No speex packages for freeswitch building on Ubuntu

Question

I am trying to build freeswitch on Ubuntu and getting numerous libraries absent. One of them is speex. configure says it is absent while dpkg says it is here:

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.

why? and how to fix?

Solution 1

You need to install libspeex-dev

sudo apt-get install libspeex-dev

So, you will have below result :

saman@jack:~$ dpkg -l *speex*
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-=================================
ii  libspeex-dev:a 1.2~rc1.1-1u amd64        The Speex codec library developme
ii  libspeex1:amd6 1.2~rc1.1-1u amd64        The Speex codec runtime library
ii  libspeexdsp1:a 1.2~rc1.1-1u amd64        The Speex extended runtime librar
un  speex          <none>       <none>       (no description available)

Solution 2

You may also need to install the libspeexdsp-dev package (which depends on libspeex-dev):

sudo apt-get install libspeexdsp-dev

How would I know that?

[sparkmood]

Did you try that?

Yes, but in general, how would I know library names if they different?
