Alexander Traud commented on ASTERISK-27475:
--------------------------------------------

[~samfun], good catch! When one goes for {{ldd /usr/lib/asterisk/modules/codec_opus.so}}, you see the dependencies. This issue got missed because {{libcurl}} is installed as default on many Linux distributions, even on your Ubuntu 16.04 LTS for Desktops.

Currently, the fix was to add ‘curl’ as dependency in {{make menuselect}}. However in the {{./configure}} script of Asterisk, that ‘curl’ is not just the shared library (.so) but also the header files and a tool called {{curl-config}}. Furthermore, {{libcurl-dev}} is a virtual package in Debian/Ubuntu. Consequently to get transcoding for the Opus Codec, one to go for

{{sudo apt install libcurl4-openssl-dev}}

with the upcoming Asterisk 13.19 and Asterisk 15.2. Moreover in Ubuntu 14.04 LTS, that packages requires/installs several other packages, enabling many features in Asterisk as side effect (like SIP-over-TLS, LDAP, …).

Therefore: Could the Digium team double-check whether {{curl}} is really required? Alternatively, the build system should be enhanced to look not for the headers but just for the shared library of curl. I do not have the resources to do that change right now, especially because I do not use the Opus Codec module of Digium personally. Just a suggestion, because this change here is going to create unforeseen support requests.

> If libcurl is not present on the platform when building Asterisk everything will still build and codec_opus will be downloaded however there will be not translation path available for Opus.
> Reason is that Opus requires libcurl. Once libcurl is installed then Opus will show up in the translation path.
> Probably should be documented or stated as a requirement next to xmlstarlet in the menuselect options.
