Description:I cannot compile Asterisk, with SRTP.
I've build the libsrtp libraries with CentOS and pkgconfig standards, but Asterisk refuses to detect the libs.

Steps To Reproduce
On a CentOS minimal setup, install the libraries:
{noformat}
# rpm -ivh --nosignature http://rpm.axivo.com/redhat/axivo-release-6-1.noarch.rpm
# yum --enablerepo=axivo install libsrtp-devel
# find /usr/include -name srtp.h
/usr/include/srtp/srtp.h
/usr/include/openssl/srtp.h

$ cd SOURCES/asterisk-11.5.0
$ ./configure --host=x86_64-redhat-linux-gnu --build=x86_64-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --with-asound --with-bluetooth --with-cap --with-cpg --with-crypto --with-dahdi --with-gsm --with-iconv --with-iksemel --with-inotify --with-ldap --with-libcurl --with-libxml2 --with-ltdl --with-lua --with-mysqlclient --with-netsnmp --with-ogg --with-postgres --with-popt --with-pri --with-radius --with-spandsp --with-srtp --with-ss7 --with-speex --with-speexdsp --with-sqlite3 --with-ssl --with-tds --with-unixodbc --with-vorbis 'LDFLAGS=-lm -Wl,--as-needed -Wl,--strip-all'

Thanks for your comments. This does not appear to be a bug report and we are closing it. We appreciate the difficulties you are facing, but it would make more sense to raise your question in the support tracker, http://www.asterisk.org/support.

Hi Matt,

From my perspective I see it as a bug. The srtp package I use is identical to Fedora 19. If Asterisk is dependent on a specific srtp version, it should be mentioned... as current libsrtp is not detected by Asterisk. I am an experienced packager for Redhat as well Linux administrator, been doing this for last 10 years at work.

Regards,

Floren

I got it solved. The crucial option for srtp is --program-prefix:
{noformat}
export CFLAGS="%{optflags} -fPIC"
%configure --program-prefix=%{_prefix} --disable-static
{noformat}
You can get the precompiled libs for CentOS/Redhat 6 only at http://rpm.axivo.com.

Regards,

Floren
