    [ https://issues.asterisk.org/jira/browse/ASTERISK-23424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=216175#comment-216175 ] 

Matt Jordan commented on ASTERISK-23424:
----------------------------------------

That can't always be done.

There is not always a {{libsrtp}} for all systems Asterisk builds on.

The correct solution here is to pass {{--with-external-srtp}} to pjproject when it is built, such that it does not provide the SRTP library itself. This is documented on the [wiki page|https://wiki.asterisk.org/wiki/display/AST/Installing+pjproject#Installingpjproject-BuildingandInstallingpjproject] for building/installing pjproject.

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Core/BuildSystem, Resources/res_srtp
>    Affects Versions: 12.0.0
>         Environment: Arch Linux 2013.05 x32 3.8.4-1-ARCH (tobias at testing) (gcc version 4.7.2 (GCC) ) #1 SMP PREEMPT
>            Reporter: capouch
>            Severity: Minor

> Arch Linux ships w/o built-in srtp library.  This is detected by the pjproject build system, which as a result builds and installs the included (~third-party/srtp) library.  The resulting .so file has a dependency on libpj.so.
> This dependency breaks the configure script in two places where the undefined reference to pj_log in libsrtp.so bombs the script, with the result that the Asterisk build system mistakenly thinks there is no srtp library on the machine.
> The fix is in this case trivial; add -lsrtp to the set of build libraries specified for the errant tests.  Issue is present in both 12.0.0 and 12.1.0.
