StriShaken module compilation - sr-users

29 May 2024

Hello all!

I am struggling on compiling StriShaken module on RHEL 9.2.
So far, the module was compiled as well as libstirshaken.
Below are the steps used to compile (as sudo) both library and module (I
hope this may help someone) and, of course, correct me if I am wrong in any
step or if there is a better way.
Also, note that the RHEL 9,2 is in a VM environment without access to the
WWW, instead it uses Red Hat Satellite to download packages (via Yum or
DNF), if available.

Lib LibKS

download libks from https://github.com/signalwire/libks
unzip
move to dir created by Unzip
run
yum groupinstall "Development Tools"
dnf install libuuid-devel libatomic openssl-devel
cmake .
make
make install
cp /usr/lib/pkgconfig/libks2.pc /usr/lib64/pkgconfig/.

For module LibStirShaken:

download https://github.com/signalwire/libstirshaken
unzip
move to dir
if using OpenSSL3.0 or + edit file configure.ac and add after line 28:
if test x$HAVE_OPENSSL = x1; then
openssl_CFLAGS="$openssl_CFLAGS -DHAVE_OPENSSL";
/* PATCH FOR OPENSSL3 */
AC_MSG_CHECKING([for OpenSSL >= 3.0.0])
AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[
#include <openssl/opensslv.h>
#if OPENSSL_VERSION_PREREQ(3,0)
#error "you_have_version_3"
#endif
]], [[]])],
[ AC_MSG_RESULT([no]) ],
[ AC_MSG_RESULT([yes]);
AC_DEFINE(OPENSSL_SUPPRESS_DEPRECATED, 1, [disable openssl
deprecated-function warnings]) ])
/* END OF PATCH */
else
AC_MSG_ERROR([OpenSSL >= 1.0.1e and associated developement headers
required])
fi
run
     configure
     make
    sudo make install

next, move to dir /root/kamailio/kamailio-5.7.4/src/modules/stirshaken
cd /root/kamailio/kamailio-5.7.4/src/modules/stirshaken
ln -s /root/stirshakenlib/libks-master/src/include/libks libks
make
make install

All seem to compile OK , *but* when starting Kamailio I get the following
errors:

May 29 17:42:02 kamailio1 kamailio[248991]: ERROR: <core>
[core/sr_module.c:599]: ksr_load_module(): could not open module

/usr/local/etc/kamailio/kamailio_stir_shaken_mod.cfg, line 106, column

I haven't found a solution for this.
Can anyone help?

Thanks in advance!
