议解决错误的方法吗？

根据他们位于https://github.com/cmusphinx/pocketsphinx-android-demo的示例Android项目，他们针对Android（例如ARM）的预建Pocketsphinx库与sphinxbase链接在一起，但不包括与访问音频设备有关的方法，例如ad_open，{{1 }}，ad_start_rec。换句话说，他们的预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。在以下位置查看使用哪些源文件来创建此“组合”版本的库： https://github.com/cmusphinx/pocketsphinx-android/blob/master/CMakeLists.txt

在构建sphinxbase时，脚本尝试检测可用的音频库：https://github.com/cmusphinx/sphinxbase/blob/master/configure.ac#L118您应该尝试将其强制为“ none”，并希望它仍然可以编译。

为ARM交叉编译Sphinxbase和Pocketsphinx
