没有用于在 Ubuntu 上构建 freeswitch 的 speex 包

Question

我正在尝试freeswitch在 Ubuntu上构建并且缺少许多库。其中之一是speex。configure说它不存在，而dpkg说它在这里：

checking for speex >= 1.2rc1 speexdsp >= 1.2rc1... Package speex was not found in the pkg-config search path. Perhaps you should add the directory containing `speex.pc' to the PKG_CONFIG_PATH environment variable No package 'speex' found Package speexdsp was not found in the pkg-config search path. Perhaps you should add the directory containing `speexdsp.pc' to the PKG_CONFIG_PATH environment variable No package 'speexdsp' found
configure: error: Library requirements (speex >= 1.2rc1 speexdsp >= 1.2rc1) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.

为什么？以及如何解决？

Answer 1

你需要安装 libspeex-dev

sudo apt-get install libspeex-dev

所以，你会得到以下结果：

saman@jack:~$ dpkg -l *speex*

Answer 2

您可能还需要安装libspeexdsp-dev软件包（取决于libspeex-dev）：

sudo apt-get install libspeexdsp-dev
