LIBVERSION of libsmpp34
by Thorsten Alteholz 16 May '18

16 May '18

Hi, I stumbled upon LIBVERSION in src/Makefile.am of libsmpp34. Is there a reason why it changed from 0:1:0 to 1:0:0? At least the names of all exported symbols did not change!? Thorsten

OsmoHLR understanding/documentation/testing
by Mykola Shchetinin 16 May '18

16 May '18

Good day, ladies and gentlemen that's a great community you have. Mobile communications programming is a demanding field requiring best developers. I would be extremely grateful if you find time to answer a couple of my simple questions. I found myself reading the code of OsmoHLR project in order to understand how it works and how the GSUP protocol works (it seems that the only example of the GSUP-server is OsmoHLR). How do you understand the code when you need to modify it or accomplish other things that programmers usually do? It seems to not be documented much. Though I feel fluent in C, I find it hard to understand what is going on there. I've come up with an idea of running the OsmoHLR with a debugger. But in order to see what actually happens in the code when the location update is being performed (for example) I need to have the real phone and the real BTS, don't I? How do you check that the code is working as intended? Thank you very much! Kind regards, Mykola Shchetinin

I would expect your university has some BSC/network simulator or a core network+BSC to get those BTSs up and running? How were they used so far? If you have some kind of environment where the BTSs can be brought up, and you have some additional E1 interface cards so you can trace the interface between BSC and BTS, a significant step forward is made. However, if you don't have protocol-level documentation from Huawei or ZTE, and you cannot get any Abis protocol traces of BTS bring-up, it is almost impossible to get them ever supported from Osmocom, sorry. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

expected osmocom.org downtime on Sunday, 2018-05-13
by Harald Welte 14 May '18

14 May '18

Dear Osmocom community, this sunday (May 13), I'm planning to do some of the pending migration of osmocom.org services from our old server to a new machine. This will cause some downtime. Hopefully it will be minimal, but I'm sure there will be unexpected events that will mean some of the osmocom.org services will be unavailable at some point during Sunday. In terms of priorities, gerrit is high up on the list, so this will be my primary focus. If that goes well, redmine is the next on the list. In case you're interested in the gory details, https://osmocom.org/issues/3076 is the overview ticket. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmocom-bb installation problems
by Nikos Balkanas 12 May '18

12 May '18

Hi, I am new to this list. I use ubuntu 14.04.02. I am trying to configure/compile osmocom-bb. I have a few questions and problems: According to the src/README.building file, I should get the arm toolchain from gnuarm.com This should be updated, gnuarm.com doesn't have any downloads any more. Instead I installed gcc-arm-linux-gnueabi from ubuntu reps 1) normal gcc seems to support x-compiling for arm CPUs. Why not use that? 2) Your stock Makefile tests for CROSS_HOST against arm-elf-gcc. This should be updated to test also against arm-linux-gnueabi-gcc from gcc-arm-linux-gnueabi package 3) configure warnings: configure: WARNING: unrecognized options: --disable-tests, --disable-tests. Should be disabled if not supported any more checking for arm-linux-gnueabi-mt... no checking for mt... mt configure: WARNING: using cross tools not prefixed with host triplet Is this a problem? 4) configure asks for libosmovty. Despite listed, couldn't find it under osmocom libraries any more:( Where can i download it from? TIA, Nikos
