Introduction
One day I’ve invented that it would be nice to play with real SS7 stack. The only available I’ve found is OpenSS7
Day 1 – 30/04/2009
Compiling from source files – failed. Somehow it breaks on my Fedora Core 10:
In file included from ../../openss7-0.9.2.G/streams/src/kernel/specfs.c:124: ../../openss7-0.9.2.G/streams/src/kernel/strspecfs.c: In function ‘specfs_init_cache’: ../../openss7-0.9.2.G/streams/src/kernel/strspecfs.c:1406: warning: passing argument 5 of ‘kmem_cache_create’ from incompatible pointer type ../../openss7-0.9.2.G/streams/src/kernel/strspecfs.c:1406: error: too many arguments to function ‘kmem_cache_create’
Google research didn’t help…
Next try with precompiled packages: i’ve installed proper repo for yum:
[jhartman@jhartman yum.repos.d]$ pwd /etc/yum.repos.d [jhartman@jhartman yum.repos.d]$ cat openss7.repo [openss7] enabled = 1 name = OpenSS7 Repository baseurl = http://www.openss7.org/repos/rpms/fedora/9/i686 gpgcheck = 1 gpgkey = http://www.openss7.org/pubkey.asc
Shiii…. – again failure:

The problem seems to be rpm package installed on Fedora Core 10 in version 4.6 (notice that OpenSS7 binaries are targeting FC9)…
Next idea – compile rpm 4.4 from the source and put missing libraries into /usr/lib manually….
Nop…. bad idea. Small hint – do not try to force downgrade rpm! I spent 2 hours trying install rpm without rpm (and of course – without yum).
Finally – I gave up. Installed Fedora Core 9 on my VMWare and… still problems:

That’s all for today 🙁
To be continued…. I hope
My fight with OpenSS7
Hey, Jarek.
Thanks for your blog insights. They’re all very interesting.
Did you have any more luck getting OpenSS7 going since your initial attempt? I am about to embark on a project that will make heavy use of it and I wondered if you had any more insights.
One thing that would be useful to know from you is whether OpenSS7 implements its own internal ASN.1 encoder/decoder successfully or whether an external one is required.
